Clang defines `__FLT_HAS_DENORM__` and friends unconditionally, so I thought we could do this for `FLT_HAS_SUBNORM` as well, considering that gcc did the same. But that might be misleading because gcc's float.h was just for the target of that particular gcc build. Am I right to understand that `__FLT_HAS_DENORM__` signifies *compiler* support for denorms as opposed to support on the *platforms* supported? If so, it might support our alternative consideration of defining these macros in the bionic/libc headers for Android (and rely on the include_next similar to Windows and Darwin). https://reviews.llvm.org/D37302 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
