Subject: glsl: add a few missing int64 constant propagation cases
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9c8f017f77188d9048132a30d31f18b9690cbe04;p=mesa.git

glsl: add a few missing int64 constant propagation cases

Fixes KHR-GL45.shader_ballot_tests.ShaderBallotAvailability, which
causes some silly swizzles to appear, triggering this optimization to
get hit.
