The powerpc finite optimization do not show much gain: - 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 patterns, but at cost of others. Comparing against generic C implementation built for powerpc64-linux-gnu-power7 (--with-cpu=power7): - Generic sysdeps/ieee754 implementation: "isfinite": { "": { "duration": 5.0082e+09, "iterations": 2.45299e+09, "max": 43.824, "min": 2.008, "mean": 2.04167 }, "INF": { "duration": 4.66554e+09, "iterations": 2.28288e+09, "max": 35.73, "min": 2.008, "mean": 2.04371 }, "NAN": { "duration": 4.66274e+09, "iterations": 2.28716e+09, "max": 34.161, "min": 2.009, "mean": 2.03866 } } - power7 optimized one: "isfinite": { "": { "duration": 4.99111e+09, "iterations": 2.65566e+09, "max": 25.015, "min": 1.716, "mean": 1.87942 }, "INF": { "duration": 4.6783e+09, "iterations": 2.0999e+09, "max": 35.264, "min": 1.868, "mean": 2.22787 }, "NAN": { "duration": 4.67915e+09, "iterations": 2.08678e+09, "max": 38.099, "min": 1.869, "mean": 2.24228 } } So it basically optimizes marginally for normal numbers while increasing the latency for other kind of FP. - The power8 implementation is just the generic implementation using ISA 2.07 mfvsrd instruction (which GCC uses for generic implementation). So generic implementation is the best option for powerpc64le.
