I'm not super comfortable with this approach because it's a silent behavior change between compiler releases; would it be reasonable to deprecate "fast" entirely (leaving its behavior alone) and introduce two new options: `aggressive` and `user-hostile` (or something perhaps less loaded, lol)? https://github.com/llvm/llvm-project/pull/100453 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
