URL: https://github.com/llvm/llvm-project/commit/38045dd89590f88c6724ff838ded6b9a6e56e713 DIFF: https://github.com/llvm/llvm-project/commit/38045dd89590f88c6724ff838ded6b9a6e56e713.diff LOG: [CIR][X86][NFC] Add _mm_alignr_epi8 edge immediate tests (#198522) Cover the 16-byte boundary and all-zero result cases in `ssse3-builtins.c`. These cases mirror the coverage in `clang/test/CodeGen/palignr.c`. Rename the existing `_mm_alignr_epi8` cases consistently with the new tests. Partially addresses https://github.com/llvm/llvm-project/issues/156747.
