Subject: i965/fs: Split all 32->64-bit MOVs on CHV, BXT, GLK
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=cfcfa0b9cd1b1d563a988b1250950057c4612ac9;p=mesa.git

i965/fs: Split all 32->64-bit MOVs on CHV, BXT, GLK

Fixes the following tests on CHV, BXT, and GLK:
    KHR-GL46.shader_ballot_tests.ShaderBallotFunctionBallot
    dEQP-VK.spirv_assembly.instruction.compute.uconvert.uint32_to_int64
