================ Comment at: clang/utils/TableGen/SveEmitter.cpp:1477 + + OS << "#if !defined(__ARM_FEATURE_SME)\n"; + OS << "#error \"SME support not enabled\"\n"; ---------------- We have been changing how the existing SVE and NEON instrinsics work a little. There are some details in https://reviews.llvm.org/D131064. The short version is it is best to not rely upon preprocessor macros, and instead define the intrinsics so that they can be used if the right target features are available. This allows us to do things like this below, even without a -march that supports sme, and have them callable at runtime under the right situations. We should be doing the same for SME. ``` __attribute__((target("+sme"))) void sme_func() { somesmeintrinsics(); } ``` Repository: rG LLVM Github Monorepo CHANGES SINCE LAST ACTION https://reviews.llvm.org/D127910/new/ https://reviews.llvm.org/D127910 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
