__builtin_constant_p will still return false in this case, contrary to gcc (whose behavior actually depends on the optimization level). I think if we really want to get the exact gcc behavior, we need to mix it with the optimizer and generate some LLVM intrinsics. But what I was interested on with this patch is at least get a closer behavior as GCC in a constexpr context https://reviews.llvm.org/D35190 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
