URL: https://github.com/llvm/llvm-project/commit/6a7b8876153815cf3847d952614440e79e82fc86 DIFF: https://github.com/llvm/llvm-project/commit/6a7b8876153815cf3847d952614440e79e82fc86.diff LOG: [libclc] Use generic spirv*-unknown-unknown clang triple for SPIR-V targets (#199618) spirv-diff shows only numbering change to spirv64-unknown-unknown/libclc.spv. No change in `llvm-spirv -to-text` outputs. llvm-diff shows no change on reverse-translated bitcode files. Also fixes a bug that spirv32-unknown-unknown was incorrectly using 64-bit triple. Update README.md to use the generic target triple for SPIR-V targets.
