The pattern of calling opt algebraic first seems to have originated in i965. The order in OpenGL drivers generally doesn't matter because the GLSL IR optimisations do constant folding before opt algebraic. However in Vulkan drivers calling opt algebraic first can result in missed constant folding opportunities. vkpipeline-db results (VEGA64): Totals from affected shaders: SGPRS: 3160 -> 3176 (0.51 %) VGPRS: 3588 -> 3580 (-0.22 %) Spilled SGPRs: 52 -> 44 (-15.38 %) Spilled VGPRs: 0 -> 0 (0.00 %) Private memory VGPRs: 0 -> 0 (0.00 %) Scratch size: 12 -> 12 (0.00 %) dwords per thread Code Size: 261812 -> 261036 (-0.30 %) bytes LDS: 7 -> 7 (0.00 %) blocks Max Waves: 346 -> 348 (0.58 %) Wait states: 0 -> 0 (0.00 %) Reviewed-by: Samuel Pitoiset <samuel.pitoiset@gmail.com> Reviewed-by: Bas Nieuwenhuizen <bas@basnieuwenhuizen.nl> |
