smeenai added a comment. @bcraig: `__STDC_NO_ATOMICS__` wouldn't be defined for pre-C11 compilers either, right?
From what I understand of the original code sample, one of the purposes was to check for 64-bit atomic support on 32-bit systems (hence the use of `uintmax_t` and the check for `__atomic_fetch_add_8`). I don't really know of a portable way of accomplishing that without at least including `<stdint.h>`. https://reviews.llvm.org/D23719 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
