Sorry, I only saw this now. I second @efriedma-quic 's feedback that a RFC seems appropriate. An aspect that I hope the RFC could cover is whether this could be initially implemented LLVM-side only (e.g. via some manifest file saying which functions should be treated this way) - effectively a gradual introduction. https://github.com/llvm/llvm-project/pull/165777 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
