Subject: i965: Enable 64-bit GLSL extensions
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=406f603b347f554f9f796d22cb74dde48d6551d3;p=mesa.git

i965: Enable 64-bit GLSL extensions

Now that we have software implementations of ARB_gpu_shader_int64 and
ARB_gpu_shader_fp64 we can unconditionally enable these extensions.
