NAME

6       llvm-profgen - LLVM SPGO profile generation tool
7

SYNOPSIS

9       llvm-profgen [commands] [options]
10

DESCRIPTION

12       The  llvm-profgen utility generates a profile data file from given perf
13       script data files for sample-based profile guided optimization(SPGO).
14

COMMANDS

16       At least one of the following commands are required:
17
18       --perfscript=<string[,string,...]>
19              Path of perf-script trace created by Linux perf tool with script
20              command(the raw perf.data should be profiled with -b).
21
22       --binary=<string[,string,...]>
23              Path of the input profiled binary files.
24
25       --output=<string>
26              Path of the output profile file.
27

OPTIONS

29       llvm-profgen supports the following options:
30
31       --format=[text|binary|extbinary|compbinary|gcc]
32              Specify  the format of the generated profile. Supported <format>
33              are text, binary, extbinary, compbinary, gcc, see  llvm-profdata
34              for more descriptions of the format.
35
36       --show-mmap-events
37              Print mmap events.
38
39       --show-disassembly
40              Print disassembled code.
41
42       --x86-asm-syntax=[att|intel]
43              Specify  whether  to print assembly code in AT&T syntax (the de‐
44              fault) or Intel syntax.
