COMMANDS -------- * `merge <profdata_merge_>`_ * `show <profdata_show_>`_ .. program:: llvm-profdata merge .. _profdata_merge: MERGE ----- SYNOPSIS ^^^^^^^^ :program:`llvm-profdata merge` [*options*] [*filenames...*] DESCRIPTION ^^^^^^^^^^^ :program:`llvm-profdata merge` takes several profile data files generated by PGO instrumentation and merges them together into a single indexed profile data file. OPTIONS ^^^^^^^ .. option:: -help Print a summary of command line options. .. option:: -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. .. program:: llvm-profdata show .. _profdata_show: SHOW ---- SYNOPSIS ^^^^^^^^ :program:`llvm-profdata show` [*options*] [*filename*] DESCRIPTION ^^^^^^^^^^^ :program:`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 ^^^^^^^ .. option:: -all-functions Print details for every function. .. option:: -counts Print the counter values for the displayed functions. .. option:: -function=string Print details for a function if the function's name contains the given string. .. option:: -help Print a summary of command line options. .. option:: -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.
