Subject: i965: Set the source operand types for gen6 if/else/endif to integer.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6ea108e7db79cb7135a8a1ef216e25381f72c225;p=mesa.git

i965: Set the source operand types for gen6 if/else/endif to integer.

I don't think this should matter, but I'm not sure, and it's
recommended by a kernel checker in fulsim.
