Understood, there is likely value to a 'FIXME' that has some sort of sub-locations/expansion locations suggested as a point of something we should fix in the future. BUT, the current 'this is an array of locations' likely doesn't comprehend that well. Currently when clang does diagnostics on a macro expansion, we do a bunch of notes of "in expansion of macro...", which includes the name and location of the macro being expanded. It seems that `FusedLoc` would need some way of referring to a separate entity to get this, so I don't see it being useful for this. Again though, a `FIXME: at one point we should capture macro expansions here so we can diagnose expansions more thoroughly` is perhaps not a bad addition here. https://github.com/llvm/llvm-project/pull/113483 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
