The llvm-profdata tool is a small utility for working with profile data files.

llvm-profdata merge [options] [filenames...]
llvm-profdata merge takes several profile data files generated by PGO instrumentation and merges them together into a single indexed profile data file.
-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.
llvm-profdata show [options] [filename]
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.
-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.
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.
