That is a problem worth fixing but it's not unique to this change unfortunately. Examples like this succeed: ``` $ ./bin/clang -march=armv8.1-a+sve2 /tmp/test.c ``` Which is a larger issue with clang. At least with this change, `-mcpu=neoverse-n2+sve+sve2` follows the architecture rules where previously it did not. So that's a good improvement. https://github.com/llvm/llvm-project/pull/75055 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
