This patch relaxes copy-propagation for PSEUDO instructions with subdword Operands / Definitions: general: - only propagate VGPR temps if the Definition is VGPR (or on p_as_uniform) parallelcopy/create_vector/phis: - size has to be the same extract_vector/split_vector: - propagate SGPR temps on GFX9+ or if the Definitions are not subdword - split_vector: size must not increase Totals from 282 (0.20% of 140985) affected shaders (Polaris10): VGPRs: 14520 -> 14408 (-0.77%) CodeSize: 2693956 -> 2694316 (+0.01%); split: -0.20%, +0.21% Instrs: 512874 -> 512864 (-0.00%); split: -0.16%, +0.16% Cycles: 26338860 -> 26320652 (-0.07%); split: -0.36%, +0.29% VMEM: 49460 -> 49634 (+0.35%); split: +0.47%, -0.12% SMEM: 10035 -> 10036 (+0.01%) VClause: 7675 -> 7674 (-0.01%) Copies: 66012 -> 65943 (-0.10%); split: -1.31%, +1.20% Branches: 17265 -> 17281 (+0.09%); split: -0.10%, +0.19% PreVGPRs: 12211 -> 12124 (-0.71%) Reviewed-by: Rhys Perry <pendingchaos02@gmail.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/8260>
