It probably makes more sense to add a routine to compiler-rt that returns the value of VG if SVE is available, rather than emitting an error here. You can implement that function using the (already existing) interfaces for function-multiversioning to check if SVE is available at runtime. In that case, I think there is little value in having these Clang changes here. @efriedma-quic are you happy going with that approach instead? https://github.com/llvm/llvm-project/pull/83301 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
