SPIR-V leaves a register read before any write undefined and Mesa folds undefined values freely. The unconditional patch 0014 guarded against that and was taken out in #701 because the whole picture shook with DLSS on NVIDIA. Patch 0016 brings the zero start back behind a zero_locals job flag, which vk_caps_driver turns on for RADV, ANV and NVK. TOTK_ZERO_LOCALS overrides it, and gfx_shader_set_host mixes it into the translator identity so the variant has its own cache keys. FXAA_FS gains the flag-on hash of the game's FXAA shader, so vk_dlaa_skip_draw knows it on Mesa too. A game run with TOTK_ZERO_LOCALS=1 on an RX 9070 produced that hash; a TOTK_FXAA=0 run logged no skip with either hash, so the switch itself is not confirmed. All 29736 stored 1.4.3 inputs translate with the flag off and on, 0 spirv-val failures. FXAA hashes to 5c43ae18948d52cb with the flag off and aad42238801d31d8 with it on. Flag-on output matches the old translator byte for byte on a sample of 312 shaders. Not run on a Mesa driver. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
