llvm-remarkutil - Remark utility
================================
.. program:: llvm-remarkutil
SYNOPSIS
--------
:program:`llvm-remarkutil` [*subcommmand*] [*options*]
DESCRIPTION
-----------
Utility for displaying information from, and converting between different
`remark <https://llvm.org/docs/Remarks.html>`_ formats.
Subcommands
-----------
* :ref:`bitstream2yaml_subcommand` - Reserialize bitstream remarks to YAML.
* :ref:`yaml2bitstream_subcommand` - Reserialize YAML remarks to bitstream.
* :ref:`instruction-count_subcommand` - Output function instruction counts.
.. _bitstream2yaml_subcommand:
bitstream2yaml
~~~~~~~~~~~~~~
.. program:: llvm-remarkutil bitstream2yaml
USAGE: :program:`llvm-remarkutil` bitstream2yaml <input file> -o <output file>
Summary
^^^^^^^
Takes a bitstream remark file as input, and reserializes that file as YAML.
.. _yaml2bitstream_subcommand:
yaml2bitstream
~~~~~~~~~~~~~~
.. program:: llvm-remarkutil yaml2bitstream
USAGE: :program:`llvm-remarkutil` yaml2bitstream <input file> -o <output file>
Summary
^^^^^^^
Takes a YAML remark file as input, and reserializes that file in the bitstream
format.
.. _instruction-count_subcommand:
instruction-count
~~~~~~~~~~~~~~~~~
.. program:: llvm-remarkutil instruction-count
USAGE: :program:`llvm-remarkutil` instruction-count <input file> --parser=<bitstream|yaml> -o <output file>
Summary
^^^^^^^
Outputs instruction count remarks for every function. Instruction count remarks
encode the number of instructions in a function at assembly printing time.
Instruction count remarks require asm-printer remarks.
CSV format is as follows:
::
Function,InstructionCount
foo,123
