Subject: ir_reader: Only validate IR when a global 'debug' flag is set.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9a3df46fbcfbad10163686ae4c034a3a55116947;p=mesa.git

ir_reader: Only validate IR when a global 'debug' flag is set.

This extra validation is very useful when working on the built-ins, but
in general overkill - the results should stay the same unless the
built-ins or ir_validate have changed.

Also, validating all the built-in functions in every test case makes
piglit run unacceptably slow.
