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
