NAME
llvm-profgen - LLVM SPGO profile generation tool
SYNOPSIS
llvm-profgen [ commands ] [ options ]
DESCRIPTION
The 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:
--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).
--binary=<string[,string,...]>
Path of the input profiled binary files.
--output=<string>
Path of the output profile file.
OPTIONS
llvm-profgen
supports the following options:
--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.
--show-mmap-events
Print mmap events.
--show-disassembly
Print disassembled code.
--x86-asm-syntax=[att|intel]
Specify whether to print assembly code in AT&T syntax (the default) or Intel syntax.
