Does this mean that the "Legacy" option here will eventually go away, or does this refer to the default? If it is the latter, I don't think we need to mention it here since this documentation is only for the definition of this num - not necessarily its use. There is also a risk of the sentence become out of date. https://github.com/llvm/llvm-project/pull/184730 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
