Yes, that's the interesting question. Currently we assume that if `__builtin_constant_p(__begin <= __ptr && __ptr < __end)` is false, `__ptr` can't be within the the range `[__begin, __ptr)`. > Note that of the two use cases you mentioned here, neither works with the > code in this PR. :( That's not great :(. We can of course use new builtins (which is probably a good idea anyway), but I don't know how long you support older libc++ versions usually. I think it should be possible to add support for these cases though, right? We're just doing comparisons or checking whether it's possible to read a variable. https://github.com/llvm/llvm-project/pull/122099 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
