Hi All,
I am working on log10/qsort benchmarks on ARM64 (ARMv8) processor,
I want to check if we have experience with these benchmarks.
Actually i am looking for a compiler version which gives best results with
these benchmarks and specific compiler optimization (in my case is see O3
gives best numbers) ?
I have tried GCC-4.9 and GCC-6.2 with log10 benchmark and my observations
are:
1) With gcc 4.9 - 140 us
2) With GCC 6.2 - 150 us
My compilation flags are "-O3 -ftree-vectorize -funroll-all-loops --param
max-inline-insns-auto=550 --param case-values-threshold=30
-falign-functions=32 -ftracer"
So it seems like gcc-6.2 is better, am i missing something, should i use
some better compiler flags?
Thanks
-Bharat
