-/* This function uses the same code as s_isinf.S. */
The powerpc isinf optimizations onyl adds complexity: - GCC will call libm iff -fsignaling-nans is used. This usage pattern is usually not performance oriented and for such calls PLT overhead should dominate execution time. - The power7 uses ftdiv to optimize for some input pattern and branch implementation for INF and denormal that does: return (ix & UINT64_C (0x7fffffffffffffff)) == UINT64_C (0x7ff0000000000000) Although it does show slight better latency than generic algorithm, it is only for power7 and requires it to override it for power8. - The power8 implementation is just the generic implementation using ISA 2.07 mfvsrd instruction (which GCC uses for generic implementation). So generic implementation is already the best option for powerpc64le.
