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.
|
|
|
|
.. option:: -instr (default)
|
|
|
|
Specify that the input profile is an instrumentation-based profile.
|
|
|
|
.. option:: -sample
|
|
|
|
Specify that the input profile is a sample-based profile. When using
|
|
sample-based profiles, the format of the generated file can be generated
|
|
in one of three ways:
|
|
|
|
.. option:: -binary (default)
|
|
|
|
Emit the profile using a binary encoding.
|
|
|
|
.. option:: -text
|
|
|
|
Emit the profile in text mode.
|
|
|
|
.. option:: -gcc
|
|
|
|
Emit the profile using GCC's gcov format (Not yet supported).

DESCRIPTION
|
|
^^^^^^^^^^^
|
|
|
|
:program:`llvm-profdata show` takes a profile data file and displays the
|
|
information about the profile counters for this file and
|
|
