I'm not sure I follow; if you know the object's type, doesn't that mean you also know its size? >(I don't readily know of any transformation that changes a structure's layout. >Does it exist?) Any such transform has to reason about all the uses, so the llvm.objectsize call itself would prevent the transform from happening. https://github.com/llvm/llvm-project/pull/78526 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
