Subject: i965: tell GLSL compiler to emit code using condition codes
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a9e753c84cc5acc2a89686a5e4109f3b056d4fb4;p=mesa.git

i965: tell GLSL compiler to emit code using condition codes

The default for EmitCondCodes got flipped when gallium-0.2 was merged.
This fixes GLSL if/else/endif regressions.
Drivers that use GLSL should always explicitly set the flag to be safe.
