<p>
The bitstream format is an abstract encoding of structured data, very
similar to XML in some ways. Like XML, bitstream files contain tags, and nested
structures, and you can parse the file without having to understand the tags.
Unlike XML, the bitstream format is a binary encoding, and unlike XML it
provides a mechanism for the file to self-describe "abbreviations", which are
effectively size optimizations for the content.</p>

<li>A "<a href="#magic">magic number</a>" that identifies the contents of
the stream.</li>
<li>Encoding <a href="#primitives">primitives</a> like variable bit-rate

A bitstream literally consists of a stream of bits. This stream is made up of a
number of primitive values that encode a stream of unsigned integer values.
These
integers are are encoded in two ways: either as <a href="#fixedwidth">Fixed
Width Integers</a> or as <a href="#variablewidth">Variable Width
Integers</a>.

<p>Fixed-width integer values have their low bits emitted directly to the file.
For example, a 3-bit integer value encodes 1 as 001. Fixed width integers
are used when there are a well-known number of options for a field. For
example, boolean values are usually encoded with a 1-bit wide integer.

<p>Variable-width integer (VBR) values encode values of arbitrary size,
optimizing for the case where the values are small. Given a 4-bit VBR field,
any 3-bit value (0 through 7) is encoded directly, with the high bit set to
zero. Values larger than N-1 bits emit their bits in a series of N-1 bit
chunks, where all but the last set the high bit.</p>
<p>For example, the value 27 (0x1B) is encoded as 1011 0011 when emitted as a
vbr4 value. The first set of four bits indicates the value 3 (011) with a
continuation piece (indicated by a high bit of 1). The next word indicates a
value of 24 (011 << 3) with no continuation. The sum (3+24) yields the value
27.

<p>
A bitstream is a sequential series of <a href="#blocks">Blocks</a> and
<a href="#datarecord">Data Records</a>. Both of these start with an
abbreviation ID encoded as a fixed-bitwidth field. The width is specified by
the current block, as described below. The value of the abbreviation ID
specifies either a builtin ID (which have special meanings, defined below) or
one of the abbreviation IDs defined by the stream itself.
</p>
<p>
The set of builtin abbrev IDs is:
</p>
<ul>
<li>0 - <a href="#END_BLOCK">END_BLOCK</a> - This abbrev ID marks the end of the
current block.</li>
<li>1 - <a href="#ENTER_SUBBLOCK">ENTER_SUBBLOCK</a> - This abbrev ID marks the
beginning of a new block.</li>
<li>2 - <a href="#DEFINE_ABBREV">DEFINE_ABBREV</a> - This defines a new
abbreviation.</li>
<li>3 - <a href="#UNABBREV_RECORD">UNABBREV_RECORD</a> - This ID specifies the
definition of an unabbreviated record.</li>
</ul>
<p>Abbreviation IDs 4 and above are defined by the stream itself, and specify
an <a href="#abbrev_records">abbreviated record encoding</a>.</p>
</div>
<!-- ======================================================================= -->
<div class="doc_subsection"><a name="blocks">Blocks</a>
</div>
<div class="doc_text">
<p>
Blocks in a bitstream denote nested regions of the stream, and are identified by
a content-specific id number (for example, LLVM IR uses an ID of 12 to represent
function bodies). Nested blocks capture the hierachical structure of the data
encoded in it, and various properties are associated with blocks as the file is
parsed. Block definitions allow the reader to efficiently skip blocks
in constant time if the reader wants a summary of blocks, or if it wants to
efficiently skip data they do not understand. The LLVM IR reader uses this
mechanism to skip function bodies, lazily reading them on demand.
</p>
<p>
When reading and encoding the stream, several properties are maintained for the
block. In particular, each block maintains:
</p>
<ol>
<li>A current abbrev id width. This value starts at 2, and is set every time a
block record is entered. The block entry specifies the abbrev id width for
the body of the block.</li>
<li>A set of abbreviations. Abbreviations may be defined within a block, or
they may be associated with all blocks of a particular ID.
</li>
</ol>
<p>As sub blocks are entered, these properties are saved and the new sub-block
has its own set of abbreviations, and its own abbrev id width. When a sub-block
is popped, the saved values are restored.</p>

<p>
The ENTER_SUBBLOCK abbreviation ID specifies the start of a new block record.
The <tt>blockid</tt> value is encoded as a 8-bit VBR identifier, and indicates
the type of block being entered (which is application specific). The
<tt>newabbrevlen</tt> value is a 4-bit VBR which specifies the
abbrev id width for the sub-block. The <tt>blocklen</tt> is a 32-bit aligned
value that specifies the size of the subblock, in 32-bit words. This value

</div>
<div class="doc_text">
<p>
Data records consist of a record code and a number of (up to) 64-bit integer
values. The interpretation of the code and values is application specific and
there are multiple different ways to encode a record (with an unabbrev record
or with an abbreviation). In the LLVM IR format, for example, there is a record
which encodes the target triple of a module. The code is MODULE_CODE_TRIPLE,
and the values of the record are the ascii codes for the characters in the
string.</p>

<p>An UNABBREV_RECORD provides a default fallback encoding, which is both
completely general and also extremely inefficient. It can describe an arbitrary
record, by emitting the code and operands as vbrs.</p>
<p>For example, emitting an LLVM IR target triple as an unabbreviated record
requires emitting the UNABBREV_RECORD abbrevid, a vbr6 for the
MODULE_CODE_TRIPLE code, a vbr6 for the length of the string (which is equal to
the number of operands), and a vbr6 for each character. Since there are no
letters with value less than 32, each letter would need to be emitted as at
least a two-part VBR, which means that each letter would require at least 12
bits. This is not an efficient encoding, but it is fully general.</p>

<div class="doc_text">
<p><tt>[&lt;abbrevid&gt;, fields...]</tt></p>
<p>An abbreviated record is a abbreviation id followed by a set of fields that
are encoded according to the <a href="#abbreviations">abbreviation
definition</a>. This allows records to be encoded significantly more densely
than records encoded with the <a href="#UNABBREV_RECORD">UNABBREV_RECORD</a>
type, and allows the abbreviation types to be specified in the stream itself,
which allows the files to be completely self describing. The actual encoding
of abbreviations is defined below.
</p>
</div>
<!-- ======================================================================= -->
<div class="doc_subsection"><a name="abbreviations">Abbreviations</a>
</div>
<div class="doc_text">
<p>
Abbreviations are an important form of compression for bitstreams. The idea is
to specify a dense encoding for a class of records once, then use that encoding
to emit many records. It takes space to emit the encoding into the file, but
the space is recouped (hopefully plus some) when the records that use it are
emitted.
</p>
<p>
Abbreviations can be determined dynamically per client, per file. Since the
abbreviations are stored in the bitstream itself, different streams of the same
format can contain different sets of abbreviations if the specific stream does
not need it. As a concrete example, LLVM IR files usually emit an abbreviation
for binary operators. If a specific LLVM module contained no or few binary
operators, the abbreviation does not need to be emitted.
</p>

<div class="doc_text">
<p><tt>[DEFINE_ABBREV, numabbrevops<sub>vbr5</sub>, abbrevop0, abbrevop1,
...]</tt></p>
<p>An abbreviation definition consists of the DEFINE_ABBREV abbrevid followed
by a VBR that specifies the number of abbrev operands, then the abbrev
operands themselves. Abbreviation operands come in three forms. They all start
with a single bit that indicates whether the abbrev operand is a literal operand
(when the bit is 1) or an encoding operand (when the bit is 0).</p>
<ol>
<li>Literal operands - <tt>[1<sub>1</sub>, litvalue<sub>vbr8</sub>]</tt> -
Literal operands specify that the value in the result
is always a single specific value. This specific value is emitted as a vbr8
after the bit indicating that it is a literal operand.</li>
<li>Encoding info without data - <tt>[0<sub>1</sub>, encoding<sub>3</sub>]</tt>
- Operand encodings that do not have extra data are just emitted as their code.
</li>
<li>Encoding info with data - <tt>[0<sub>1</sub>, encoding<sub>3</sub>,
value<sub>vbr5</sub>]</tt> - Operand encodings that do have extra data are
emitted as their code, followed by the extra data.
</li>
</ol>
<p>The possible operand encodings are:</p>
<ul>
<li>1 - Fixed - The field should be emitted as a <a
href="#fixedwidth">fixed-width value</a>, whose width
is specified by the encoding operand.</li>
<li>2 - VBR - The field should be emitted as a <a
href="#variablewidth">variable-width value</a>, whose width
is specified by the encoding operand.</li>
<li>3 - Array - This field is an array of values. The element type of the array
is specified by the next encoding operand.</li>
<li>4 - Char6 - This field should be emitted as a <a href="#char6">char6-encoded
value</a>.</li>
</ul>
<p>For example, target triples in LLVM modules are encoded as a record of the
form <tt>[TRIPLE, 'a', 'b', 'c', 'd']</tt>. Consider if the bitstream emitted
the following abbrev entry:</p>
<ul>
<li><tt>[0, Fixed, 4]</tt></li>
<li><tt>[0, Array]</tt></li>
<li><tt>[0, Char6]</tt></li>
</ul>
<p>When emitting a record with this abbreviation, the above entry would be
emitted as:</p>
<p><tt>[4<sub>abbrevwidth</sub>, 2<sub>4</sub>, 4<sub>vbr6</sub>,
0<sub>6</sub>, 1<sub>6</sub>, 2<sub>6</sub>, 3<sub>6</sub>]</tt></p>
<p>These values are:</p>
<ol>
<li>The first value, 4, is the abbreviation ID for this abbreviation.</li>
<li>The second value, 2, is the code for TRIPLE in LLVM IR files.</li>
<li>The third value, 4, is the length of the array.</li>
<li>The rest of the values are the char6 encoded values for "abcd".</li>
</ol>
<p>With this abbreviation, the triple is emitted with only 37 bits (assuming a
abbrev id width of 3). Without the abbreviation, significantly more space would
be required to emit the target triple. Also, since the TRIPLE value is not
emitted as a literal in the abbreviation, the abbreviation can also be used for
any other string value.

records for things like instructions, global variable descriptors, type
descriptions, etc. This document does not describe the set of abbreviations
that the writer uses, as these are fully self-described in the file, and the
reader is not allowed to build in any knowledge of this.</p>

.IX Title "BUGPOINT 1"
.TH BUGPOINT 1 "2006-09-13" "CVS" "LLVM Command Guide"
.SH "NAME"
bugpoint \- automatic test case reduction tool
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBbugpoint\fR [\fIoptions\fR] [\fIinput \s-1LLVM\s0 ll/bc files\fR] [\fI\s-1LLVM\s0 passes\fR] \fB\-\-args\fR
\&\fIprogram arguments\fR
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBbugpoint\fR narrows down the source of problems in \s-1LLVM\s0 tools and passes. It
can be used to debug three types of failures: optimizer crashes, miscompilations
by optimizers, or bad native code generation (including problems in the static
and \s-1JIT\s0 compilers). It aims to reduce large test cases to small, useful ones.
For more information on the design and inner workings of \fBbugpoint\fR, as well as
advice for using bugpoint, see \fIllvm/docs/Bugpoint.html\fR in the \s-1LLVM\s0
distribution.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-\-additional\-so\fR \fIlibrary\fR" 4
.IX Item "--additional-so library"
Load the dynamic shared object \fIlibrary\fR into the test program whenever it is
run. This is useful if you are debugging programs which depend on non-LLVM
libraries (such as the X or curses libraries) to run.
.IP "\fB\-\-args\fR \fIprogram args\fR" 4
.IX Item "--args program args"
Pass all arguments specified after \-args to the test program whenever it runs.
Note that if any of the \fIprogram args\fR start with a '\-', you should use:
.Sp
.Vb 1
\& bugpoint [bugpoint args] --args -- [program args]
.Ve
.Sp
The \*(L"\-\-\*(R" right after the \fB\-\-args\fR option tells \fBbugpoint\fR to consider any
options starting with \f(CW\*(C`\-\*(C'\fR to be part of the \fB\-\-args\fR option, not as options to
\&\fBbugpoint\fR itself.
.IP "\fB\-\-tool\-args\fR \fItool args\fR" 4
.IX Item "--tool-args tool args"
Pass all arguments specified after \-\-tool\-args to the \s-1LLVM\s0 tool under test
(\fBllc\fR, \fBlli\fR, etc.) whenever it runs. You should use this option in the
following way:
.Sp
.Vb 1
\& bugpoint [bugpoint args] --tool-args -- [tool args]
.Ve
.Sp
The \*(L"\-\-\*(R" right after the \fB\-\-tool\-args\fR option tells \fBbugpoint\fR to consider any
options starting with \f(CW\*(C`\-\*(C'\fR to be part of the \fB\-\-tool\-args\fR option, not as
options to \fBbugpoint\fR itself. (See \fB\-\-args\fR, above.)
.IP "\fB\-\-check\-exit\-code\fR=\fI{true,false}\fR" 4
.IX Item "--check-exit-code={true,false}"
Assume a non-zero exit code or core dump from the test program is a failure.
Defaults to true.
.IP "\fB\-\-disable\-{dce,simplifycfg}\fR" 4
.IX Item "--disable-{dce,simplifycfg}"
Do not run the specified passes to clean up and reduce the size of the test
program. By default, \fBbugpoint\fR uses these passes internally when attempting to
reduce test programs. If you're trying to find a bug in one of these passes,
\&\fBbugpoint\fR may crash.
.IP "\fB\-find\-bugs\fR" 4
.IX Item "-find-bugs"
Continually randomize the specified passes and run them on the test program
until a bug is found or the user kills \fBbugpoint\fR.
.IP "\fB\-\-help\fR" 4
.IX Item "--help"
Print a summary of command line options.
.IP "\fB\-\-input\fR \fIfilename\fR" 4
.IX Item "--input filename"
Open \fIfilename\fR and redirect the standard input of the test program, whenever
it runs, to come from that file.
.IP "\fB\-\-load\fR \fIplugin\fR" 4
.IX Item "--load plugin"
Load the dynamic object \fIplugin\fR into \fBbugpoint\fR itself. This object should
register new optimization passes. Once loaded, the object will add new command
line options to enable various optimizations. To see the new complete list of
optimizations, use the \fB\-\-help\fR and \fB\-\-load\fR options together; for example:
.Sp
.Vb 1
\& bugpoint --load myNewPass.so --help
.Ve
.IP "\fB\-\-output\fR \fIfilename\fR" 4
.IX Item "--output filename"
Whenever the test program produces output on its standard output stream, it
should match the contents of \fIfilename\fR (the \*(L"reference output\*(R"). If you
do not use this option, \fBbugpoint\fR will attempt to generate a reference output
by compiling the program with the C backend and running it.
.IP "\fB\-\-profile\-info\-file\fR \fIfilename\fR" 4
.IX Item "--profile-info-file filename"
Profile file loaded by \fB\-\-profile\-loader\fR.
.IP "\fB\-\-run\-{int,jit,llc,cbe}\fR" 4
.IX Item "--run-{int,jit,llc,cbe}"
Whenever the test program is compiled, \fBbugpoint\fR should generate code for it
using the specified code generator. These options allow you to choose the
interpreter, the \s-1JIT\s0 compiler, the static native code compiler, or the C
backend, respectively.
.IP "\fB\-\-enable\-valgrind\fR" 4
.IX Item "--enable-valgrind"
Use valgrind to find faults in the optimization phase. This will allow
bugpoint to find otherwise asymptomatic problems caused by memory
mis\-management.
.SH "EXIT STATUS"
.IX Header "EXIT STATUS"
If \fBbugpoint\fR succeeds in finding a problem, it will exit with 0. Otherwise,
if an error occurs, it will exit with a non-zero value.
.SH "SEE ALSO"
.IX Header "SEE ALSO"
opt
.SH "AUTHOR"
.IX Header "AUTHOR"

.IX Title "LLC 1"
.TH LLC 1 "2006-03-13" "CVS" "LLVM Command Guide"
.SH "NAME"
llc \- LLVM static compiler
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBllc\fR [\fIoptions\fR] [\fIfilename\fR]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBllc\fR command compiles \s-1LLVM\s0 bytecode into assembly language for a
specified architecture. The assembly language output can then be passed through
a native assembler and linker to generate a native executable.
.PP
The choice of architecture for the output assembly code is automatically
determined from the input bytecode file, unless the \fB\-march\fR option is used to
override the default.
.SH "OPTIONS"
.IX Header "OPTIONS"
If \fIfilename\fR is \- or omitted, \fBllc\fR reads \s-1LLVM\s0 bytecode from standard input.
Otherwise, it will read \s-1LLVM\s0 bytecode from \fIfilename\fR.
.PP
If the \fB\-o\fR option is omitted, then \fBllc\fR will send its output to standard
output if the input is from standard input. If the \fB\-o\fR option specifies \-,
then the output will also be sent to standard output.
.PP
If no \fB\-o\fR option is specified and an input file other than \- is specified,
then \fBllc\fR creates the output filename by taking the input filename,
removing any existing \fI.bc\fR extension, and adding a \fI.s\fR suffix.
.PP
Other \fBllc\fR options are as follows:
.Sh "End-user Options"
.IX Subsection "End-user Options"
.IP "\fB\-\-help\fR" 4
.IX Item "--help"
Print a summary of command line options.
.IP "\fB\-f\fR" 4
.IX Item "-f"
Overwrite output files. By default, \fBllc\fR will refuse to overwrite
an output file which already exists.
.IP "\fB\-mtriple\fR=\fItarget triple\fR" 4
.IX Item "-mtriple=target triple"
Override the target triple specified in the input bytecode file with the
specified string.
.IP "\fB\-march\fR=\fIarch\fR" 4
.IX Item "-march=arch"
Specify the architecture for which to generate assembly, overriding the target
encoded in the bytecode file. See the output of \fBllc \-\-help\fR for a list of
valid architectures. By default this is inferred from the target triple or
autodetected to the current architecture.
.IP "\fB\-mcpu\fR=\fIcpuname\fR" 4
.IX Item "-mcpu=cpuname"
Specify a specific chip in the current architecture to generate code for.
By default this is inferred from the target triple and autodetected to
the current architecture. For a list of available CPUs, use:
\&\fBllvm-as < /dev/null | llc \-march=xyz \-mcpu=help\fR
.IP "\fB\-mattr\fR=\fIa1,+a2,\-a3,...\fR" 4
.IX Item "-mattr=a1,+a2,-a3,..."
Override or control specific attributes of the target, such as whether \s-1SIMD\s0
operations are enabled or not. The default set of attributes is set by the
current \s-1CPU\s0. For a list of available attributes, use:
\&\fBllvm-as < /dev/null | llc \-march=xyz \-mattr=help\fR
.IP "\fB\-\-disable\-fp\-elim\fR" 4
.IX Item "--disable-fp-elim"
Disable frame pointer elimination optimization.
.IP "\fB\-\-disable\-excess\-fp\-precision\fR" 4
.IX Item "--disable-excess-fp-precision"
Disable optimizations that may produce excess precision for floating point.
Note that this option can dramatically slow down code on some systems
(e.g. X86).
.IP "\fB\-\-enable\-unsafe\-fp\-math\fR" 4
.IX Item "--enable-unsafe-fp-math"
Enable optimizations that make unsafe assumptions about \s-1IEEE\s0 math (e.g. that
addition is associative) or may not work for all input ranges. These
optimizations allow the code generator to make use of some instructions which
would otherwise not be usable (such as fsin on X86).
.IP "\fB\-\-enable\-correct\-eh\-support\fR" 4
.IX Item "--enable-correct-eh-support"
Instruct the \fBlowerinvoke\fR pass to insert code for correct exception handling
support. This is expensive and is by default omitted for efficiency.
.IP "\fB\-\-stats\fR" 4
.IX Item "--stats"
Print statistics recorded by code-generation passes.
.IP "\fB\-\-time\-passes\fR" 4
.IX Item "--time-passes"
Record the amount of time needed for each pass and print a report to standard
error.
.IP "\fB\-\-load\fR=\fIdso_path\fR" 4
.IX Item "--load=dso_path"
Dynamically load \fIdso_path\fR (a path to a dynamically shared object) that
implements an \s-1LLVM\s0 target. This will permit the target name to be used with the
\&\fB\-march\fR option so that code can be generated for that target.
.Sh "Tuning/Configuration Options"
.IX Subsection "Tuning/Configuration Options"

\&\fBlli\fR directly executes programs in \s-1LLVM\s0 bytecode format. It takes a program
in \s-1LLVM\s0 bytecode format and executes it using a just-in-time compiler, if one is
available for the current architecture, or an interpreter. \fBlli\fR takes all of
the same code generator options as llc, but they are only effective when
\&\fBlli\fR is using the just-in-time compiler.
.PP
If \fIfilename\fR is not specified, then \fBlli\fR reads the \s-1LLVM\s0 bytecode for the
program from standard input.

.IX Title "LLVM-AR 1"
.TH LLVM-AR 1 "2006-11-20" "CVS" "LLVM Command Guide"
.SH "NAME"
llvm\-ar \- LLVM archiver
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBllvm-ar\fR [\-]{dmpqrtx}[Rabfikouz] [relpos] [count] <archive> [files...]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBllvm-ar\fR command is similar to the common Unix utility, \f(CW\*(C`ar\*(C'\fR. It
archives several files together into a single file. The intent for this is
to produce archive libraries by \s-1LLVM\s0 bytecode that can be linked into an
\&\s-1LLVM\s0 program. However, the archive can contain any kind of file. By default,
\&\fBllvm-ar\fR generates a symbol table that makes linking faster because
only the symbol table needs to be consulted, not each individual file member
of the archive.
.PP
The \fBllvm-ar\fR command can be used to \fIread\fR both \s-1SVR4\s0 and \s-1BSD\s0 style archive
files. However, it cannot be used to write them. While the \fBllvm-ar\fR command
produces files that are \fIalmost\fR identical to the format used by other \f(CW\*(C`ar\*(C'\fR
implementations, it has two significant departures in order to make the
archive appropriate for \s-1LLVM\s0. The first departure is that \fBllvm-ar\fR only
uses \s-1BSD4\s0.4 style long path names (stored immediately after the header) and
never contains a string table for long names. The second departure is that the
symbol table is formated for efficient construction of an in-memory data
structure that permits rapid (red\-black tree) lookups. Consequently, archives
produced with \fBllvm-ar\fR usually won't be readable or editable with any
\&\f(CW\*(C`ar\*(C'\fR implementation or useful for linking. Using the \f(CW\*(C`f\*(C'\fR modifier to flatten
file names will make the archive readable by other \f(CW\*(C`ar\*(C'\fR implementations
but not for linking because the symbol table format for \s-1LLVM\s0 is unique. If an
\&\s-1SVR4\s0 or \s-1BSD\s0 style archive is used with the \f(CW\*(C`r\*(C'\fR (replace) or \f(CW\*(C`q\*(C'\fR (quick
update) operations, the archive will be reconstructed in \s-1LLVM\s0 format. This
means that the string table will be dropped (in deference to \s-1BSD\s0 4.4 long names)
and an \s-1LLVM\s0 symbol table will be added (by default). The system symbol table
will be retained.
.PP
Here's where \fBllvm-ar\fR departs from previous \f(CW\*(C`ar\*(C'\fR implementations:
.IP "\fISymbol Table\fR" 4
.IX Item "Symbol Table"
Since \fBllvm-ar\fR is intended to archive bytecode files, the symbol table
won't make much sense to anything but \s-1LLVM\s0. Consequently, the symbol table's
format has been simplified. It consists simply of a sequence of pairs
of a file member index number as an \s-1LSB\s0 4byte integer and a null-terminated
string.
.IP "\fILong Paths\fR" 4
.IX Item "Long Paths"
Some \f(CW\*(C`ar\*(C'\fR implementations (\s-1SVR4\s0) use a separate file member to record long
path names (> 15 characters). \fBllvm-ar\fR takes the \s-1BSD\s0 4.4 and Mac \s-1OS\s0 X
approach which is to simply store the full path name immediately preceding
the data for the file. The path name is null terminated and may contain the
slash (/) character.
.IP "\fICompression\fR" 4
.IX Item "Compression"
\&\fBllvm-ar\fR can compress the members of an archive to save space. The
compression used depends on what's available on the platform and what choices
the \s-1LLVM\s0 Compressor utility makes. It generally favors bzip2 but will select
between \*(L"no compression\*(R" or bzip2 depending on what makes sense for the
file's content.
.IP "\fIDirectory Recursion\fR" 4
.IX Item "Directory Recursion"
Most \f(CW\*(C`ar\*(C'\fR implementations do not recurse through directories but simply
ignore directories if they are presented to the program in the \fIfiles\fR
option. \fBllvm-ar\fR, however, can recurse through directory structures and
add all the files under a directory, if requested.
.IP "\fI\s-1TOC\s0 Verbose Output\fR" 4
.IX Item "TOC Verbose Output"
When \fBllvm-ar\fR prints out the verbose table of contents (\f(CW\*(C`tv\*(C'\fR option), it
precedes the usual output with a character indicating the basic kind of
content in the file. A blank means the file is a regular file. A 'Z' means
the file is compressed. A 'B' means the file is an \s-1LLVM\s0 bytecode file. An
\&'S' means the file is the symbol table.
.SH "OPTIONS"
.IX Header "OPTIONS"
The options to \fBllvm-ar\fR are compatible with other \f(CW\*(C`ar\*(C'\fR implementations.
However, there are a few modifiers (\fIzR\fR) that are not found in other
\&\f(CW\*(C`ar\*(C'\fRs. The options to \fBllvm-ar\fR specify a single basic operation to
perform on the archive, a variety of modifiers for that operation, the
name of the archive file, and an optional list of file names. These options
are used to determine how \fBllvm-ar\fR should process the archive file.
.PP
The Operations and Modifiers are explained in the sections below. The minimal
set of options is at least one operator and the name of the archive. Typically
archive files end with a \f(CW\*(C`.a\*(C'\fR suffix, but this is not required. Following
the \fIarchive-name\fR comes a list of \fIfiles\fR that indicate the specific members
of the archive to operate on. If the \fIfiles\fR option is not specified, it
generally means either \*(L"none\*(R" or \*(L"all\*(R" members, depending on the operation.
.Sh "Operations"
.IX Subsection "Operations"
.IP "d" 4
.IX Item "d"
Delete files from the archive. No modifiers are applicable to this operation.
The \fIfiles\fR options specify which members should be removed from the
archive. It is not an error if a specified file does not appear in the archive.
If no \fIfiles\fR are specified, the archive is not modified.
.IP "m[abi]" 4
.IX Item "m[abi]"
Move files from one location in the archive to another. The \fIa\fR, \fIb\fR, and
\&\fIi\fR modifiers apply to this operation. The \fIfiles\fR will all be moved
to the location given by the modifiers. If no modifiers are used, the files
will be moved to the end of the archive. If no \fIfiles\fR are specified, the
archive is not modified.
.IP "p[k]" 4
.IX Item "p[k]"
Print files to the standard output. The \fIk\fR modifier applies to this
operation. This operation simply prints the \fIfiles\fR indicated to the
standard output. If no \fIfiles\fR are specified, the entire archive is printed.
Printing bytecode files is ill-advised as they might confuse your terminal
settings. The \fIp\fR operation never modifies the archive.
.IP "q[Rfz]" 4
.IX Item "q[Rfz]"
Quickly append files to the end of the archive. The \fIR\fR, \fIf\fR, and \fIz\fR
modifiers apply to this operation. This operation quickly adds the
\&\fIfiles\fR to the archive without checking for duplicates that should be
removed first. If no \fIfiles\fR are specified, the archive is not modified.
Because of the way that \fBllvm-ar\fR constructs the archive file, its dubious
whether the \fIq\fR operation is any faster than the \fIr\fR operation.
.IP "r[Rabfuz]" 4
.IX Item "r[Rabfuz]"
Replace or insert file members. The \fIR\fR, \fIa\fR, \fIb\fR, \fIf\fR, \fIu\fR, and \fIz\fR
modifiers apply to this operation. This operation will replace existing
\&\fIfiles\fR or insert them at the end of the archive if they do not exist. If no
\&\fIfiles\fR are specified, the archive is not modified.
.IP "t[v]" 4
.IX Item "t[v]"
Print the table of contents. Without any modifiers, this operation just prints
the names of the members to the standard output. With the \fIv\fR modifier,
\&\fBllvm-ar\fR also prints out the file type (B=bytecode, Z=compressed, S=symbol
table, blank=regular file), the permission mode, the owner and group, the
size, and the date. If any \fIfiles\fR are specified, the listing is only for
those files. If no \fIfiles\fR are specified, the table of contents for the
whole archive is printed.
.IP "x[oP]" 4
.IX Item "x[oP]"
Extract archive members back to files. The \fIo\fR modifier applies to this
operation. This operation retrieves the indicated \fIfiles\fR from the archive
and writes them back to the operating system's file system. If no
\&\fIfiles\fR are specified, the entire archive is extract.
.Sh "Modifiers (operation specific)"
.IX Subsection "Modifiers (operation specific)"
The modifiers below are specific to certain operations. See the Operations
section (above) to determine which modifiers are applicable to which operations.
.IP "[a]" 4
.IX Item "[a]"
When inserting or moving member files, this option specifies the destination of
the new files as being \f(CW\*(C`a\*(C'\fRfter the \fIrelpos\fR member. If \fIrelpos\fR is not found,
the files are placed at the end of the archive.
.IP "[b]" 4
.IX Item "[b]"
When inserting or moving member files, this option specifies the destination of
the new files as being \f(CW\*(C`b\*(C'\fRefore the \fIrelpos\fR member. If \fIrelpos\fR is not
found, the files are placed at the end of the archive. This modifier is
identical to the the \fIi\fR modifier.
.IP "[f]" 4
.IX Item "[f]"
Normally, \fBllvm-ar\fR stores the full path name to a file as presented to it on
the command line. With this option, truncated (15 characters max) names are
used. This ensures name compatibility with older versions of \f(CW\*(C`ar\*(C'\fR but may also
thwart correct extraction of the files (duplicates may overwrite). If used with
the \fIR\fR option, the directory recursion will be performed but the file names
will all be \f(CW\*(C`f\*(C'\fRlattened to simple file names.
.IP "[i]" 4
.IX Item "[i]"
A synonym for the \fIb\fR option.
.IP "[k]" 4
.IX Item "[k]"
Normally, \fBllvm-ar\fR will not print the contents of bytecode files when the
\&\fIp\fR operation is used. This modifier defeats the default and allows the
bytecode members to be printed.
.IP "[N]" 4
.IX Item "[N]"
This option is ignored by \fBllvm-ar\fR but provided for compatibility.
.IP "[o]" 4
.IX Item "[o]"
When extracting files, this option will cause \fBllvm-ar\fR to preserve the
original modification times of the files it writes.
.IP "[P]" 4
.IX Item "[P]"
use full path names when matching
.IP "[R]" 4
.IX Item "[R]"
This modifier instructions the \fIr\fR option to recursively process directories.
Without \fIR\fR, directories are ignored and only those \fIfiles\fR that refer to
files will be added to the archive. When \fIR\fR is used, any directories specified
with \fIfiles\fR will be scanned (recursively) to find files to be added to the
archive. Any file whose name begins with a dot will not be added.
.IP "[u]" 4
.IX Item "[u]"
When replacing existing files in the archive, only replace those files that have
a time stamp than the time stamp of the member in the archive.
.IP "[z]" 4
.IX Item "[z]"
When inserting or replacing any file in the archive, compress the file first.
This
modifier is safe to use when (previously) compressed bytecode files are added to
the archive; the compressed bytecode files will not be doubly compressed.
.Sh "Modifiers (generic)"
.IX Subsection "Modifiers (generic)"
The modifiers below may be applied to any operation.
.IP "[c]" 4
.IX Item "[c]"
For all operations, \fBllvm-ar\fR will always create the archive if it doesn't
exist. Normally, \fBllvm-ar\fR will print a warning message indicating that the
archive is being created. Using this modifier turns off that warning.
.IP "[s]" 4
.IX Item "[s]"
This modifier requests that an archive index (or symbol table) be added to the
archive. This is the default mode of operation. The symbol table will contain
all the externally visible functions and global variables defined by all the
bytecode files in the archive. Using this modifier is more efficient that using
llvm-ranlib which also creates the symbol table.
.IP "[S]" 4
.IX Item "[S]"
This modifier is the opposite of the \fIs\fR modifier. It instructs \fBllvm-ar\fR to
not build the symbol table. If both \fIs\fR and \fIS\fR are used, the last modifier to
occur in the options will prevail.
.IP "[v]" 4
.IX Item "[v]"
This modifier instructs \fBllvm-ar\fR to be verbose about what it is doing. Each
editing operation taken against the archive will produce a line of output saying
what is being done.
.SH "STANDARDS"
.IX Header "STANDARDS"
The \fBllvm-ar\fR utility is intended to provide a superset of the \s-1IEEE\s0 Std 1003.2
(\s-1POSIX\s0.2) functionality for \f(CW\*(C`ar\*(C'\fR. \fBllvm-ar\fR can read both \s-1SVR4\s0 and \s-1BSD4\s0.4 (or
Mac \s-1OS\s0 X) archives. If the \f(CW\*(C`f\*(C'\fR modifier is given to the \f(CW\*(C`x\*(C'\fR or \f(CW\*(C`r\*(C'\fR operations
then \fBllvm-ar\fR will write \s-1SVR4\s0 compatible archives. Without this modifier,
\&\fBllvm-ar\fR will write \s-1BSD4\s0.4 compatible archives that have long names
immediately after the header and indicated using the \*(L"#1/ddd\*(R" notation for the
name in the header.
.SH "FILE FORMAT"
.IX Header "FILE FORMAT"
The file format for \s-1LLVM\s0 Archive files is similar to that of \s-1BSD\s0 4.4 or Mac \s-1OSX\s0
archive files. In fact, except for the symbol table, the \f(CW\*(C`ar\*(C'\fR commands on those
operating systems should be able to read \s-1LLVM\s0 archive files. The details of the
file format follow.
.PP
Each archive begins with the archive magic number which is the eight printable
characters \*(L"!<arch>\en\*(R" where \en represents the newline character (0x0A).
Following the magic number, the file is composed of even length members that
begin with an archive header and end with a \en padding character if necessary
(to make the length even). Each file member is composed of a header (defined
below), an optional newline-terminated \*(L"long file name\*(R" and the contents of
the file.
.PP
The fields of the header are described in the items below. All fields of the
header contain only \s-1ASCII\s0 characters, are left justified and are right padded
with space characters.
.IP "name \- char[16]" 4
.IX Item "name - char[16]"
This field of the header provides the name of the archive member. If the name is
longer than 15 characters or contains a slash (/) character, then this field
contains \f(CW\*(C`#1/nnn\*(C'\fR where \f(CW\*(C`nnn\*(C'\fR provides the length of the name and the \f(CW\*(C`#1/\*(C'\fR
is literal. In this case, the actual name of the file is provided in the \f(CW\*(C`nnn\*(C'\fR
bytes immediately following the header. If the name is 15 characters or less, it
is contained directly in this field and terminated with a slash (/) character.
.IP "date \- char[12]" 4
.IX Item "date - char[12]"
This field provides the date of modification of the file in the form of a
decimal encoded number that provides the number of seconds since the epoch
(since 00:00:00 Jan 1, 1970) per Posix specifications.
.IP "uid \- char[6]" 4
.IX Item "uid - char[6]"
This field provides the user id of the file encoded as a decimal \s-1ASCII\s0 string.
This field might not make much sense on non-Unix systems. On Unix, it is the
same value as the st_uid field of the stat structure returned by the \fIstat\fR\|(2)
operating system call.
.IP "gid \- char[6]" 4
.IX Item "gid - char[6]"
This field provides the group id of the file encoded as a decimal \s-1ASCII\s0 string.
This field might not make much sense on non-Unix systems. On Unix, it is the
same value as the st_gid field of the stat structure returned by the \fIstat\fR\|(2)
operating system call.
.IP "mode \- char[8]" 4
.IX Item "mode - char[8]"
This field provides the access mode of the file encoded as an octal \s-1ASCII\s0
string. This field might not make much sense on non-Unix systems. On Unix, it
is the same value as the st_mode field of the stat structure returned by the
\&\fIstat\fR\|(2) operating system call.
.IP "size \- char[10]" 4
.IX Item "size - char[10]"
This field provides the size of the file, in bytes, encoded as a decimal \s-1ASCII\s0
string. If the size field is negative (starts with a minus sign, 0x02D), then
the archive member is stored in compressed form. The first byte of the archive
member's data indicates the compression type used. A value of 0 (0x30) indicates
that no compression was used. A value of 2 (0x32) indicates that bzip2
compression was used.
.IP "fmag \- char[2]" 4
.IX Item "fmag - char[2]"
This field is the archive file member magic number. Its content is always the
two characters back tick (0x60) and newline (0x0A). This provides some measure
utility in identifying archive files that have been corrupted.
.PP
The \s-1LLVM\s0 symbol table has the special name \*(L"#_LLVM_SYM_TAB_#\*(R". It is presumed
that no regular archive member file will want this name. The \s-1LLVM\s0 symbol table
is simply composed of a sequence of triplets: byte offset, length of symbol,
and the symbol itself. Symbols are not null or newline terminated. Here are
the details on each of these items:
.IP "offset \- vbr encoded 32\-bit integer" 4
.IX Item "offset - vbr encoded 32-bit integer"
The offset item provides the offset into the archive file where the bytecode
member is stored that is associated with the symbol. The offset value is 0
based at the start of the first \*(L"normal\*(R" file member. To derive the actual
file offset of the member, you must add the number of bytes occupied by the file
signature (8 bytes) and the symbol tables. The value of this item is encoded
using variable bit rate encoding to reduce the size of the symbol table.
Variable bit rate encoding uses the high bit (0x80) of each byte to indicate
if there are more bytes to follow. The remaining 7 bits in each byte carry bits
from the value. The final byte does not have the high bit set.
.IP "length \- vbr encoded 32\-bit integer" 4
.IX Item "length - vbr encoded 32-bit integer"
The length item provides the length of the symbol that follows. Like this
\&\fIoffset\fR item, the length is variable bit rate encoded.
.IP "symbol \- character array" 4
.IX Item "symbol - character array"
The symbol item provides the text of the symbol that is associated with the
\&\fIoffset\fR. The symbol is not terminated by any character. Its length is provided
by the \fIlength\fR field. Note that is allowed (but unwise) to use non-printing
characters (even 0x00) in the symbol. This allows for multiple encodings of
symbol names.
.SH "EXIT STATUS"
.IX Header "EXIT STATUS"
If \fBllvm-ar\fR succeeds, it will exit with 0. A usage error, results
in an exit code of 1. A hard (file system typically) error results in an
exit code of 2. Miscellaneous or unknown errors result in an
exit code of 3.
.SH "SEE ALSO"
.IX Header "SEE ALSO"

.IX Header "AUTHORS"

.IX Header "DESCRIPTION"
\&\fBllvm-as\fR is the \s-1LLVM\s0 assembler. It reads a file containing human-readable
\&\s-1LLVM\s0 assembly language, translates it to \s-1LLVM\s0 bytecode, and writes the result
into a file or to standard output.
.PP
If \fIfilename\fR is omitted or is \f(CW\*(C`\-\*(C'\fR, then \fBllvm-as\fR reads its input from
standard input.
.PP
If an output file is not specified with the \fB\-o\fR option, then
\&\fBllvm-as\fR sends its output to a file or standard output by following
these rules:
.IP "\(bu" 4
If the input is standard input, then the output is standard output.
.IP "\(bu" 4
If the input is a file that ends with \f(CW\*(C`.ll\*(C'\fR, then the output file is of
the same name, except that the suffix is changed to \f(CW\*(C`.bc\*(C'\fR.
.IP "\(bu" 4
If the input is a file that does not end with the \f(CW\*(C`.ll\*(C'\fR suffix, then the
output file has the same name as the input file, except that the \f(CW\*(C`.bc\*(C'\fR
suffix is appended.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-f\fR" 4
.IX Item "-f"
Force overwrite. Normally, \fBllvm-as\fR will refuse to overwrite an

.IX Header "SYNOPSIS"
\&\fBllvm-bcanalyzer\fR [\fIoptions\fR] [\fIfilename\fR]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBllvm-bcanalyzer\fR command is a small utility for analyzing bytecode files.
The tool reads a bytecode file (such as generated with the \fBllvm-as\fR tool) and
produces a statistical report on the contents of the byteocde file. The tool
can also dump a low level but human readable version of the bytecode file.
This tool is probably not of much interest or utility except for those working
directly with the bytecode file format. Most \s-1LLVM\s0 users can just ignore
this tool.
.PP
If \fIfilename\fR is omitted or is \f(CW\*(C`\-\*(C'\fR, then \fBllvm-bcanalyzer\fR reads its input
from standard input. This is useful for combining the tool into a pipeline.
Output is written to the standard output.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-nodetails\fR" 4

Causes \fBllvm-bcanalyzer\fR to abbreviate its output by writing out only a module
level summary. The details for individual functions are not displayed.
.IP "\fB\-dump\fR" 4

.IX Header "DESCRIPTION"
The \fBllvm-dis\fR command is the \s-1LLVM\s0 disassembler. It takes an \s-1LLVM\s0
bytecode file and converts it into human-readable \s-1LLVM\s0 assembly language.
.PP
If filename is omitted or specified as \f(CW\*(C`\-\*(C'\fR, \fBllvm-dis\fR reads its
input from standard input.
.PP
If the input is being read from standard input, then \fBllvm-dis\fR
will send its output to standard output by default. Otherwise, the
output will be written to a file named after the input file, with
a \f(CW\*(C`.ll\*(C'\fR suffix added (any existing \f(CW\*(C`.bc\*(C'\fR suffix will first be
removed). You can override the choice of output file using the
\&\fB\-o\fR option.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-f\fR" 4
.IX Item "-f"
Force overwrite. Normally, \fBllvm-dis\fR will refuse to overwrite
an output file that already exists. With this option, \fBllvm-dis\fR
will overwrite the output file.
.IP "\fB\-\-help\fR" 4
.IX Item "--help"
Print a summary of command line options.
.IP "\fB\-o\fR \fIfilename\fR" 4
.IX Item "-o filename"
Specify the output file name. If \fIfilename\fR is \-, then the output is sent
to standard output.

.IX Title "LLVM-LD 1"
.TH LLVM-LD 1 "2007-05-06" "CVS" "LLVM Command Guide"
.SH "NAME"
llvm\-ld \- LLVM linker
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBllvm-ld\fR <options> <files>
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBllvm-ld\fR tool takes a set of \s-1LLVM\s0 bytecode files and links them
together into a single \s-1LLVM\s0 bytecode file. The output bytecode file can be
another bytecode file or an executable bytecode program. Using additional
options, \fBllvm-ld\fR is able to produce native code executables.
.PP
The \fBllvm-ld\fR tool is the main linker for \s-1LLVM\s0. It is used to link together
the output of \s-1LLVM\s0 front-end compilers and run \*(L"link time\*(R" optimizations (mostly
the inter-procedural kind).
.PP
The \fBllvm-ld\fR tools attemps to mimic the interface provided by the default
system linker so that it can act as a \fIdrop-in\fR replacement.
.Sh "Search Order"
.IX Subsection "Search Order"
When looking for objects specified on the command line, \fBllvm-ld\fR will search
for the object first in the current directory and then in the directory
specified by the \fB\s-1LLVM_LIB_SEARCH_PATH\s0\fR environment variable. If it cannot
find the object, it fails.
.PP
When looking for a library specified with the \fB\-l\fR option, \fBllvm-ld\fR first
attempts to load a file with that name from the current directory. If that
fails, it looks for lib\fIlibrary\fR.bc, lib\fIlibrary\fR.a, or lib\fIlibrary\fR.\fIshared
library extension\fR, in that order, in each directory added to the library search
path with the \fB\-L\fR option. These directories are searched in the order they
are specified. If the library cannot be located, then \fBllvm-ld\fR looks in the
directory specified by the \fB\s-1LLVM_LIB_SEARCH_PATH\s0\fR environment variable. If it
does not find a library there, it fails.
.PP
The \fIshared library extension\fR may be \fI.so\fR, \fI.dyld\fR, \fI.dll\fR, or something
different, depending upon the system.
.PP
The \fB\-L\fR option is global. It does not matter where it is specified in the
list of command line arguments; the directory is simply added to the search path
and is applied to all libraries, preceding or succeeding, in the command line.
.Sh "Link order"
.IX Subsection "Link order"
All object and bytecode files are linked first in the order they were
specified on the command line. All library files are linked next.
Some libraries may not be linked into the object program; see below.
.Sh "Library Linkage"
.IX Subsection "Library Linkage"
Object files and static bytecode objects are always linked into the output
file. Library archives (.a files) load only the objects within the archive
that define symbols needed by the output file. Hence, libraries should be
listed after the object files and libraries which need them; otherwise, the
library may not be linked in, and the dependent library will not have its
undefined symbols defined.
.Sh "Native code generation"
.IX Subsection "Native code generation"
The \fBllvm-ld\fR program has limited support for native code generation, when
using the \fB\-native\fR or \fB\-native\-cbe\fR options. Native code generation is
perfomed by converting the linked bytecode into native assembly (.s) or C code
and running the system compiler (typically gcc) on the result.
.SH "OPTIONS"
.IX Header "OPTIONS"
.Sh "General Options"
.IX Subsection "General Options"
.IP "\fB\-help\fR" 4
.IX Item "-help"
Print a summary of command line options.
.IP "\fB\-v\fR" 4
.IX Item "-v"
Specifies verbose mode. In this mode the linker will print additional
information about the actions it takes, programs it executes, etc.
.IP "\fB\-stats\fR" 4
.IX Item "-stats"
Print statistics.
.IP "\fB\-time\-passes\fR" 4
.IX Item "-time-passes"
Record the amount of time needed for each pass and print it to standard
error.
.Sh "Input/Output Options"
.IX Subsection "Input/Output Options"
.IP "\fB\-o\fR \fIfilename\fR" 4
.IX Item "-o filename"
This overrides the default output file and specifies the name of the file that
should be generated by the linker. By default, \fBllvm-ld\fR generates a file named
\&\fIa.out\fR for compatibility with \fBld\fR. The output will be written to
\&\fIfilename\fR.
.IP "\fB\-l\fR\fIname\fR" 4
.IX Item "-lname"
This option specifies the \fIname\fR of a library to search when resolving symbols
for the program. Only the base name should be specified as \fIname\fR, without a
\&\fIlib\fR prefix or any suffix.
.IP "\fB\-L\fR\fIPath\fR" 4
.IX Item "-LPath"
This option tells \fBllvm-ld\fR to look in \fIPath\fR to find any library subsequently
specified with the \fB\-l\fR option. The paths will be searched in the order in
which they are specified on the command line. If the library is still not found,
a small set of system specific directories will also be searched. Note that
libraries specified with the \fB\-l\fR option that occur \fIbefore\fR any \fB\-L\fR options
will not search the paths given by the \fB\-L\fR options following it.
.IP "\fB\-link\-as\-library\fR" 4
.IX Item "-link-as-library"
Link the bytecode files together as a library, not an executable. In this mode,
undefined symbols will be permitted.
.IP "\fB\-r\fR" 4
.IX Item "-r"
An alias for \-link\-as\-library.
.ie n .IP "\fB\-march=\fR""target""" 4
.el .IP "\fB\-march=\fR\f(CWtarget\fR" 4
.IX Item "-march=target"
Specifies the kind of machine for which code or assembly should be generated.
.IP "\fB\-native\fR" 4
.IX Item "-native"
Generate a native machine code executable.
.Sp
When generating native executables, \fBllvm-ld\fR first checks for a bytecode
version of the library and links it in, if necessary. If the library is
missing, \fBllvm-ld\fR skips it. Then, \fBllvm-ld\fR links in the same
libraries as native code.
.Sp
In this way, \fBllvm-ld\fR should be able to link in optimized bytecode
subsets of common libraries and then link in any part of the library that
hasn't been converted to bytecode.
.IP "\fB\-native\-cbe\fR" 4
.IX Item "-native-cbe"
Generate a native machine code executable with the \s-1LLVM\s0 C backend.
.Sp
This option is identical to the \fB\-native\fR option, but uses the
C backend to generate code for the program instead of an \s-1LLVM\s0 native
code generator.
.Sh "Optimization Options"
.IX Subsection "Optimization Options"
.IP "\fB\-O0\fR" 4
.IX Item "-O0"
An alias for the \-O1 option.
.IP "\fB\-O1\fR" 4
.IX Item "-O1"
Optimize for linking speed, not execution speed. The optimizer will attempt to
reduce the size of the linked program to reduce I/O but will not otherwise
perform any link-time optimizations.
.IP "\fB\-O2\fR" 4
.IX Item "-O2"
Perform only the minimal or required set of scalar optimizations.
.IP "\fB\-03\fR" 4
.IX Item "-03"
An alias for the \-O2 option.
.IP "\fB\-04\fR" 4
.IX Item "-04"
Perform the standard link time inter-procedural optimizations. This will
attempt to optimize the program taking the entire program into consideration.
.IP "\fB\-O5\fR" 4
.IX Item "-O5"
Perform aggressive link time optimizations. This is the same as \-O4 but works
more aggressively to optimize the program.
.IP "\fB\-disable\-inlining\fR" 4
.IX Item "-disable-inlining"
Do not run the inlining pass. Functions will not be inlined into other
functions.
.IP "\fB\-disable\-opt\fR" 4
.IX Item "-disable-opt"
Completely disable optimization. The various \fB\-On\fR options will be ignored and
no link time optimization passes will be run.
.IP "\fB\-disable\-internalize\fR" 4
.IX Item "-disable-internalize"
Do not mark all symbols as internal.
.IP "\fB\-verify\-each\fR" 4
.IX Item "-verify-each"
Run the verification pass after each of the passes to verify intermediate
results.
.IP "\fB\-strip\-all\fR" 4
.IX Item "-strip-all"
Strip all debug and symbol information from the executable to make it smaller.
.IP "\fB\-strip\-debug\fR" 4
.IX Item "-strip-debug"
Strip all debug information from the executable to make it smaller.
.IP "\fB\-s\fR" 4
.IX Item "-s"
An alias for \fB\-strip\-all\fR.
.IP "\fB\-S\fR" 4
.IX Item "-S"
An alias for \fB\-strip\-debug\fR.
.IP "\fB\-export\-dynamic\fR" 4
.IX Item "-export-dynamic"
An alias for \fB\-disable\-internalize\fR
.IP "\fB\-load\fR \fImodule\fR" 4
.IX Item "-load module"
Load an optimization module, \fImodule\fR, which is expected to be a dynamic
library that provides the function name \f(CW\*(C`RunOptimizations\*(C'\fR. This function will
be passed the PassManager, and the optimization level (values 0\-5 based on the
\&\fB\-On\fR option). This function may add passes to the PassManager that should be
run. This feature allows the optimization passes of \fBllvm-ld\fR to be extended.
.IP "\fB\-post\-link\-opt\fR\fIPath\fR" 4
.IX Item "-post-link-optPath"
Run post-link optimization program. After linking is completed a bytecode file
will be generated. It will be passed to the program specified by \fIPath\fR as the
first argument. The second argument to the program will be the name of a
temporary file into which the program should place its optimized output. For
example, the \*(L"no\-op optimization\*(R" would be a simple shell script:
.Sp
.Vb 2
\& #!/bin/bash
\& cp $1 $2

.IX Header "EXIT STATUS"
If \fBllvm-ld\fR succeeds, it will exit with 0 return code. If an error occurs,
it will exit with a non-zero return code.
.SH "ENVIRONMENT"
.IX Header "ENVIRONMENT"
The \f(CW\*(C`LLVM_LIB_SEARCH_PATH\*(C'\fR environment variable is used to find bytecode
libraries. Any paths specified in this variable will be searched after the \f(CW\*(C`\-L\*(C'\fR
options.

llvm\-link \- LLVM linker
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBllvm-link\fR [\fIoptions\fR] \fIfilename ...\fR
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBllvm-link\fR takes several \s-1LLVM\s0 bytecode files and links them together into a
single \s-1LLVM\s0 bytecode file. It writes the output file to standard output, unless
the \fB\-o\fR option is used to specify a filename.
.PP
\&\fBllvm-link\fR attempts to load the input files from the current directory. If
that fails, it looks for each file in each of the directories specified by the
\&\fB\-L\fR options on the command line. The library search paths are global; each
one is searched for every input file if necessary. The directories are searched
in the order they were specified on the command line.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-L\fR \fIdirectory\fR" 4
.IX Item "-L directory"
Add the specified \fIdirectory\fR to the library search path. When looking for
libraries, \fBllvm-link\fR will look in pathname for libraries. This option can be
specified multiple times; \fBllvm-link\fR will search inside these directories in
the order in which they were specified on the command line.
.IP "\fB\-f\fR" 4
.IX Item "-f"
Overwrite output files. By default, \fBllvm-link\fR will not overwrite an output
file if it alreadys exists.
.IP "\fB\-o\fR \fIfilename\fR" 4
.IX Item "-o filename"
Specify the output file name. If \fIfilename\fR is \f(CW\*(C`\-\*(C'\fR, then \fBllvm-link\fR will
write its output to standard output.
.IP "\fB\-d\fR" 4
.IX Item "-d"
If specified, \fBllvm-link\fR prints a human-readable version of the output
bytecode file to standard error.
.IP "\fB\-\-help\fR" 4
.IX Item "--help"
Print a summary of command line options.
.IP "\fB\-v\fR" 4
.IX Item "-v"
Verbose mode. Print information about what \fBllvm-link\fR is doing. This
typically includes a message for each bytecode file linked in and for each
library found.

.IX Title "LLVM-NM 1"
.TH LLVM-NM 1 "2006-11-20" "CVS" "LLVM Command Guide"
.SH "NAME"
llvm\-nm \- list LLVM bytecode file's symbol table
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBllvm-nm\fR [\fIoptions\fR] [\fIfilenames...\fR]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBllvm-nm\fR utility lists the names of symbols from the \s-1LLVM\s0 bytecode files,
or \fBar\fR archives containing \s-1LLVM\s0 bytecode files, named on the command line.
Each symbol is listed along with some simple information about its provenance.
If no filename is specified, or \fI\-\fR is used as a filename, \fBllvm-nm\fR will
process a bytecode file on its standard input stream.
.PP
\&\fBllvm-nm\fR's default output format is the traditional \s-1BSD\s0 \fBnm\fR output format.
Each such output record consists of an (optional) 8\-digit hexadecimal address,
followed by a type code character, followed by a name, for each symbol. One
record is printed per line; fields are separated by spaces. When the address is
omitted, it is replaced by 8 spaces.
.PP
Type code characters currently supported, and their meanings, are as follows:
.IP "U" 4
.IX Item "U"
Named object is referenced but undefined in this bytecode file
.IP "C" 4
.IX Item "C"
Common (multiple defs link together into one def)
.IP "W" 4
.IX Item "W"
Weak reference (multiple defs link together into zero or one defs)
.IP "t" 4
.IX Item "t"
Local function (text) object
.IP "T" 4
.IX Item "T"
Global function (text) object
.IP "d" 4
.IX Item "d"
Local data object
.IP "D" 4
.IX Item "D"
Global data object
.IP "?" 4
Something unrecognizable
.PP
Because \s-1LLVM\s0 bytecode files typically contain objects that are not considered to
have addresses until they are linked into an executable image or dynamically
compiled \*(L"just\-in\-time\*(R", \fBllvm-nm\fR does not print an address for any symbol,
even symbols which are defined in the bytecode file.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-P\fR" 4
.IX Item "-P"
Use \s-1POSIX\s0.2 output format. Alias for \fB\-\-format=posix\fR.
.IP "\fB\-B\fR (default)" 4
.IX Item "-B (default)"
Use \s-1BSD\s0 output format. Alias for \fB\-\-format=bsd\fR.
.IP "\fB\-\-help\fR" 4
.IX Item "--help"
Print a summary of command-line options and their meanings.
.IP "\fB\-\-defined\-only\fR" 4
.IX Item "--defined-only"
Print only symbols defined in this bytecode file (as opposed to
symbols which may be referenced by objects in this file, but not
defined in this file.)
.IP "\fB\-\-extern\-only\fR, \fB\-g\fR" 4
.IX Item "--extern-only, -g"
Print only symbols whose definitions are external; that is, accessible
from other bytecode files.
.IP "\fB\-\-undefined\-only\fR, \fB\-u\fR" 4
.IX Item "--undefined-only, -u"
Print only symbols referenced but not defined in this bytecode file.
.IP "\fB\-\-format=\fR\fIfmt\fR, \fB\-f\fR" 4
.IX Item "--format=fmt, -f"
Select an output format; \fIfmt\fR may be \fIsysv\fR, \fIposix\fR, or \fIbsd\fR. The
default is \fIbsd\fR.
.SH "BUGS"
.IX Header "BUGS"
\&\fBllvm-nm\fR cannot demangle \*(C+ mangled names, like \s-1GNU\s0 \fBnm\fR can.
.SH "EXIT STATUS"
.IX Header "EXIT STATUS"
\&\fBllvm-nm\fR exits with an exit code of zero.

.IX Title "LLVM-PROF 1"
.TH LLVM-PROF 1 "2006-03-13" "CVS" "LLVM Command Guide"
.SH "NAME"
llvm\-prof \- print execution profile of LLVM program
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBllvm-prof\fR [\fIoptions\fR] [\fIbytecode file\fR] [\fIllvmprof.out\fR]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBllvm-prof\fR tool reads in an \fIllvmprof.out\fR file (which can
optionally use a specific file with the third program argument), a bytecode file
for the program, and produces a human readable report, suitable for determining
where the program hotspots are.
.PP
This program is often used in conjunction with the \fIutils/profile.pl\fR
script. This script automatically instruments a program, runs it with the \s-1JIT\s0,
then runs \fBllvm-prof\fR to format a report. To get more information about
\&\fIutils/profile.pl\fR, execute it with the \fB\-\-help\fR option.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-\-annotated\-llvm\fR or \fB\-A\fR" 4
.IX Item "--annotated-llvm or -A"
In addition to the normal report printed, print out the code for the
program, annotated with execution frequency information. This can be
particularly useful when trying to visualize how frequently basic blocks
are executed. This is most useful with basic block profiling
information or better.
.IP "\fB\-\-print\-all\-code\fR" 4
.IX Item "--print-all-code"
Using this option enables the \fB\-\-annotated\-llvm\fR option, but it
prints the entire module, instead of just the most commonly executed
functions.
.IP "\fB\-\-time\-passes\fR" 4
.IX Item "--time-passes"
Record the amount of time needed for each pass and print it to standard
error.
.SH "EXIT STATUS"
.IX Header "EXIT STATUS"
\&\fBllvm-prof\fR returns 1 if it cannot load the bytecode file or the profile
information. Otherwise, it exits with zero.
.SH "AUTHOR"
.IX Header "AUTHOR"
\&\fBllvm-prof\fR is maintained by the \s-1LLVM\s0 Team (<http://llvm.org>).

\&\fBllvm-ranlib\fR [\-\-version] [\-\-help] <archive\-file>
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBllvm-ranlib\fR command is similar to the common Unix utility, \f(CW\*(C`ranlib\*(C'\fR. It
adds or updates the symbol table in an \s-1LLVM\s0 archive file. Note that using the
\&\fBllvm-ar\fR modifier \fIs\fR is usually more efficient than running \fBllvm-ranlib\fR
which is only provided only for completness and compatibility. Unlike other
implementations of \f(CW\*(C`ranlib\*(C'\fR, \fBllvm-ranlib\fR indexes \s-1LLVM\s0 bytecode files, not
native object modules. You can list the contents of the symbol table with the
\&\f(CW\*(C`llvm\-nm \-s\*(C'\fR command.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fIarchive-file\fR" 4
.IX Item "archive-file"

.IX Item "--version"
Print the version of \fBllvm-ranlib\fR and exit without building a symbol table.
.IP "\fI\-\-help\fR" 4
.IX Item "--help"
Print usage help for \fBllvm-ranlib\fR and exit without building a symbol table.
.SH "EXIT STATUS"

If \fBllvm-ranlib\fR succeeds, it will exit with 0. If an error occurs, a non-zero
exit code will be returned.

.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBllvm-upgrade\fR [\fIoptions\fR] [\fIfilename\fR]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBllvm-upgrade\fR is the \s-1LLVM\s0 assembly upgrader. It reads a file containing
human-readable \s-1LLVM\s0 assembly language, and upgrades that assembly to the current
version of \s-1LLVM\s0. If the input is in the form currently accepted by \s-1LLVM\s0, then
no upgrades are performed.
.PP
The expected usage of this tool is as a filter, like this:
.Sp
.RS 4
\&\fBllvm\-1.9/bin/llvm\-dis < 1.9.bc | llvm-upgrade | llvm\-2.0/bin/llvm\-as \-o 2.0.bc\fR
.RE
.PP
If \fIfilename\fR is omitted or is \f(CW\*(C`\-\*(C'\fR, then \fBllvm-upgrade\fR reads its input from
standard input.
.PP
If an output file is not specified with the \fB\-o\fR option, then
\&\fBllvm-upgrade\fR sends its output to standard output.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-f\fR" 4
.IX Item "-f"
Force overwrite. Normally, \fBllvm-upgrade\fR will refuse to overwrite an
output file that already exists. With this option, \fBllvm-upgrade\fR
will overwrite the output file.
.IP "\fB\-\-help\fR" 4
.IX Item "--help"
Print a summary of command line options.
.IP "\fB\-o\fR \fIfilename\fR" 4
.IX Item "-o filename"
Specify the output file name. If \fIfilename\fR is \f(CW\*(C`\-\*(C'\fR, then \fBllvm-upgrade\fR
sends its output to standard output.
.SH "EXIT STATUS"
.IX Header "EXIT STATUS"
If \fBllvm-upgrade\fR succeeds, it will exit with 0. Otherwise, if an error
occurs, it will exit with a non-zero value.

.IX Title "LLVM2CPP 1"
.TH LLVM2CPP 1 "2006-08-10" "CVS" "LLVM Command Guide"
.SH "NAME"
llvm2xpp \- LLVM bytecode to LLVM C++ IR translator
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBllvm2cpp\fR [\fIoptions\fR] [\fIfilename\fR]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBllvm2cpp\fR translates from \s-1LLVM\s0 bytecode (.bc files) to a
corresponding \*(C+ source file that will make calls against the \s-1LLVM\s0 \*(C+ \s-1API\s0 to
build the same module as the input. By default, the \*(C+ output is a complete
program that builds the module, verifies it and then emits the module as
\&\s-1LLVM\s0 assembly. This technique assists with testing because the input to
\&\fBllvm2cpp\fR and the output of the generated \*(C+ program should be identical.
.PP
If \fIfilename\fR is omitted or is \f(CW\*(C`\-\*(C'\fR, then \fBllvm2cpp\fR reads its input from
standard input.
.PP
If an output file is not specified with the \fB\-o\fR option, then
\&\fBllvm2cpp\fR sends its output to a file or standard output by following
these rules:
.IP "\(bu" 4
If the input is standard input, then the output is standard output.
.IP "\(bu" 4
If the input is a file that ends with \f(CW\*(C`.bc\*(C'\fR, then the output file is of
the same name, except that the suffix is changed to \f(CW\*(C`.cpp\*(C'\fR.
.IP "\(bu" 4
If the input is a file that does not end with the \f(CW\*(C`.bc\*(C'\fR suffix, then the
output file has the same name as the input file, except that the \f(CW\*(C`.cpp\*(C'\fR
suffix is appended.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-f\fR" 4
.IX Item "-f"
Force overwrite. Normally, \fBllvm2cpp\fR will refuse to overwrite an
output file that already exists. With this option, \fBllvm2cpp\fR
will overwrite the output file and replace it with new \*(C+ source code.
.IP "\fB\-\-help\fR" 4
.IX Item "--help"
Print a summary of command line options.
.IP "\fB\-f\fR" 4
.IX Item "-f"
Normally, \fBllvm2cpp\fR will not overwrite an existing output file. With this
option, that default behavior is changed and the program will overwrite existing
output files.
.IP "\fB\-o\fR \fIfilename\fR" 4
.IX Item "-o filename"
Specify the output file name. If \fIfilename\fR is \f(CW\*(C`\-\*(C'\fR, then \fBllvm2cpp\fR
sends its output to standard output.
.IP "\fB\-funcname\fR \fIfunctionName\fR" 4
.IX Item "-funcname functionName"
Specify the name of the function to be generated. The generated code contains a
single function that produces the input module. By default its name is
\&\fImakeLLVMModule\fR. The \fB\-funcname\fR option overrides this default and allows
you to control the name of the generated function. This is handy in conjunction
with the \fB\-fragment\fR option when you only want \fBllvm2cpp\fR to generate a
single function that produces the module. With both options, such generated code
could be \fI#included\fR into another program.
.IP "\fB\-for\fR" 4
.IX Item "-for"
Specify the name of the thing for which \*(C+ code should be generated. By default
the entire input module is re\-generated. However, use of the various \fB\-gen\-*\fR
options can restrict what is produced. This option indicates what that
restriction is.
.IP "\fB\-gen\-program\fR" 4
.IX Item "-gen-program"
Specify that the output should be a complete program. Such program will recreate
\&\fBllvm2cpp\fR's input as an \s-1LLVM\s0 module, verify that module, and then write out
the module in \s-1LLVM\s0 assembly format. This is useful for doing identity tests
where the output of the generated program is identical to the input to
\&\fBllvm2cpp\fR. The \s-1LLVM\s0 DejaGnu test suite can make use of this fact. This is the
default form of generated output.
.Sp
If the \fB\-for\fR option is given with this option, it specifies the module
identifier to use for the module created.
.IP "\fB\-gen\-module\fR" 4
.IX Item "-gen-module"
Specify that the output should be a function that regenerates the module. It is
assumed that this output will be #included into another program that has already
arranged for the correct header files to be #included. The function generated
takes no arguments and returns a \fIModule*\fR.
.Sp
If the \fB\-for\fR option is given with this option, it specifies the module
identifier to use in creating the module returned by the generated function.
.IP "\fB\-gen\-contents\fR" 4
.IX Item "-gen-contents"
Specify that the output should be a function that adds the contents of the input
module to another module. It is assumed that the output will be #included into
another program that has already arranged for the correct header files to be
#included. The function generated takes a single argument of type \fIModule*\fR and
returns that argument. Note that Module level attributes such as endianess,
pointer size, target triple and inline asm are not passed on from the input
module to the destination module. Only the sub-elements of the module (types,
constants, functions, global variables) will be added to the input module.
.Sp
If the \fB\-for\fR option is given with this option, it specifies the module
identifier to set in the input module by the generated function.
.IP "\fB\-gen\-function\fR" 4
.IX Item "-gen-function"
Specify that the output should be a function that produces the definitions
necessary for a specific function to be added to a module. It is assumed that
the output will be #included into another program that has already arranged
for the correct header files to be #included. The function generated takes a
single argument of type \fIModule*\fR and returns the \fIFunction*\fR that it added to
the module. Note that only those things (types, constants, etc.) directly
needed in the definition of the function will be placed in the generated
function.
.Sp
The \fB\-for\fR option must be given with this option or an error will be produced.
The value of the option must be the name of a function in the input module for
which code should be generated. If the named function does not exist an error
will be produced.
.IP "\fB\-gen\-inline\fR" 4
.IX Item "-gen-inline"
This option is very analagous to \fB\-gen\-function\fR except that the generated
function will not re-produce the target function's definition. Instead, the body
of the target function is inserted into some other function passed as an
argument to the generated function. Similarly any arguments to the function must
be passed to the generated function. The result of the generated function is the
first basic block of the target function.
.Sp
The \fB\-for\fR option works the same way as it does for \fB\-gen\-function\fR.
.IP "\fB\-gen\-variable\fR" 4
.IX Item "-gen-variable"
Specify that the output should be a function that produces the definitions
necessary for a specific global variable to be added to a module. It is assumed
that the output will be #included into another program that has already arranged
for the correct header files to be #included. The function generated takes a
single argument of type \fIModule*\fR and returns the \fIGlobalVariable*\fR that it
added to the module. Note that only those things (types, constants, etc.)
directly needed in the definition of the global variable will be placed in the
generated function.
.Sp
The \fB\-for\fR option must be given with this option or an error will be produced.
THe value of the option must be the name of a global variable in the input
module for which code should be generated. If the named global variable does not
exist an error will be produced.
.IP "\fB\-gen\-type\fR" 4
.IX Item "-gen-type"
Specify that the output should be a function that produces the definitions
necessary for specific type to be added to a module. It is assumed that the
otuput will be #included into another program that has already arranged for the
correct header files to be #included. The function generated take a single
argument of type \fIModule*\fR and returns the \fIType*\fR that it added to the
module. Note that the generated function will only add the necessary type
definitions to (possibly recursively) define the requested type.
.Sp
The \fB\-for\fR option must be given with this option or an error will be produced.
The value of the option must be the name of a global type in the input module
for which code should be generated. If the named type does not exist an error
will be produced.
.IP "\fB\-stats\fR" 4
.IX Item "-stats"
Show pass statistics (not interesting in this program).
.IP "\fB\-time\-passes\fR" 4
.IX Item "-time-passes"
Show pass timing statistics (not interesting in this program).
.IP "\fB\-version\fR" 4
.IX Item "-version"
Show the version number of this program.

.TH LLVMC 1 "2007-02-11" "CVS" "LLVM Command Guide"
.SH "NAME"
llvmc \- The LLVM Compiler Driver (experimental)
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBllvmc\fR [\fIoptions\fR] [\fIfilenames\fR...]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBllvmc\fR is a configurable driver for invoking other \s-1LLVM\s0 (and non\-LLVM) tools
in order to compile, optimize and link software for multiple languages. For
those familiar with \s-1FSF\s0's \fBgcc\fR tool, it is very similar. Please note that
\&\fBllvmc\fR is considered an experimental tool. \fBllvmc\fR has the following goals:
.IP "* provide a single point of access to the \s-1LLVM\s0 tool set," 4
.IX Item "provide a single point of access to the LLVM tool set,"
.PD 0
.IP "* hide the complexities of the \s-1LLVM\s0 tools through a single interface," 4
.IX Item "hide the complexities of the LLVM tools through a single interface,"
.IP "* make integration of existing non-LLVM tools simple," 4
.IX Item "make integration of existing non-LLVM tools simple,"
.IP "* extend the capabilities of minimal front ends, and" 4
.IX Item "extend the capabilities of minimal front ends, and"
.IP "* make the interface for compiling consistent for all languages." 4
.IX Item "make the interface for compiling consistent for all languages."
.PD
.PP
The tool itself does nothing with a user's program. It merely invokes other
tools to get the compilation tasks done.
.PP
The options supported by \fBllvmc\fR generalize the compilation process and
provide a consistent and simple interface for multiple programming languages.
This makes it easier for developers to get their software compiled with \s-1LLVM\s0.
Without \fBllvmc\fR, developers would need to understand how to invoke the
front-end compiler, optimizer, assembler, and linker in order to compile their
programs. \fBllvmc\fR's sole mission is to trivialize that process.
.Sh "Basic Operation"
.IX Subsection "Basic Operation"
\&\fBllvmc\fR always takes the following basic actions:
.IP "* Command line options and filenames are collected." 4
.IX Item "Command line options and filenames are collected."
The command line options provide the marching orders to \fBllvmc\fR on what actions
it should perform. This is the \fIrequest\fR the user is making of \fBllvmc\fR and it
is interpreted first.
.IP "* Configuration files are read." 4
.IX Item "Configuration files are read."
Based on the options and the suffixes of the filenames presented, a set of
configuration files are read to configure the actions \fBllvmc\fR will take.
Configuration files are provided by either \s-1LLVM\s0 or the front end compiler tools
that \fBllvmc\fR invokes. Users generally don't need to be concerned with the
contents of the configuration files.
.IP "* Determine actions to take." 4
.IX Item "Determine actions to take."
The tool chain needed to complete the task is determined. This is the primary
work of \fBllvmc\fR. It breaks the request specified by the command line options
into a set of basic actions to be done:
.RS 4
.IP "* Pre\-processing: gathering/filtering compiler input (optional)." 4
.IX Item "Pre-processing: gathering/filtering compiler input (optional)."
.PD 0
.IP "* Translation: source language to bytecode conversion." 4
.IX Item "Translation: source language to bytecode conversion."
.IP "* Assembly: bytecode to native code conversion." 4
.IX Item "Assembly: bytecode to native code conversion."
.IP "* Optimization: conversion of bytecode to something that runs faster." 4
.IX Item "Optimization: conversion of bytecode to something that runs faster."
.IP "* Linking: combining multiple bytecodes to produce executable program." 4
.IX Item "Linking: combining multiple bytecodes to produce executable program."
.RE
.RS 4
.RE
.IP "* Execute actions." 4
.IX Item "Execute actions."
.PD
The actions determined previously are executed sequentially and then
\&\fBllvmc\fR terminates.
.SH "OPTIONS"
.IX Header "OPTIONS"
.Sh "Control Options"
.IX Subsection "Control Options"
Control options tell \fBllvmc\fR what to do at a high level. The
following control options are defined:
.IP "\fB\-c\fR or \fB\-\-compile\fR" 4
.IX Item "-c or --compile"
This option specifies that the linking phase is not to be run. All
previous phases, if applicable will run. This is generally how a given
bytecode file is compiled and optimized for a source language module.
.IP "\fB\-k\fR or \fB\-\-link\fR or default" 4
.IX Item "-k or --link or default"
This option (or the lack of any control option) specifies that all stages
of compilation, optimization, and linking should be attempted. Source files
specified on the command line will be compiled and linked with objects and
libraries also specified.
.IP "\fB\-S\fR" 4
.IX Item "-S"
This option specifies that compilation should end in the creation of
an \s-1LLVM\s0 assembly file that can be later converted to an \s-1LLVM\s0 object
file.
.IP "\fB\-E\fR" 4
.IX Item "-E"
This option specifies that no compilation or linking should be
performed. Only pre\-processing, if applicable to the language being
compiled, is performed. For languages that support it, this will
result in the output containing the raw input to the compiler.
.Sh "Optimization Options"
.IX Subsection "Optimization Options"
Optimization with \fBllvmc\fR is based on goals and specified with
the following \-O options. The specific details of which
optimizations run is controlled by the configuration files because
each source language will have different needs.
.IP "\fB\-O1\fR or \fB\-O0\fR (default, fast compilation)" 4
.IX Item "-O1 or -O0 (default, fast compilation)"
Only those optimizations that will hasten the compilation (mostly by reducing
the output) are applied. In general these are extremely fast and simple
optimizations that reduce emitted code size. The goal here is not to make the
resulting program fast but to make the compilation fast. If not specified,
this is the default level of optimization.
.IP "\fB\-O2\fR (basic optimization)" 4
.IX Item "-O2 (basic optimization)"
This level of optimization specifies a balance between generating good code
that will execute reasonably quickly and not spending too much time optimizing
the code to get there. For example, this level of optimization may include
things like global common subexpression elimination, aggressive dead code
elimination, and scalar replication.
.IP "\fB\-O3\fR (aggressive optimization)" 4
.IX Item "-O3 (aggressive optimization)"
This level of optimization aggressively optimizes each set of files compiled
together. However, no link-time inter-procedural optimization is performed.
This level implies all the optimizations of the \fB\-O1\fR and \fB\-O2\fR optimization
levels, and should also provide loop optimizations and compile time
inter-procedural optimizations. Essentially, this level tries to do as much
as it can with the input it is given but doesn't do any link time \s-1IPO\s0.
.IP "\fB\-O4\fR (link time optimization)" 4
.IX Item "-O4 (link time optimization)"
In addition to the previous three levels of optimization, this level of
optimization aggressively optimizes each program at link time. It employs
basic analysis and basic link-time inter-procedural optimizations,
considering the program as a whole.
.IP "\fB\-O5\fR (aggressive link time optimization)" 4
.IX Item "-O5 (aggressive link time optimization)"
This is the same as \fB\-O4\fR except it employs aggressive analyses and
aggressive inter-procedural optimization.
.IP "\fB\-O6\fR (profile guided optimization: not implemented)" 4
.IX Item "-O6 (profile guided optimization: not implemented)"
This is the same as \fB\-O5\fR except that it employs profile-guided
re-optimization of the program after it has executed. Note that this implies
a single level of re-optimization based on runtime profile analysis. Once
the re-optimization has completed, the profiling instrumentation is
removed and final optimizations are employed.
.IP "\fB\-O7\fR (lifelong optimization: not implemented)" 4
.IX Item "-O7 (lifelong optimization: not implemented)"
This is the same as \fB\-O5\fR and similar to \fB\-O6\fR except that re-optimization
is performed through the life of the program. That is, each run will update
the profile by which future re-optimizations are directed.
.Sh "Input Options"
.IX Subsection "Input Options"
.IP "\fB\-l\fR \fI\s-1LIBRARY\s0\fR" 4
.IX Item "-l LIBRARY"
This option instructs \fBllvmc\fR to locate a library named \fI\s-1LIBRARY\s0\fR and search
it for unresolved symbols when linking the program.
.IP "\fB\-L\fR \fIpath\fR" 4
.IX Item "-L path"
This option instructs \fBllvmc\fR to add \fIpath\fR to the list of places in which
the linker will
.IP "\fB\-x\fR \fI\s-1LANGUAGE\s0\fR" 4
.IX Item "-x LANGUAGE"
This option instructs \fBllvmc\fR to regard the following input files as
containing programs in the language \fI\s-1LANGUAGE\s0\fR. Normally, input file languages
are identified by their suffix but this option will override that default
behavior. The \fB\-x\fR option stays in effect until the end of the options or
a new \fB\-x\fR option is encountered.
.Sh "Output Options"
.IX Subsection "Output Options"
.IP "\fB\-m\fR\fIarch\fR" 4
.IX Item "-march"
This option selects the back end code generator to use. The \fIarch\fR portion
of the option names the back end to use.
.IP "\fB\-\-native\fR" 4
.IX Item "--native"
Normally, \fBllvmc\fR produces bytecode files at most stages of compilation.
With this option, \fBllvmc\fR will arrange for native object files to be
generated with the \fB\-c\fR option, native assembly files to be generated
with the \fB\-S\fR option, and native executables to be generated with the
\&\fB\-\-link\fR option. In the case of the \fB\-E\fR option, the output will not
differ as there is no \fInative\fR version of pre-processed output.
.IP "\fB\-o\fR \fIfilename\fR" 4
.IX Item "-o filename"
Specify the output file name. The contents of the file depend on other
options.
.Sh "Information Options"
.IX Subsection "Information Options"
.IP "\fB\-n\fR or \fB\-\-no\-op\fR" 4
.IX Item "-n or --no-op"
This option tells \fBllvmc\fR to do everything but actually execute the
resulting tools. In combination with the \fB\-v\fR option, this causes \fBllvmc\fR
to merely print out what it would have done.
.IP "\fB\-v\fR or \fB\-\-verbose\fR" 4
.IX Item "-v or --verbose"
This option will cause \fBllvmc\fR to print out (on standard output) each of the
actions it takes to accomplish the objective. The output will immediately
precede the invocation of other tools.
.IP "\fB\-\-stats\fR" 4
.IX Item "--stats"
Print all statistics gathered during the compilation to the standard error.
Note that this option is merely passed through to the sub-tools to do with
as they please.
.IP "\fB\-\-time\-passes\fR" 4
.IX Item "--time-passes"
Record the amount of time needed for each optimization pass and print it
to standard error. Like \fB\-\-stats\fR this option is just passed through to
the sub-tools to do with as they please.
.IP "\fB\-\-time\-programs\fR" 4
.IX Item "--time-programs"
Record the amount of time each program (compilation tool) takes and print
it to the standard error.
.Sh "Language Specific Options"
.IX Subsection "Language Specific Options"
.IP "\fB\-T,pre\fR=\fIoptions\fR" 4
.IX Item "-T,pre=options"
Pass an arbitrary option to the pre\-processor.
.IP "\fB\-T,opt\fR=\fIoptions\fR" 4
.IX Item "-T,opt=options"
Pass an arbitrary option to the optimizer.
.IP "\fB\-T,lnk\fR=\fIoptions\fR" 4
.IX Item "-T,lnk=options"
Pass an arbitrary option to the linker.
.IP "\fB\-T,asm\fR=\fIoptions\fR" 4
.IX Item "-T,asm=options"
Pass an arbitrary option to the code generator.
.Sh "C/\*(C+ Specific Options"
.IX Subsection "C/ Specific Options"
.IP "\fB\-I\fR\fIpath\fR" 4
.IX Item "-Ipath"
This option is just passed through to a C or \*(C+ front end compiler to tell it
where include files can be found.
.IP "\fB\-D\fR\fIsymbol\fR" 4
.IX Item "-Dsymbol"
This option is just passed through to a C or \*(C+ front end compiler to tell it
to define a symbol.
.Sh "Miscellaneous Options"
.IX Subsection "Miscellaneous Options"
.IP "\fB\-\-help\fR" 4
.IX Item "--help"
Print a summary of command line options.
.IP "\fB\-\-version\fR" 4
.IX Item "--version"
This option will cause \fBllvmc\fR to print out its version number and terminate.
.Sh "Advanced Options"
.IX Subsection "Advanced Options"
You better know what you're doing if you use these options. Improper use
of these options can produce drastically wrong results.
.IP "\fB\-\-config\-dir\fR \fIdirname\fR" 4
.IX Item "--config-dir dirname"
This option tells \fBllvmc\fR to read configuration data from the \fIdirectory\fR
named \fIdirname\fR. Data from such directories will be read in the order
specified on the command line after all other standard configuration files have
been read. This allows users or groups of users to conveniently create
their own configuration directories in addition to the standard ones to which
they may not have write access.
.Sh "Unimplemented Options"
.IX Subsection "Unimplemented Options"
The options below are not currently implemented in \fBllvmc\fR but will be
eventually. They are documented here as \*(L"future design\*(R".
.IP "\fB\-\-show\-config\fR \fI[suffixes...]\fR" 4
.IX Item "--show-config [suffixes...]"
When this option is given, the only action taken by \fBllvmc\fR is to show its
final configuration state in the form of a configuration file. No compilation
tasks will be conducted when this option is given; processing will stop once
the configuration has been printed. The optional (comma separated) list of
suffixes controls what is printed. Without any suffixes, the configuration
for all languages is printed. With suffixes, only the languages pertaining
to those file suffixes will be printed. The configuration information is
printed after all command line options and configuration files have been
read and processed. This allows the user to verify that the correct
configuration data has been read by \fBllvmc\fR.
.IP "\fB\-\-config\fR :\fIsection\fR:\fIname\fR=\fIvalue\fR" 4
.IX Item "--config :section:name=value"
This option instructs \fBllvmc\fR to accept \fIvalue\fR as the value for configuration
item \fIname\fR in the section named \fIsection\fR. This is a quick way to override
a configuration item on the command line without resorting to changing the
configuration files.
.IP "\fB\-\-config\-only\-from\fR \fIdirname\fR" 4
.IX Item "--config-only-from dirname"
This option tells \fBllvmc\fR to skip the normal processing of configuration
files and only configure from the contents of the \fIdirname\fR directory. Multiple
\&\fB\-\-config\-only\-from\fR options may be given in which case the directories are
read in the order given on the command line.
.IP "\fB\-\-emit\-raw\-code\fR" 4
.IX Item "--emit-raw-code"
No optimization is done whatsoever. The compilers invoked by \fBllvmc\fR with
this option given will be instructed to produce raw, unoptimized code. This
option is useful only to front end language developers and therefore does not
participate in the list of \fB\-O\fR options. This is distinctly different from
the \fB\-O0\fR option (a synonym for \fB\-O1\fR) because those optimizations will
reduce code size to make compilation faster. With \fB\-\-emit\-raw\-code\fR, only
the full raw code produced by the compiler will be generated.
.SH "EXIT STATUS"
.IX Header "EXIT STATUS"
If \fBllvmc\fR succeeds, it will exit with 0. Otherwise, if an error
occurs, it will exit with a non-zero value and no compilation actions
will be taken. If one of the compilation tools returns a non-zero
status, pending actions will be discarded and \fBllvmc\fR will return the
same result code as the failing compilation tool.
.SH "DEFICIENCIES"
.IX Header "DEFICIENCIES"
\&\fBllvmc\fR is considered an experimental \s-1LLVM\s0 tool because it has these
deficiencies:
.IP "Insufficient support for native linking" 4
.IX Item "Insufficient support for native linking"
Because \fBllvm-ld\fR doesn't handle native linking, neither can \fBllvmc\fR
.IP "Poor configuration support" 4
.IX Item "Poor configuration support"
The support for configuring new languages, etc. is weak. There are many
command line configurations that cannot be achieved with the current
support. Furthermore the grammar is cumbersome for configuration files.
Please see <http://llvm.org/PR686> for further details.
.IP "Does not handle target specific configurations" 4
.IX Item "Does not handle target specific configurations"
This is one of the major deficiencies, also addressed in

.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBllvm-gcc\fR command is the \s-1LLVM\s0 C front end. It is a modified
version of gcc that compiles C/ObjC programs into native objects, \s-1LLVM\s0
bytecode or \s-1LLVM\s0 assembly language, depending upon the options.
.PP
By default, \fBllvm-gcc\fR compiles to native objects just like \s-1GCC\s0 does. If the
\&\fB\-emit\-llvm\fR option is given then it will generate \s-1LLVM\s0 bytecode files instead.
If \fB\-S\fR (assembly) is also given, then it will generate \s-1LLVM\s0 assembly.
.PP
Being derived from the \s-1GNU\s0 Compiler Collection, \fBllvm-gcc\fR has many
of gcc's features and accepts most of gcc's options. It handles a
number of gcc's extensions to the C programming language.
.SH "OPTIONS"

Do not generate an \s-1LLVM\s0 bytecode file. Rather, compile the source
file into an \s-1LLVM\s0 assembly language file.
.IP "\fB\-c\fR" 4
.IX Item "-c"
Do not generate a linked executable. Rather, compile the source
file into an \s-1LLVM\s0 bytecode file. This bytecode file can then be
linked with other bytecode files later on to generate a full \s-1LLVM\s0
executable.
.IP "\fB\-o\fR \fIfilename\fR" 4
.IX Item "-o filename"
Specify the output file to be \fIfilename\fR.
.IP "\fB\-I\fR \fIdirectory\fR" 4

.IX Title "OPT 1"
.TH OPT 1 "2007-02-02" "CVS" "LLVM Command Guide"
.SH "NAME"
opt \- LLVM optimizer
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBopt\fR [\fIoptions\fR] [\fIfilename\fR]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBopt\fR command is the modular \s-1LLVM\s0 optimizer and analyzer. It takes \s-1LLVM\s0
bytecode as input, runs the specified optimizations or analyses on it, and then
outputs the optimized \s-1LLVM\s0 bytecode or the analysis results. The function of
\&\fBopt\fR depends on whether the \fB\-analyze\fR option is given.
.PP
When \fB\-analyze\fR is specified, \fBopt\fR performs various analyses of \s-1LLVM\s0
bytecode. It will usually print the results on standard output, but in a few
cases, it will print output to standard error or generate a file with the
analysis output, which is usually done when the output is meant for another
program.
.PP
While \fB\-analyze\fR is \fInot\fR given, \fBopt\fR attempts to produce an optimized
bytecode file. The optimizations available via \fBopt\fR depend upon what
libraries were linked into it as well as any additional libraries that have
been loaded with the \fB\-load\fR option. Use the \fB\-help\fR option to determine
what optimizations you can use.
.PP
If \fIfilename\fR is omitted from the command line or is \fI\-\fR, \fBopt\fR reads its
input from standard input. The input must be an \s-1LLVM\s0 bytecode file.
.PP
If an output filename is not specified with the \fB\-o\fR option, \fBopt\fR
writes its output to the standard output.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-f\fR" 4
.IX Item "-f"
Force overwrite. Normally, \fBopt\fR will refuse to overwrite an
output file that already exists. With this option, \fBopt\fR will
overwrite the output file and replace it with new bytecode.
.IP "\fB\-help\fR" 4
.IX Item "-help"
Print a summary of command line options.
.IP "\fB\-o\fR \fIfilename\fR" 4
.IX Item "-o filename"
Specify the output filename.
.IP "\fB\-{passname}\fR" 4
.IX Item "-{passname}"
\&\fBopt\fR provides the ability to run any of \s-1LLVM\s0's optimization or analysis passes
in any order. The \fB\-help\fR option lists all the passes available. The order in
which the options occur on the command line are the order in which they are
executed (within pass constraints).
.IP "\fB\-std\-compile\-opts\fR" 4
.IX Item "-std-compile-opts"
This is short hand for a standard list of \fIcompile time optimization\fR passes.
This is typically used to optimize the output from the llvm-gcc front end. It
might be useful for other front end compilers as well. To discover the full set
of options available, use the following command:
.Sp
.Vb 1
\& llvm-as < /dev/null | opt -std-compile-opts -disable-output -debug-pass=Arguments
.Ve
.IP "\fB\-disable\-inlining\fR" 4
.IX Item "-disable-inlining"
This option is only meaningful when \fB\-std\-compile\-opts\fR is given. It simply
removes the inlining pass from the standard list.
.IP "\fB\-disable\-opt\fR" 4
.IX Item "-disable-opt"
This option is only meaningful when \fB\-std\-compile\-opts\fR is given. It disables
most, but not all, of the \fB\-std\-compile\-opts\fR. The ones that remain are
\&\fB\-verify\fR, \fB\-lower\-setjmp\fR, and \fB\-funcresolve\fR.
.IP "\fB\-strip\-debug\fR" 4
.IX Item "-strip-debug"
This option causes opt to strip debug information from the module before
applying other optimizations. It is essentially the same as \fB\-strip\fR but it
ensures that stripping of debug information is done first.
.IP "\fB\-verify\-each\fR" 4
.IX Item "-verify-each"
This option causes opt to add a verify pass after every pass otherwise specified
on the command line (including \fB\-verify\fR). This is useful for cases where it
is suspected that a pass is creating an invalid module but it is not clear which
pass is doing it. The combination of \fB\-std\-compile\-opts\fR and \fB\-verify\-each\fR
can quickly track down this kind of problem.
.IP "\fB\-profile\-info\-file\fR \fIfilename\fR" 4
.IX Item "-profile-info-file filename"
Specify the name of the file loaded by the \-profile\-loader option.
.IP "\fB\-stats\fR" 4
.IX Item "-stats"
Print statistics.
.IP "\fB\-time\-passes\fR" 4
.IX Item "-time-passes"
Record the amount of time needed for each pass and print it to standard
error.
.IP "\fB\-debug\fR" 4
.IX Item "-debug"
If this is a debug build, this option will enable debug printouts
from passes which use the \fI\s-1\fIDEBUG\s0()\fI\fR macro. See the \fB\s-1LLVM\s0 Programmer's
Manual\fR, section \fI#DEBUG\fR for more information.
.IP "\fB\-load\fR=\fIplugin\fR" 4
.IX Item "-load=plugin"
Load the dynamic object \fIplugin\fR. This object should register new optimization
or analysis passes. Once loaded, the object will add new command line options to
enable various optimizations or analyses. To see the new complete list of
optimizations, use the \fB\-help\fR and \fB\-load\fR options together. For example:
.Sp
.Vb 1
\& opt -load=plugin.so -help
.Ve
.IP "\fB\-p\fR" 4
.IX Item "-p"
Print module after each transformation.
.SH "EXIT STATUS"
.IX Header "EXIT STATUS"
If \fBopt\fR succeeds, it will exit with 0. Otherwise, if an error
occurs, it will exit with a non-zero value.
.SH "AUTHORS"
.IX Header "AUTHORS"

.IX Title "STKRC 1"
.TH STKRC 1 "2006-03-13" "CVS" "LLVM Command Guide"
.SH "NAME"
stkrc \- Stacker Compiler
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBstkrc\fR [\fIoptions\fR] [\fIfilename\fR]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBstkrc\fR command is the compiler for the Stacker language. Stacker is a
simple stack based, Forth-like language that was written as a demonstration
language for \s-1LLVM\s0. For details on the language, please see
<http://llvm.org/docs/Stacker.html> . The \fBstkrc\fR compiler is fairly
minimal. It compiles to bytecode only and doesn't perform any optimizations.
The output of stkrc (a bytecode file) can be piped through other \s-1LLVM\s0 tools
for optimization and linking.
.PP
If \fIfilename\fR is omitted or is \f(CW\*(C`\-\*(C'\fR, then \fBstkrc\fR reads its input
from standard input. This is useful for combining the tool into a pipeline.
.PP
If an output file is not specified with the \fB\-o\fR option, then
\&\fBllvm-as\fR sends its output to a file or standard output by following
these rules:
.IP "\(bu" 4
If the input is standard input, then the output is standard output.
.IP "\(bu" 4
If the input is a file that ends with \f(CW\*(C`.st\*(C'\fR, then the output file is of
the same name, except that the suffix is changed to \f(CW\*(C`.bc\*(C'\fR.
.IP "\(bu" 4
If the input is a file that does not end with the \f(CW\*(C`.st\*(C'\fR suffix, then the
output file has the same name as the input file, except that the \f(CW\*(C`.bc\*(C'\fR
suffix is appended.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-o\fR \fIfilename\fR" 4
.IX Item "-o filename"
Specify the output file name. If \fIfilename\fR is \f(CW\*(C`\-\*(C'\fR, then \fBllvm-as\fR
sends its output to standard output.
.IP "\fB\-stats\fR" 4
.IX Item "-stats"
Print statistics acquired during compilation.
.IP "\fB\-time\-passes\fR" 4
.IX Item "-time-passes"
Record the amount of time needed for each pass and print it to standard
error.
.IP "\fB\-f\fR" 4
.IX Item "-f"
Force the output to be written. Normally, \fBstkrc\fR won't overwrite an existing
bytecode file. This option overrides that behavior.
.IP "\fB\-s\fR \fIstacksize\fR" 4
.IX Item "-s stacksize"
Specify the stack size for the program. The default stack size, 1024, should be
sufficient for most programs. For very large programs, especially those that
recurse a lot, you might want to provide a larger value. Each unit of this
value consumes 8 bytes of memory.
.IP "\fB\-help\fR" 4
.IX Item "-help"
Print a summary of command line options.
.SH "EXIT STATUS"
.IX Header "EXIT STATUS"
If \fBstkrc\fR succeeds, it will exit with 0. Otherwise, if an error
occurs, it will exit with a non-zero value, usually 1.

release incorporates a large number of enhancements, new features, and bug Being the first major release since 1.0, this release is different in several
fixes. We recommend that all users of previous LLVM versions upgrade. ways from our previous releases:</p>
</p>
<ol>
<li>We took this as an opportunity to
break backwards compatibility with the LLVM 1.x bytecode and .ll file format.
If you have LLVM 1.9 .ll files that you would like to upgrade to LLVM 2.x, we
recommend the use of the stand alone <a href="#llvm-upgrade">llvm-upgrade</a>
tool (which is included with 2.0). We intend to keep compatibility with .ll
and .bc formats within the 2.x release series, like we did within the 1.x
series.</li>
<li>There are several significant change to the LLVM IR and internal APIs, such
as a major overhaul of the type system, the completely new bitcode file
format, etc (described below).</li>
<li>We designed the release around a 6 month release cycle instead of the usual
3-month cycle. This gave us extra time to develop and test some of the
more invasive features in this release.</li>
<li>LLVM 2.0 no longer supports the llvm-gcc3 front-end. Users are required to
upgrade to llvm-gcc4. llvm-gcc4 includes many features over
llvm-gcc3, is faster, and is <a href="CFEBuildInstrs.html">much easier to
build from source</a>.</li>
</ol>
<p>Note that while this is a major version bump, this release has been
extensively tested on a wide range of software. It is easy to say that this
is our best release yet, in terms of both features and correctness. This is
the first LLVM release to correctly compile and optimize major software like
LLVM itself, Mozilla/Seamonkey, Qt 4.3rc1, kOffice, etc out of the box on
linux/x86.

<div class="doc_text"> <div class="doc_text">
<p>LLVM 1.9 now fully supports the x86-64 instruction set on Mac OS/X, and
supports it on Linux (and other operating systems) when compiling in -static <p>Changes to the LLVM IR itself:</p>
mode. LLVM includes JIT support for X86-64, and supports both Intel EMT-64T
and AMD-64 architectures. The X86-64 instruction set permits addressing a <ul>
64-bit addressing space and provides the compiler with twice the
number of integer registers to use.</p> <li>Integer types are now completely signless. This means that we
have types like i8/i16/i32 instead of ubyte/sbyte/short/ushort/int
etc. LLVM operations that depend on sign have been split up into
separate instructions (<a href="http://llvm.org/PR950">PR950</a>). This
eliminates cast instructions that just change the sign of the operands (e.g.
int -> uint), which reduces the size of the IR and makes optimizers
simpler to write.</li>
<li>Integer types with arbitrary bitwidths (e.g. i13, i36, i42, i1057, etc) are
now supported in the LLVM IR and optimizations (<a
href="http://llvm.org/PR1043">PR1043</a>). However, neither llvm-gcc
(<a href="http://llvm.org/PR1284">PR1284</a>) nor the native code generators
(<a href="http://llvm.org/PR1270">PR1270</a>) support non-standard width
integers yet.</li>
<li>'Type planes' have been removed (<a href="http://llvm.org/PR411">PR411</a>).
It is no longer possible to have two values with the same name in the
same symbol table. This simplifies LLVM internals, allowing significant
speedups.</li>
<li>Global variables and functions in .ll files are now prefixed with
@ instead of % (<a href="http://llvm.org/PR645">PR645</a>).</li>
<li>The LLVM 1.x "bytecode" format has been replaced with a
completely new binary representation, named 'bitcode'. The <a
href="BitCodeFormat.html">Bitcode Format</a> brings a
number of advantages to the LLVM over the old bytecode format: it is denser
(files are smaller), more extensible, requires less memory to read,
is easier to keep backwards compatible (so LLVM 2.5 will read 2.0 .bc
files), and has many other nice features.</li>
<li>Load and store instructions now track the alignment of their pointer
(<a href="http://www.llvm.org/PR400">PR400</a>). This allows the IR to
express loads that are not sufficiently aligned (e.g. due to '<tt>#pragma
packed</tt>') or to capture extra alignment information.</li>
</ul>
<p>Major new features:</p>
<ul>
<li>A number of ELF features are now supported by LLVM, including 'visibility',
extern weak linkage, Thread Local Storage (TLS) with the <tt>__thread</tt>
keyword, and symbol aliases.
Among other things, this means that many of the special options needed to
configure llvm-gcc on linux are no longer needed, and special hacks to build
large C++ libraries like Qt are not needed.</li>
<li>LLVM now has a new MSIL backend. <tt>llc -march=msil</tt> will now turn LLVM
into MSIL (".net") bytecode. This is still fairly early development
with a number of limitations.</li>
<li>A new <a href="CommandGuide/html/llvm-upgrade.html">llvm-upgrade</a> tool
exists to migrates LLVM 1.9 .ll files to LLVM 2.0 syntax.</li>

<li>The 'analyze' tool has been merged into the 'opt' tool.</li>
<li><tt>Type::IntTy</tt>, <tt>Type::UIntTy</tt>, <tt>Type::SByteTy</tt>, ... are
replaced by <tt>Type::Int8Ty</tt>, <tt>Type::Int16Ty</tt>, etc. LLVM types
have always corresponded to fixed size types
(e.g. long was always 64-bits), but the type system no longer includes
information about the sign of the type. Also, the
<tt>Type::isPrimitiveType()</tt> method now returns false for integers.</li>
<li>Several classes (<tt>CallInst</tt>, <tt>GetElementPtrInst</tt>,
<tt>ConstantArray</tt>, etc), that once took <tt>std::vector</tt> as
arguments now take ranges instead. For example, you can create a
<tt>GetElementPtrInst</tt> with code like:
<pre>
Value *Ops[] = { Op1, Op2, Op3 };
GEP = new GetElementPtrInst(BasePtr, Ops, 3);
</pre>
This avoids creation of a temporary vector (and a call to malloc/free). If
you have an <tt>std::vector</tt>, use code like this:
<pre>
std::vector&lt;Value*&gt; Ops = ...;
GEP = new GetElementPtrInst(BasePtr, &amp;Ops[0], Ops.size());
</pre>
</li>
<li><tt>CastInst</tt> is now abstract and its functionality is split into
several parts, one for each of the <a href="LangRef.html#convertops">new
cast instructions</a>.</li>
<li><tt>Instruction::getNext()/getPrev()</tt> are now private (along with
<tt>BasicBlock::getNext</tt>, etc), for efficiency reasons (they are now no
longer just simple pointers). Please use <tt>BasicBlock::iterator</tt>, etc
instead.
</li>
<li><tt>Module::getNamedFunction()</tt> is now called
<tt>Module::getFunction()</tt>.</li>

This directory contains a sample language front end for LLVM.
It is a *very* simple/crude implementation of FORTH. It has many
deficiencies but provides enough basics to give you an idea of
what programming a new language front end for LLVM looks like.
To keep things simple, Stacker has the following limitations:
1. Only a single, global stack is manipulated.
2. There is no interpretation, everything is compiled.
3. There's no type/bounds checking .. you're on your own.
4. There's no floating point support.
5. Only stdin can be read. Only stdout can be written. No other
file I/O is supported.
As such, this isn't a very useful language for anything other than
the most trivial of programs. It is, however, a good learning tool
(for both the author and the student).
