SYNOPSIS
^^^^^^^^
:program:`llvm-profdata merge` [*options*] [*filenames...*]
DESCRIPTION

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

: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

then the output is sent to standard output.
EXIT STATUS
