`TargetLowering` is implemented in the backend, but is also optional. If not provided, the max size of atomic operations is assumed to be 16. I think that frontends having to resolve the ABI information independently would be worse. https://github.com/llvm/llvm-project/pull/101966 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
