Subject: mesa/tests: Add simple, dumb test for _mesa_program_state_string
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=09ceed75872e15b175e362f8d0ea146a8c79ae08;p=mesa.git

mesa/tests: Add simple, dumb test for _mesa_program_state_string

After some discussions about the correct way to update
_mesa_program_state_string, I decided to make a unit test for the
function.  It turns out that the function didn't work quite the way I
thought.  The unit test proves that the code was already correct.
