Since this same hint is used for all HLSL targets not just DXIL, we should name it differently and translate it to a DXIL name late. Something like `llvm.branch` would match the pattern used by loop hints. @nikic, HLSL has hints for backends to indicate when branches should be flattened or preserved. How do you feel about a generic `llvm.branch` metadata? https://github.com/llvm/llvm-project/pull/116331 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
