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.

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.

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.
