spirv*-mesa-mesa3d are legal clang targets since 3c6fe49a912a. spirv-diff shows only numbering change to spirv64-mesa-mesa3d/libclc.spv. llvm-diff shows no change on reverse-translated bitcode files. Also fixes a bug that spirv32-mesa-mesa3d was incorrectly using 64-bit triple spir64--. Update README.md to use spirv32-mesa-mesa3d instead of logical SPIR-V. >From d7d490ce095e330a7660e1288e85572b810c4d43 Mon Sep 17 00:00:00 2001 From: Wenju He <[email protected]> Date: Tue, 26 May 2026 08:22:09 +0200 Subject: [PATCH] [libclc] Use native spirv*-mesa-mesa3d clang triple for mesa spirv*-mesa-mesa3d are legal clang targets since 3c6fe49a912a. spirv-diff shows only numbering change to spirv64-mesa-mesa3d/libclc.spv. llvm-diff shows no change on reverse-translated bitcode files.
