Thanks for the fix. I left a minor suggestion. Some notes: - This commit make Clang emit `error: size of register '???' does not match variable size` error instead of `fatal error: error in backend: Invalid register name "???"`, regardless of the `-ffixed-???` option. - #76426 says "When `-ffixed-x15` is specified, it can be compiled.". When `-ffixed-x15` is specified, older revisions (including 18.1.x releases) compiles the program in #76426 without an error but the generated code is incorrect (the `foo` function is compiled into `mrs w0, NZCV; ret`!). Recent revisions emits `fatal error: error in backend: Invalid register name "x15".`. So make it a Clang error is appropriate. - GCC allows this variable-register size mismatch. Clang does not allow. - We don't need to use `starts_with_insensitive`. Register names are case-sensitive (same as GCC). https://github.com/llvm/llvm-project/pull/94271 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
