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:

              -binary (default)

              Emit the profile using a binary encoding.

              -text

              Emit the profile in text mode.

              -gcc

              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.
