Instead of relying on asserting the array length to be multiples of 3, maybe be we could encode the `(C-name, asm-name, location)` triplets as a proper type to be reused with `WeakUndeclaredIdentifiers`. This does not have to be done in this patch now. https://github.com/llvm/llvm-project/pull/186755 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
