Subject: builtins: Add the mix(gentype, gentype, float) variant.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f03acfc7d7275b60418fec94f4a7044de486a05c;p=mesa.git

builtins: Add the mix(gentype, gentype, float) variant.

The broken-in-mesa Regnum Online shader now parses, except for its
preprocessor usage.
