Joseph Myers c0c49d60cf Simplify NAN definitions. ... Similar to my patches for HUGE_VAL and INFINITY. this patch eliminates the bits/nan.h headers. __builtin_nanf ("") is used to define NAN for GCC 3.3 and later; the fallback is (0.0f / 0.0f), which is a constant expression for a quiet NaN of type float, but raises a spurious "invalid" exception outside static initializers, which seems the best that can be done purely in standard C. Again, if anyone actually uses a compiler with its own incompatible extension for producing a constant quiet NaN, we can add compiler conditionals. Tested for x86_64. * math/math.h [__USE_ISOC99] (NAN): Define directly here. Do not include <bits/nan.h>. * math/Makefile (headers): Remove bits/nan.h. * bits/nan.h: Remove. * sysdeps/ieee754/bits/nan.h: Likewise. * sysdeps/mips/bits/nan.h: Likewise.		2017-08-31 16:39:25 +00:00
