This usage pattern is usually not performance oriented and for such calls PLT overhead should dominate execution time. - The power5, power6, and power6x are just micro-optimization to improve the Load-Hit-Store hazards from floating-point to general register transfer, and current GCC already has support to minimize it by inserting either extra nops or group dispatch instructions. - The power7 uses ftdiv to optimize for some input patterns, but at cost of others. Comparing against generic C implementation built for powerpc-linux-gnu-power4 (which uses the hp-timing support on benchtests): - Generic sysdeps/ieee754 implementation: "isnan": { "": { "duration": 4.98415e+09, "iterations": 2.34516e+09, "max": 45.925, "min": 2.052, "mean": 2.12529 }, "INF": { "duration": 4.74057e+09, "iterations": 1.69761e+09, "max": 91.01, "min": 2.052, "mean": 2.79249 }, "NAN": { "duration": 4.74071e+09, "iterations": 1.68768e+09, "max": 282.343, "min": 2.052, "mean": 2.809 } } - power7 optimized one: $ ./testrun.sh benchtests/bench-isnan "isnan": { "": { "duration": 4.96842e+09, "iterations": 2.56297e+09, "max": 50.048, "min": 1.872, "mean": 1.93854 }, "INF": { "duration": 4.76648e+09, "iterations": 1.54213e+09, "max": 373.408, "min": 2.661, "mean": 3.09084 }, "NAN": { "duration": 4.76845e+09, "iterations": 1.54515e+09, "max": 51.016, "min": 2.736, "mean": 3.08607 } } So it basically optimizes marginally for normal numbers while increasing the latency for other kind of FP. - The generic implementation requires getting the floating point status, disable the invalid operation bit, and restore the floating-point status. Each operation is costly and requires flushing the FP pipeline. Using the same scenarion for the previous analysis: "isnan": { "": { "duration": 5.08284e+09, "iterations": 6.2898e+08, "max": 41.844, "min": 8.057, "mean": 8.08108 }, "INF": { "duration": 4.97904e+09, "iterations": 6.16176e+08, "max": 39.661, "min": 8.057, "mean": 8.08055 }, "NAN": { "duration": 4.98695e+09, "iterations": 5.95866e+08, "max": 29.728, "min": 8.345, "mean": 8.36925 } } - The power8 implementation is just the generic implementation using ISA 2.07 mfvsrd instruction (which GCC uses for generic implementation). So generic implementation already generates best code for powerpc64le.
