[PATCH] D148637: [LangRef] Update shufflevector's semantics to return poison if the mask is undef

Tue Apr 25 15:38:06 PDT 2023

ManuelJBrito added inline comments.

================
Comment at: llvm/docs/LangRef.rst:10097
+LLVM's assembly printer will print ``poison`` if ``undef`` was given to the
+shuffle mask because LLVM does not distinguish between them internally.
