llvm-profgen - LLVM SPGO profile generation tool
|
|
================================================
|
|
|
|
.. program:: llvm-profgen
|
|
|
|
SYNOPSIS
|
|
--------
|
|
|
|
:program:`llvm-profgen` [*commands*] [*options*]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
The :program:`llvm-profgen` utility generates a profile data file
|
|
from given perf script data files for sample-based profile guided
|
|
optimization(SPGO).
|
|
|
|
COMMANDS
|
|
--------
|
|
At least one of the following commands are required:
|
|
|
|
.. option:: --perfscript=<string[,string,...]>
|
|
|
|
Path of perf-script trace created by Linux perf tool with `script`
|
|
command(the raw perf.data should be profiled with -b).
|
|
|
|
.. option:: --etm=<string>
|
|
|
|
Path of the ETM trace file created by ARM CoreSight trace tools.
|
|
Requires the OpenCSD library version 1.5.4 or higher to be enabled during the build.
|
|
|
|
.. option:: --perfdata=<perfdata>, --pd
|
|
|
|
Path of raw perf data created by Linux perf tool (it should be profiled
|
|
with -b).
|
|
|
|
.. option:: --unsymbolized-profile=<unsymbolized profile>, --up
|
|
|
|
Path of the unsymbolized profile created by ``llvm-profgen`` with
|
|
``--skip-symbolization``.
|
|
|
|
.. option:: --llvm-sample-profile=<llvm sample profile>
|
|
|
|
Path of the LLVM sample profile.
|
|
|
|
.. note::
|
|
|
|
Only one of ``--perfscript``, ``--perfdata``, ``--unsymbolized-profile``,
|
|
``--llvm-sample-profile``, or ``--etm`` may be specified at a time.
|
|
|
|
.. option:: --binary=<string[,string,...]>
|
|
|
|
Path of the input profiled binary files.
|
|
|
|
.. option:: --output=<string>
|
|
|
|
Path of the output profile file.
|
|
|
|
|
|
OPTIONS
|
|
-------
|
|
:program:`llvm-profgen` supports the following options:
|
|
|
|
.. option:: --format=[text|binary|extbinary|compbinary|gcc]
|
|
|
|
Specify the format of the generated profile. Supported <format> are `text`,
|
|
`binary`, `extbinary`, `compbinary`, `gcc`, see `llvm-profdata` for more
|
|
descriptions of the format.
|
|
|
|
.. option:: --show-mmap-events
|
|
|
|
Print mmap events.
|
|
|
|
.. option:: --show-disassembly
|
|
|
|
Print disassembled code.
|
|
|
|
.. option:: --x86-asm-syntax=[att|intel]
|
|
|
|
Specify whether to print assembly code in AT&T syntax (the default) or Intel
|
|
syntax.
|
|
|
|
.. option:: --debug-binary=<debug-binary>
|
|
|
|
Path of debug info binary. ``llvm-profgen`` will load the DWARF info from
|
|
it instead of the executable binary.
|
|
|
|
.. option:: --target-triple=<triple>
|
|
|
|
Override the target triple for the binary. This is useful for ETM trace
|
|
decoding to specify the correct Arm M-profile target.
|
|
|
|
.. option:: --pid
|
|
|
|
Process Id for the profiled executable binary.
|
|
|
|
.. option:: --output=<output>
|
|
|
|
Path of the output profile file.
|
|
|
|
.. option:: --data-access-perftrace=<data-access-perftrace>
|
|
|
|
File path of a Linux perf raw trace (generated by ``perf report -D``)
|
|
consisting of memory access events.
