It is intended to have no side-effects. I followed the same logic used by `__buildin_constant_p`, and the CodeGen tests attempt to validate the lack of side-effects. I didn't see a difference in your godbolt link? Neither incremented `a`. (Though neither built, so perhaps my tweaking changed the result?) https://github.com/llvm/llvm-project/pull/132524 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
