URL: https://github.com/llvm/llvm-project/commit/630f82ec0c61b772711355fad08ed0d0adce922d DIFF: https://github.com/llvm/llvm-project/commit/630f82ec0c61b772711355fad08ed0d0adce922d.diff LOG: [Clang][CodeGen] Loose the cast check when emitting builtins (#81669) This patch looses the cast check (`canLosslesslyBitCastTo`) and leaves it to the one inside `CreateBitCast`. It seems too conservative for the use case here.
