This case can be handled with a named list in tablegen and a `listconcat` without exposing it as a subtarget feature. > When disassembling some object files, we don't need a long -mattr if we know > it's compiled with a profile. If objdump requires you to use `-mattr`, instead of `-march`, that's a bad interface design. Users of objdump shouldn't need to know if they to have pass `experimental-` before an extension name. > When doing some end-to-end tests that we need to discard CPU specific > features (so we can't use -mcpu), we don't need a long -mattr. This might be an argument for a `generic-<profile>` `mcpu`. https://github.com/llvm/llvm-project/pull/76357 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
