-/* The original fdlibm code used statements like:
- n0 = ((*(int*)&one)>>29)^1; * index of high word *
- ix0 = *(n0+(int*)&x); * high word of x *
- ix1 = *((1-n0)+(int*)&x); * low word of x *
- to dig two 32 bit words out of the 64 bit IEEE floating point
- value. That is non-ANSI, and, moreover, the gcc instruction
- scheduler gets it wrong. We instead use the following macros.
- Unlike the original code, we determine the endianness at compile
- time, not at run time; I don't see much benefit to selecting
- endianness at run time. */
