From: Rhys Perry Date: Fri, 17 Jul 2020 10:46:47 +0000 (+0100) Subject: spirv: don't split memory barriers X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fac813dc61e7298dfe9ee28295843a30eb253296;p=mesa.git spirv: don't split memory barriers If the SPIR-V had a shared+image memory barrier, we would emit two NIR barriers: a shared barrier and an image barrier. Unlike a single barrier, two barriers allows transformations such as: intrinsic image_deref_store (ssa_27, ssa_33, ssa_34, ssa_32, ssa_25) (1) intrinsic memory_barrier_shared () () intrinsic memory_barrier_image () () intrinsic store_shared (ssa_35, ssa_24) (0, 1, 4, 0) -> intrinsic memory_barrier_shared () () intrinsic store_shared (ssa_35, ssa_24) (0, 1, 4, 0) intrinsic image_deref_store (ssa_27, ssa_33, ssa_34, ssa_32, ssa_25) (1) intrinsic memory_barrier_image () () This commit fixes two dEQP-VK.memory_model.* CTS tests with ACO.
