   SYNOPSIS
       llvm-profdata merge [options] [filenames...]

   DESCRIPTION
       llvm-profdata merge takes several profile data files generated  by  PGO

       -help  Print a summary of command line options.

       -output=output, -o=output
              Specify the output file name.  Output cannot be - as the result-

SHOW
   SYNOPSIS
       llvm-profdata show [options] [filename]

   DESCRIPTION
       llvm-profdata  show takes a profile data file and displays the informa-
       tion about the profile counters for this file and for any of the speci-

       If filename is omitted or is -, then llvm-profdata show reads its input

              Print details for every function.

       -counts
              Print the counter values for the displayed functions.

              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 speci-
              fied, 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.
