Duncan P. N. Exon Smith 42f8eee150 cmath: Skip Libc for integral types in isinf, etc. ... For std::isinf, the standard requires effectively calling isinf as double from Libc for integral types. But integral types are never infinite; we don't need to call Libc to return false. Also short-circuit other functions where Libc won't have interesting answers: signbit, fpclassify, isfinite, isnan, and isnormal. I added correctness tests for integral types since we're no longer deferring to Libc. In review it was pointed out that in future revisions of the C++ standard we may add more types to std::is_arithmetic (e.g., std::is_fixed_point). I'll leave it to a future commit to hack this to allow using math functions on those. We'll need to change things like __libcpp_fpclassify anyway, so I'm not sure anything here would really be future-proof. https://reviews.llvm.org/D31561 rdar://problem/31361223 llvm-svn: 301060		2017-04-21 23:14:55 +00:00
