I contemplated to have the different enums defined in a seperate `.def` file with the form of: `ENUM(NAME, VAL, LIT)` so that we will just define them in a single spot instead of here and in `llvm/include/llvm/Frontend/HLSL/HLSLRootSignature.h` (from parser pr). But I felt that having this `.def` include another `.def` file become more confusing than helpful, and having them all in a single file would mean having token logic where it isn't applicable. Would appreciate suggestions here. https://github.com/llvm/llvm-project/pull/122981 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
