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.
