NAME¶
llvm-profdata - Profile data tool
SYNOPSIS¶
llvm-profdata command [args...]
DESCRIPTION¶
The llvm-profdata tool is a small utility for working with profile data files.
COMMANDS¶
- merge
- show
MERGE¶
SYNOPSIS¶
llvm-profdata merge [options] [filenames...]
DESCRIPTION¶
llvm-profdata merge takes several profile data files generated by PGO instrumentation and merges them together into a single indexed profile data file.
OPTIONS¶
- -help
- Print a summary of command line options.
- -output=output, -o=output
- Specify the output file name. Output cannot be - as the resulting indexed profile data can't be written to standard output.
- -instr (default)
- Specify that the input profile is an instrumentation-based profile.
- -sample
- Specify that the input profile is a sample-based profile. When using sample-based profiles, the format of the generated file can be generated in one of three ways:
Emit the profile using a binary encoding.
Emit the profile in text mode.
Emit the profile using GCC's gcov format (Not yet supported).
SHOW¶
SYNOPSIS¶
llvm-profdata show [options] [filename]
DESCRIPTION¶
llvm-profdata show takes a profile data file and displays the information about the profile counters for this file and for any of the specified function(s).
If filename is omitted or is -, then llvm-profdata show reads its input from standard input.
OPTIONS¶
- -all-functions
- Print details for every function.
- -counts
- Print the counter values for the displayed functions.
- -function=string
- Print details for a function if the function's name contains the given string.
- -help
- Print a summary of command line options.
- -output=output, -o=output
- Specify the output file name. If output is - or it isn't specified, then the output is sent to standard output.
- -instr (default)
- Specify that the input profile is an instrumentation-based profile.
- -sample
- Specify that the input profile is a sample-based profile.
EXIT STATUS¶
llvm-profdata returns 1 if the command is omitted or is invalid, if it cannot read input files, or if there is a mismatch between their data.
