Subject: glsl: Use accessors for ir_variable::warn_extension
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=baf5a756640fde8cd4d4e704ed8c9c45da3e5407;p=mesa.git

glsl: Use accessors for ir_variable::warn_extension

The payoff for this will come in the next patch.

No change Valgrind massif results for a trimmed apitrace of dota2.
