Subject: glsl: Add IR builder support for triops.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=eff2ca1ac3f77da81a698b08c46f245b28930ede;p=mesa.git

glsl: Add IR builder support for triops.

Now that we have the ir_expression constructor that does type inference,
this is trivial to do.
