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.
