Subject: glsl: don't inline intrinsics for mediump
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=93076f60d3a177ff2ec9c4b5662ff0ba69e3d0ec;p=mesa.git

glsl: don't inline intrinsics for mediump

They have an empty fxn body, trying to handle them results in the
intrinsic call being expanded into a no-op.
