[docs] Remove POD based man page docs (and build system support).
- Currently this leaves us with less build system support (e.g., installing man pages) for the docs than is desired. I'm working on fixing this, but it may take a while. If someone finds this particularly egregious let me know and I will prioritize it.

This behavior is particularly -useful for the testsuite, which wants to verify that the output of some tool -(e.g. llc) contains the expected information (for example, a movsd from esp or -whatever is interesting). This is similar to using grep, but it is optimized -for matching multiple different inputs in one file in a specific order. - -The I<match-filename> file specifies the file that contains the patterns to -match. The file to verify is always read from standard input. - -=head1 OPTIONS - -=over - -=item B<-help> - -Print a summary of command line options. - -=item B<--check-prefix> I<prefix> - -FileCheck searches the contents of I<match-filename> for patterns to match. By -default, these patterns are prefixed with "CHECK:". If you'd like to use a -different prefix (e.g. because the same input file is checking multiple -different tool or options), the B<--check-prefix> argument allows you to specify -a specific prefix to match. - -=item B<--strict-whitespace> - -By default, FileCheck canonicalizes input horizontal whitespace (spaces and -tabs) which causes it to ignore these differences (a space will match a tab). -The --strict-whitespace argument disables this behavior. - -=item B<-version> - -Show the version number of this program. - -=back - -=head1 EXIT STATUS - -If B<FileCheck> verifies that the file matches the expected contents, it exits -with 0. Otherwise, if not, or if an error occurs, it will exit with a non-zero -value. - -=head1 TUTORIAL - -FileCheck is typically used from LLVM regression tests, being invoked on the RUN -line of the test. A simple example of using FileCheck from a RUN line looks -like this: - - ; RUN: llvm-as < %s | llc -march=x86-64 | FileCheck %s - -This syntax says to pipe the current file ("%s") into llvm-as, pipe that into -llc, then pipe the output of llc into FileCheck. This means that FileCheck will -be verifying its standard input (the llc output) against the filename argument -specified (the original .ll file specified by "%s"). To see how this works, -let's look at the rest of the .ll file (after the RUN line): - - define void @sub1(i32* %p, i32 %v) { - entry: - ; CHECK: sub1: - ; CHECK: subl - %0 = tail call i32 @llvm.atomic.load.sub.i32.p0i32(i32* %p, i32 %v) - ret void - } - - define void @inc4(i64* %p) { - entry: - ; CHECK: inc4: - ; CHECK: incq - %0 = tail call i64 @llvm.atomic.load.add.i64.p0i64(i64* %p, i64 1) - ret void - } - -Here you can see some "CHECK:" lines specified in comments. Now you can see -how the file is piped into llvm-as, then llc, and the machine code output is -what we are verifying. FileCheck checks the machine code output to verify that -it matches what the "CHECK:" lines specify. - -The syntax of the CHECK: lines is very simple: they are fixed strings that -must occur in order. FileCheck defaults to ignoring horizontal whitespace -differences (e.g. a space is allowed to match a tab) but otherwise, the contents -of the CHECK: line is required to match some thing in the test file exactly. - -One nice thing about FileCheck (compared to grep) is that it allows merging -test cases together into logical groups. For example, because the test above -is checking for the "sub1:" and "inc4:" labels, it will not match unless there -is a "subl" in between those labels. If it existed somewhere else in the file, -that would not count: "grep subl" matches if subl exists anywhere in the -file. - - - -=head2 The FileCheck -check-prefix option - -The FileCheck -check-prefix option allows multiple test configurations to be -driven from one .ll file. This is useful in many circumstances, for example, -testing different architectural variants with llc. Here's a simple example: - - ; RUN: llvm-as < %s | llc -mtriple=i686-apple-darwin9 -mattr=sse41 \ - ; RUN: | FileCheck %s -check-prefix=X32> - ; RUN: llvm-as < %s | llc -mtriple=x86_64-apple-darwin9 -mattr=sse41 \ - ; RUN: | FileCheck %s -check-prefix=X64> - - define <4 x i32> @pinsrd_1(i32 %s, <4 x i32> %tmp) nounwind { - %tmp1 = insertelement <4 x i32>; %tmp, i32 %s, i32 1 - ret <4 x i32> %tmp1 - ; X32: pinsrd_1: - ; X32: pinsrd $1, 4(%esp), %xmm0 - - ; X64: pinsrd_1: - ; X64: pinsrd $1, %edi, %xmm0 - } - -In this case, we're testing that we get the expected code generation with -both 32-bit and 64-bit code generation. - - - -=head2 The "CHECK-NEXT:" directive - -Sometimes you want to match lines and would like to verify that matches -happen on exactly consecutive lines with no other lines in between them. In -this case, you can use CHECK: and CHECK-NEXT: directives to specify this. If -you specified a custom check prefix, just use "<PREFIX>-NEXT:". For -example, something like this works as you'd expect: - - define void @t2(<2 x double>* %r, <2 x double>* %A, double %B) { - %tmp3 = load <2 x double>* %A, align 16 - %tmp7 = insertelement <2 x double> undef, double %B, i32 0 - %tmp9 = shufflevector <2 x double> %tmp3, - <2 x double> %tmp7, - <2 x i32> < i32 0, i32 2 > - store <2 x double> %tmp9, <2 x double>* %r, align 16 - ret void - - ; CHECK: t2: - ; CHECK: movl 8(%esp), %eax - ; CHECK-NEXT: movapd (%eax), %xmm0 - ; CHECK-NEXT: movhpd 12(%esp), %xmm0 - ; CHECK-NEXT: movl 4(%esp), %eax - ; CHECK-NEXT: movapd %xmm0, (%eax) - ; CHECK-NEXT: ret - } - -CHECK-NEXT: directives reject the input unless there is exactly one newline -between it an the previous directive. A CHECK-NEXT cannot be the first -directive in a file. - - - -=head2 The "CHECK-NOT:" directive - -The CHECK-NOT: directive is used to verify that a string doesn't occur -between two matches (or before the first match, or after the last match). For -example, to verify that a load is removed by a transformation, a test like this -can be used: - - define i8 @coerce_offset0(i32 %V, i32* %P) { - store i32 %V, i32* %P - - %P2 = bitcast i32* %P to i8* - %P3 = getelementptr i8* %P2, i32 2 - - %A = load i8* %P3 - ret i8 %A - ; CHECK: @coerce_offset0 - ; CHECK-NOT: load - ; CHECK: ret i8 - } - - - -=head2 FileCheck Pattern Matching Syntax - -The CHECK: and CHECK-NOT: directives both take a pattern to match. For most -uses of FileCheck, fixed string matching is perfectly sufficient. For some -things, a more flexible form of matching is desired. To support this, FileCheck -allows you to specify regular expressions in matching strings, surrounded by -double braces: B<{{yourregex}}>. Because we want to use fixed string -matching for a majority of what we do, FileCheck has been designed to support -mixing and matching fixed string matching with regular expressions. This allows -you to write things like this: - - ; CHECK: movhpd {{[0-9]+}}(%esp), {{%xmm[0-7]}} - -In this case, any offset from the ESP register will be allowed, and any xmm -register will be allowed. - -Because regular expressions are enclosed with double braces, they are -visually distinct, and you don't need to use escape characters within the double -braces like you would in C. In the rare case that you want to match double -braces explicitly from the input, you can use something ugly like -B<{{[{][{]}}> as your pattern. - - - -=head2 FileCheck Variables - -It is often useful to match a pattern and then verify that it occurs again -later in the file. For codegen tests, this can be useful to allow any register, -but verify that that register is used consistently later. To do this, FileCheck -allows named variables to be defined and substituted into patterns. Here is a -simple example: - - ; CHECK: test5: - ; CHECK: notw [[REGISTER:%[a-z]+]] - ; CHECK: andw {{.*}}[REGISTER]] - -The first check line matches a regex (B<%[a-z]+>) and captures it into -the variable "REGISTER". The second line verifies that whatever is in REGISTER -occurs later in the file after an "andw". FileCheck variable references are -always contained in B<[[ ]]> pairs, are named, and their names can be -formed with the regex "B<[a-zA-Z_][a-zA-Z0-9_]*>". If a colon follows the -name, then it is a definition of the variable, if not, it is a use. - -FileCheck variables can be defined multiple times, and uses always get the -latest value. Note that variables are all read at the start of a "CHECK" line -and are all defined at the end. This means that if you have something like -"B<CHECK: [[XYZ:.*]]x[[XYZ]]>", the check line will read the previous -value of the XYZ variable and define a new one after the match is performed. If -you need to do something like this you can probably take advantage of the fact -that FileCheck is not actually line-oriented when it matches, this allows you to -define two separate CHECK lines that match on the same line. - - - -=head1 AUTHORS - -Maintained by The LLVM Team (L<http://llvm.org/>). - -=cut diff --git a/docs/CommandGuide/Makefile b/docs/CommandGuide/Makefile deleted file mode 100644 index 3f9f60b..0000000 --- a/docs/CommandGuide/Makefile +++ /dev/null @@ -1,103 +0,0 @@ -##===- docs/CommandGuide/Makefile --------------------------*- Makefile -*-===## -# -# The LLVM Compiler Infrastructure -# -# This file is distributed under the University of Illinois Open Source -# License.

B<lit> is -designed to be a lightweight testing tool with as simple a user interface as -possible. - -B<lit> should be run with one or more I<tests> to run specified on the command -line. Tests can be either individual test files or directories to search for -tests (see L<"TEST DISCOVERY">). - -Each specified test will be executed (potentially in parallel) and once all -tests have been run B<lit> will print summary information on the number of tests -which passed or failed (see L<"TEST STATUS RESULTS">). The B<lit> program will -execute with a non-zero exit code if any tests fail. - -By default B<lit> will use a succinct progress display and will only print -summary information for test failures. See L<"OUTPUT OPTIONS"> for options -controlling the B<lit> progress display and output. - -B<lit> also includes a number of options for controlling how tests are executed -(specific features may depend on the particular test format). See L<"EXECUTION -OPTIONS"> for more information. - -Finally, B<lit> also supports additional options for only running a subset of -the options specified on the command line, see L<"SELECTION OPTIONS"> for -more information. - -Users interested in the B<lit> architecture or designing a B<lit> testing -implementation should see L<"LIT INFRASTRUCTURE"> - -=head1 GENERAL OPTIONS - -=over - -=item B<-h>, B<--help> - -Show the B<lit> help message. - -=item B<-j> I<N>, B<--threads>=I<N> - -Run I<N> tests in parallel. By default, this is automatically chosen to match -the number of detected available CPUs. - -=item B<--config-prefix>=I<NAME> - -Search for I<NAME.cfg> and I<NAME.site.cfg> when searching for test suites, -instead of I<lit.cfg> and I<lit.site.cfg>. - -=item B<--param> I<NAME>, B<--param> I<NAME>=I<VALUE> - -Add a user defined parameter I<NAME> with the given I<VALUE> (or the empty -string if not given). The meaning and use of these parameters is test suite -dependent. - -=back - -=head1 OUTPUT OPTIONS - -=over - -=item B<-q>, B<--quiet> - -Suppress any output except for test failures. - -=item B<-s>, B<--succinct> - -Show less output, for example don't show information on tests that pass. - -=item B<-v>, B<--verbose> - -Show more information on test failures, for example the entire test output -instead of just the test result. - -=item B<--no-progress-bar> - -Do not use curses based progress bar. - -=back - -=head1 EXECUTION OPTIONS - -=over - -=item B<--path>=I<PATH> - -Specify an addition I<PATH> to use when searching for executables in tests. - -=item B<--vg> - -Run individual tests under valgrind (using the memcheck tool). The -I<--error-exitcode> argument for valgrind is used so that valgrind failures will -cause the program to exit with a non-zero status. - -=item B<--vg-arg>=I<ARG> - -When I<--vg> is used, specify an additional argument to pass to valgrind itself. - -=item B<--time-tests> - -Track the wall time individual tests take to execute and includes the results in -the summary output. This is useful for determining which tests in a test suite -take the most time to execute. Note that this option is most useful with I<-j -1>. - -=back - -=head1 SELECTION OPTIONS - -=over - -=item B<--max-tests>=I<N> - -Run at most I<N> tests and then terminate. - -=item B<--max-time>=I<N> - -Spend at most I<N> seconds (approximately) running tests and then terminate. - -=item B<--shuffle> - -Run the tests in a random order. - -=back - -=head1 ADDITIONAL OPTIONS - -=over - -=item B<--debug> - -Run B<lit> in debug mode, for debugging configuration issues and B<lit> itself. - -=item B<--show-suites> - -List the discovered test suites as part of the standard output. - -=item B<--no-tcl-as-sh> - -Run Tcl scripts internally (instead of converting to shell scripts). - -=item B<--repeat>=I<N> - -Run each test I<N> times. Currently this is primarily useful for timing tests, -other results are not collated in any reasonable fashion. - -=back - -=head1 EXIT STATUS - -B<lit> will exit with an exit code of 1 if there are any FAIL or XPASS -results. Otherwise, it will exit with the status 0. Other exit codes are used -for non-test related failures (for example a user error or an internal program -error). - -=head1 TEST DISCOVERY - -The inputs passed to B<lit> can be either individual tests, or entire -directories or hierarchies of tests to run. When B<lit> starts up, the first -thing it does is convert the inputs into a complete list of tests to run as part -of I<test discovery>. - -In the B<lit> model, every test must exist inside some I<test suite>. B<lit> -resolves the inputs specified on the command line to test suites by searching -upwards from the input path until it finds a I<lit.cfg> or I<lit.site.cfg> -file. These files serve as both a marker of test suites and as configuration -files which B<lit> loads in order to understand how to find and run the tests -inside the test suite. - -Once B<lit> has mapped the inputs into test suites it traverses the list of -inputs adding tests for individual files and recursively searching for tests in -directories. - -This behavior makes it easy to specify a subset of tests to run, while still -allowing the test suite configuration to control exactly how tests are -interpreted. In addition, B<lit> always identifies tests by the test suite they -are in, and their relative path inside the test suite. For appropriately -configured projects, this allows B<lit> to provide convenient and flexible -support for out-of-tree builds. - -=head1 TEST STATUS RESULTS - -Each test ultimately produces one of the following six results: - -=over - -=item B<PASS> - -The test succeeded. - -=item B<XFAIL> - -The test failed, but that is expected. This is used for test formats which allow -specifying that a test does not currently work, but wish to leave it in the test -suite. - -=item B<XPASS> - -The test succeeded, but it was expected to fail. This is used for tests which -were specified as expected to fail, but are now succeeding (generally because -the feature they test was broken and has been fixed). - -=item B<FAIL> - -The test failed. - -=item B<UNRESOLVED> - -The test result could not be determined. For example, this occurs when the test -could not be run, the test itself is invalid, or the test was interrupted. - -=item B<UNSUPPORTED> - -The test is not supported in this environment. This is used by test formats -which can report unsupported tests. - -=back - -Depending on the test format tests may produce additional information about -their status (generally only for failures). See the L<Output|"OUTPUT OPTIONS"> -section for more information. - -=head1 LIT INFRASTRUCTURE - -This section describes the B<lit> testing architecture for users interested in -creating a new B<lit> testing implementation, or extending an existing one. - -B<lit> proper is primarily an infrastructure for discovering and running -arbitrary tests, and to expose a single convenient interface to these -tests. B<lit> itself doesn't know how to run tests, rather this logic is -defined by I<test suites>. - -=head2 TEST SUITES - -As described in L<"TEST DISCOVERY">, tests are always located inside a I<test -suite>. Test suites serve to define the format of the tests they contain, the -logic for finding those tests, and any additional information to run the tests. - -B<lit> identifies test suites as directories containing I<lit.cfg> or -I<lit.site.cfg> files (see also B<--config-prefix>). Test suites are initially -discovered by recursively searching up the directory hierarchy for all the input -files passed on the command line. You can use B<--show-suites> to display the -discovered test suites at startup. - -Once a test suite is discovered, its config file is loaded. Config files -themselves are Python modules which will be executed. When the config file is -executed, two important global variables are predefined: - -=over - -=item B<lit> - -The global B<lit> configuration object (a I<LitConfig> instance), which defines -the builtin test formats, global configuration parameters, and other helper -routines for implementing test configurations. - -=item B<config> - -This is the config object (a I<TestingConfig> instance) for the test suite, -which the config file is expected to populate. The following variables are also -available on the I<config> object, some of which must be set by the config and -others are optional or predefined: - -B<name> I<[required]> The name of the test suite, for use in reports and -diagnostics. - -B<test_format> I<[required]> The test format object which will be used to -discover and run tests in the test suite. Generally this will be a builtin test -format available from the I<lit.formats> module. - -B<test_src_root> The filesystem path to the test suite root. For out-of-dir -builds this is the directory that will be scanned for tests. - -B<test_exec_root> For out-of-dir builds, the path to the test suite root inside -the object directory. This is where tests will be run and temporary output files -placed. - -B<environment> A dictionary representing the environment to use when executing -tests in the suite. - -B<suffixes> For B<lit> test formats which scan directories for tests, this -variable is a list of suffixes to identify test files. Used by: I<ShTest>, -I<TclTest>. - -B<substitutions> For B<lit> test formats which substitute variables into a test -script, the list of substitutions to perform. Used by: I<ShTest>, I<TclTest>. - -B<unsupported> Mark an unsupported directory, all tests within it will be -reported as unsupported. Used by: I<ShTest>, I<TclTest>. - -B<parent> The parent configuration, this is the config object for the directory -containing the test suite, or None. - -B<root> The root configuration. This is the top-most B<lit> configuration in -the project. - -B<on_clone> The config is actually cloned for every subdirectory inside a test -suite, to allow local configuration on a per-directory basis. The I<on_clone> -variable can be set to a Python function which will be called whenever a -configuration is cloned (for a subdirectory). The function should takes three -arguments: (1) the parent configuration, (2) the new configuration (which the -I<on_clone> function will generally modify), and (3) the test path to the new -directory being scanned. - -=back - -=head2 TEST DISCOVERY - -Once test suites are located, B<lit> recursively traverses the source directory -(following I<test_src_root>) looking for tests. When B<lit> enters a -sub-directory, it first checks to see if a nested test suite is defined in that -directory. If so, it loads that test suite recursively, otherwise it -instantiates a local test config for the directory (see L<"LOCAL CONFIGURATION -FILES">). - -Tests are identified by the test suite they are contained within, and the -relative path inside that suite. Note that the relative path may not refer to an -actual file on disk; some test formats (such as I<GoogleTest>) define "virtual -tests" which have a path that contains both the path to the actual test file and -a subpath to identify the virtual test. - -=head2 LOCAL CONFIGURATION FILES - -When B<lit> loads a subdirectory in a test suite, it instantiates a local test -configuration by cloning the configuration for the parent direction -- the root -of this configuration chain will always be a test suite. Once the test -configuration is cloned B<lit> checks for a I<lit.local.cfg> file in the -subdirectory. If present, this file will be loaded and can be used to specialize -the configuration for each individual directory. This facility can be used to -define subdirectories of optional tests, or to change other configuration -parameters -- for example, to change the test format, or the suffixes which -identify test files. - -=head2 TEST RUN OUTPUT FORMAT - -The b<lit> output for a test run conforms to the following schema, in both short -and verbose modes (although in short mode no PASS lines will be shown). This -schema has been chosen to be relatively easy to reliably parse by a machine (for -example in buildbot log scraping), and for other tools to generate. - -Each test result is expected to appear on a line that matches: - -<result code>: <test name> (<progress info>) - -where <result-code> is a standard test result such as PASS, FAIL, XFAIL, XPASS, -UNRESOLVED, or UNSUPPORTED. The performance result codes of IMPROVED and -REGRESSED are also allowed. - -The <test name> field can consist of an arbitrary string containing no newline. - -The <progress info> field can be used to report progress information such as -(1/300) or can be empty, but even when empty the parentheses are required. - -Each test result may include additional (multiline) log information in the -following format. - -<log delineator> TEST '(<test name>)' <trailing delineator> -... log message ... -<log delineator> - -where <test name> should be the name of a preceeding reported test, <log -delineator> is a string of '*' characters I<at least> four characters long (the -recommended length is 20), and <trailing delineator> is an arbitrary (unparsed) -string. - -The following is an example of a test run output which consists of four tests A, -B, C, and D, and a log message for the failing test C. - -=head3 Example Test Run Output Listing - -PASS: A (1 of 4) -PASS: B (2 of 4) -FAIL: C (3 of 4) -******************** TEST 'C' FAILED ******************** -Test 'C' failed as a result of exit code 1. -******************** -PASS: D (4 of 4) - -=back - -=head2 LIT EXAMPLE TESTS - -The B<lit> distribution contains several example implementations of test suites -in the I<ExampleTests> directory. - -=head1 SEE ALSO - -L<valgrind(1)> - -=head1 AUTHOR - -Written by Daniel Dunbar and maintained by the LLVM Team (L<http://llvm.org/>). - -=cut diff --git a/docs/CommandGuide/llc.pod b/docs/CommandGuide/llc.pod deleted file mode 100644 index 35abdae..0000000 --- a/docs/CommandGuide/llc.pod +++ /dev/null @@ -1,201 +0,0 @@ -=pod - -=head1 NAME - -llc - LLVM static compiler - -=head1 SYNOPSIS - -B<llc> [I<options>] [I<filename>] - -=head1 DESCRIPTION - -The B<llc> command compiles LLVM source inputs into assembly language for a -specified architecture.

It -archives several files together into a single file. The intent for this is -to produce archive libraries by LLVM bitcode that can be linked into an -LLVM program. However, the archive can contain any kind of file. By default, -B<llvm-ar> 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. - -The B<llvm-ar> command can be used to I<read> both SVR4 and BSD style archive -files. However, it cannot be used to write them. While the B<llvm-ar> command -produces files that are I<almost> identical to the format used by other C<ar> -implementations, it has two significant departures in order to make the -archive appropriate for LLVM. The first departure is that B<llvm-ar> only -uses BSD4.4 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 B<llvm-ar> usually won't be readable or editable with any -C<ar> implementation or useful for linking. Using the C<f> modifier to flatten -file names will make the archive readable by other C<ar> implementations -but not for linking because the symbol table format for LLVM is unique. If an -SVR4 or BSD style archive is used with the C<r> (replace) or C<q> (quick -update) operations, the archive will be reconstructed in LLVM format. This -means that the string table will be dropped (in deference to BSD 4.4 long names) -and an LLVM symbol table will be added (by default). The system symbol table -will be retained. - -Here's where B<llvm-ar> departs from previous C<ar> implementations: - -=over - -=item I<Symbol Table> - -Since B<llvm-ar> is intended to archive bitcode files, the symbol table -won't make much sense to anything but LLVM. 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 LSB 4byte integer and a null-terminated -string. - -=item I<Long Paths> - -Some C<ar> implementations (SVR4) use a separate file member to record long -path names (> 15 characters). B<llvm-ar> takes the BSD 4.4 and Mac OS 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. - -=item I<Compression> - -B<llvm-ar> 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 LLVM Compressor utility makes. It generally favors bzip2 but will select -between "no compression" or bzip2 depending on what makes sense for the -file's content. - -=item I<Directory Recursion> - -Most C<ar> implementations do not recurse through directories but simply -ignore directories if they are presented to the program in the F<files> -option. B<llvm-ar>, however, can recurse through directory structures and -add all the files under a directory, if requested. - -=item I<TOC Verbose Output> - -When B<llvm-ar> prints out the verbose table of contents (C<tv> 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 LLVM bitcode file. An -'S' means the file is the symbol table. - -=back - -=head1 OPTIONS - -The options to B<llvm-ar> are compatible with other C<ar> implementations. -However, there are a few modifiers (F<zR>) that are not found in other -C<ar>s. The options to B<llvm-ar> 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 B<llvm-ar> should process the archive file. - -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 C<.a> suffix, but this is not required. Following -the F<archive-name> comes a list of F<files> that indicate the specific members -of the archive to operate on. If the F<files> option is not specified, it -generally means either "none" or "all" members, depending on the operation. - -=head2 Operations - -=over - -=item d - -Delete files from the archive. No modifiers are applicable to this operation. -The F<files> 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 F<files> are specified, the archive is not modified. - -=item m[abi] - -Move files from one location in the archive to another. The F<a>, F<b>, and -F<i> modifiers apply to this operation. The F<files> 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 F<files> are specified, the -archive is not modified. - -=item p[k] - -Print files to the standard output. The F<k> modifier applies to this -operation. This operation simply prints the F<files> indicated to the -standard output. If no F<files> are specified, the entire archive is printed. -Printing bitcode files is ill-advised as they might confuse your terminal -settings. The F<p> operation never modifies the archive. - -=item q[Rfz] - -Quickly append files to the end of the archive. The F<R>, F<f>, and F<z> -modifiers apply to this operation. This operation quickly adds the -F<files> to the archive without checking for duplicates that should be -removed first. If no F<files> are specified, the archive is not modified. -Because of the way that B<llvm-ar> constructs the archive file, its dubious -whether the F<q> operation is any faster than the F<r> operation. - -=item r[Rabfuz] - -Replace or insert file members. The F<R>, F<a>, F<b>, F<f>, F<u>, and F<z> -modifiers apply to this operation. This operation will replace existing -F<files> or insert them at the end of the archive if they do not exist. If no -F<files> are specified, the archive is not modified. - -=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 F<v> modifier, -B<llvm-ar> also prints out the file type (B=bitcode, Z=compressed, S=symbol -table, blank=regular file), the permission mode, the owner and group, the -size, and the date. If any F<files> are specified, the listing is only for -those files. If no F<files> are specified, the table of contents for the -whole archive is printed. - -=item x[oP] - -Extract archive members back to files. The F<o> modifier applies to this -operation. This operation retrieves the indicated F<files> from the archive -and writes them back to the operating system's file system. If no -F<files> are specified, the entire archive is extract. - -=back - -=head2 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. - -=over - -=item [a] - -When inserting or moving member files, this option specifies the destination of -the new files as being C<a>fter the F<relpos> member. If F<relpos> is not found, -the files are placed at the end of the archive. - -=item [b] - -When inserting or moving member files, this option specifies the destination of -the new files as being C<b>efore the F<relpos> member. If F<relpos> is not -found, the files are placed at the end of the archive. This modifier is -identical to the the F<i> modifier. - -=item [f] - -Normally, B<llvm-ar> 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 C<ar> but may also -thwart correct extraction of the files (duplicates may overwrite). If used with -the F<R> option, the directory recursion will be performed but the file names -will all be C<f>lattened to simple file names. - -=item [i] - -A synonym for the F<b> option. - -=item [k] - -Normally, B<llvm-ar> will not print the contents of bitcode files when the -F<p> operation is used. This modifier defeats the default and allows the -bitcode members to be printed. - -=item [N] - -This option is ignored by B<llvm-ar> but provided for compatibility. - -=item [o] - -When extracting files, this option will cause B<llvm-ar> to preserve the -original modification times of the files it writes. - -=item [P] - -use full path names when matching - -=item [R] - -This modifier instructions the F<r> option to recursively process directories. -Without F<R>, directories are ignored and only those F<files> that refer to -files will be added to the archive. When F<R> is used, any directories specified -with F<files> 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. - -=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. - -=item [z] - -When inserting or replacing any file in the archive, compress the file first. -This -modifier is safe to use when (previously) compressed bitcode files are added to -the archive; the compressed bitcode files will not be doubly compressed. - -=back - -=head2 Modifiers (generic) - -The modifiers below may be applied to any operation. - -=over - -=item [c] - -For all operations, B<llvm-ar> will always create the archive if it doesn't -exist. Normally, B<llvm-ar> will print a warning message indicating that the -archive is being created. Using this modifier turns off that warning. - -=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 -bitcode files in the archive. Using this modifier is more efficient that using -L<llvm-ranlib|llvm-ranlib> which also creates the symbol table. - -=item [S] - -This modifier is the opposite of the F<s> modifier. It instructs B<llvm-ar> to -not build the symbol table. If both F<s> and F<S> are used, the last modifier to -occur in the options will prevail. - -=item [v] - -This modifier instructs B<llvm-ar> 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. - -=back - -=head1 STANDARDS - -The B<llvm-ar> utility is intended to provide a superset of the IEEE Std 1003.2 -(POSIX.2) functionality for C<ar>. B<llvm-ar> can read both SVR4 and BSD4.4 (or -Mac OS X) archives. If the C<f> modifier is given to the C<x> or C<r> operations -then B<llvm-ar> will write SVR4 compatible archives. Without this modifier, -B<llvm-ar> will write BSD4.4 compatible archives that have long names -immediately after the header and indicated using the "#1/ddd" notation for the -name in the header. - -=head1 FILE FORMAT - -The file format for LLVM Archive files is similar to that of BSD 4.4 or Mac OSX -archive files. In fact, except for the symbol table, the C<ar> commands on those -operating systems should be able to read LLVM archive files. The details of the -file format follow. - -Each archive begins with the archive magic number which is the eight printable -characters "!<arch>\n" where \n 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 \n padding character if necessary -(to make the length even). Each file member is composed of a header (defined -below), an optional newline-terminated "long file name" and the contents of -the file. - -The fields of the header are described in the items below. All fields of the -header contain only ASCII characters, are left justified and are right padded -with space characters. - -=over - -=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 C<#1/nnn> where C<nnn> provides the length of the name and the C<#1/> -is literal. In this case, the actual name of the file is provided in the C<nnn> -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. - -=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. - -=item uid - char[6] - -This field provides the user id of the file encoded as a decimal ASCII 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 stat(2) -operating system call. - -=item gid - char[6] - -This field provides the group id of the file encoded as a decimal ASCII 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 stat(2) -operating system call. - -=item mode - char[8] - -This field provides the access mode of the file encoded as an octal ASCII -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 -stat(2) operating system call. - -=item size - char[10] - -This field provides the size of the file, in bytes, encoded as a decimal ASCII -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. - -=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. - -=back - -The LLVM symbol table has the special name "#_LLVM_SYM_TAB_#". It is presumed -that no regular archive member file will want this name. The LLVM 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: - -=over - -=item offset - vbr encoded 32-bit integer - -The offset item provides the offset into the archive file where the bitcode -member is stored that is associated with the symbol. The offset value is 0 -based at the start of the first "normal" 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. - -=item length - vbr encoded 32-bit integer - -The length item provides the length of the symbol that follows. Like this -I<offset> item, the length is variable bit rate encoded. - -=item symbol - character array - -The symbol item provides the text of the symbol that is associated with the -I<offset>. The symbol is not terminated by any character. Its length is provided -by the I<length> 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. - -=back - -=head1 EXIT STATUS - -If B<llvm-ar> succeeds, it will exit with 0. A usage error, results -in an exit code of 1.

It takes LLVM -source files as input, runs the specified optimizations or analyses on it, and then -outputs the optimized file or the analysis results. The function of -B<opt> depends on whether the B<-analyze> option is given. - -When B<-analyze> is specified, B<opt> performs various analyses of the input -source. 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. - -While B<-analyze> is I<not> given, B<opt> attempts to produce an optimized -output file. The optimizations available via B<opt> depend upon what -libraries were linked into it as well as any additional libraries that have -been loaded with the B<-load> option. Use the B<-help> option to determine -what optimizations you can use. - -If I<filename> is omitted from the command line or is I<->, B<opt> reads its -input from standard input. Inputs can be in either the LLVM assembly language -format (.ll) or the LLVM bitcode format (.bc). - -If an output filename is not specified with the B<-o> option, B<opt> -writes its output to the standard output. - -=head1 OPTIONS - -=over - -=item B<-f> - -Enable binary output on terminals. Normally, B<opt> will refuse to -write raw bitcode output if the output stream is a terminal. With this option, -B<opt> will write raw bitcode regardless of the output device. - -=item B<-help> - -Print a summary of command line options. - -=item B<-o> I<filename> - -Specify the output filename. - -=item B<-S> - -Write output in LLVM intermediate language (instead of bitcode). - -=item B<-{passname}> - -B<opt> provides the ability to run any of LLVM's optimization or analysis passes -in any order. The B<-help> 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). - -=item B<-std-compile-opts> - -This is short hand for a standard list of I<compile time optimization> 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: - - llvm-as < /dev/null | opt -std-compile-opts -disable-output -debug-pass=Arguments - -=item B<-disable-inlining> - -This option is only meaningful when B<-std-compile-opts> is given. It simply -removes the inlining pass from the standard list. - -=item B<-disable-opt> - -This option is only meaningful when B<-std-compile-opts> is given. It disables -most, but not all, of the B<-std-compile-opts>. The ones that remain are -B<-verify>, B<-lower-setjmp>, and B<-funcresolve>. - -=item B<-strip-debug> - -This option causes opt to strip debug information from the module before -applying other optimizations. It is essentially the same as B<-strip> but it -ensures that stripping of debug information is done first. - -=item B<-verify-each> - -This option causes opt to add a verify pass after every pass otherwise specified -on the command line (including B<-verify>). 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 B<-std-compile-opts> and B<-verify-each> -can quickly track down this kind of problem. - -=item B<-profile-info-file> I<filename> - -Specify the name of the file loaded by the -profile-loader option. - -=item B<-stats> - -Print statistics. - -=item B<-time-passes> - -Record the amount of time needed for each pass and print it to standard -error. - -=item B<-debug> - -If this is a debug build, this option will enable debug printouts -from passes which use the I<DEBUG()> macro. See the B<LLVM Programmer's -Manual>, section I<#DEBUG> for more information. - -=item B<-load>=I<plugin> - -Load the dynamic object I<plugin>. 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.
