LLVM provides functionality to time optimization and analysis passes.
New Pass Manager APIs
=====================
See :meth:`PassBuilder.start_pass_timing` and
:meth:`PassBuilder.finish_pass_timing` in :doc:`optimization-passes`.
Legacy Pass Manager APIs
========================
.. function:: set_time_passes(enable)
Enable or disable the pass timers.
.. function:: report_and_reset_timings()
Returns the pass timings report and resets the LLVM internal timers.
Pass timers are enabled by ``set_time_passes()``. If the timers are not
enabled, this function will return an empty string.
