OK, I remembered I had an account on a newer alpha machine (EV6,
666MHz), which has gcc 3.2.
using just -O3 -funroll-loops:
739957 ANSI Compact 1-pipe
984842 ANSI Standard 1-pipe *
166508 ANSI Ultra-Compact 1-pipe
842660 ANSI Compact 2-pipe
820702 ANSI Standard 2-pipe
--- PowerPC Altivec Standard 1x4-pipe (Not available on this machine)
--- PowerPC Altivec Compact 2x4-pipe (Not available on this machine)
--- PowerPC Altivec Standard 2x4-pipe (Not available on this machine)
--- AMD64/x86 MMX Compact 1x2-pipe (Not available on this machine)
--- AMD64/x86 MMX Standard 1x2-pipe (Not available on this machine)
Best minter: ANSI Standard 1-pipe (984842 hashes/sec)
using -O3 -funroll-loops -mcpu=ev6 -mtune=ev6:
737431 ANSI Compact 1-pipe
934900 ANSI Standard 1-pipe *
169419 ANSI Ultra-Compact 1-pipe
889778 ANSI Compact 2-pipe
800706 ANSI Standard 2-pipe
--- PowerPC Altivec Standard 1x4-pipe (Not available on this machine)
--- PowerPC Altivec Compact 2x4-pipe (Not available on this machine)
--- PowerPC Altivec Standard 2x4-pipe (Not available on this machine)
--- AMD64/x86 MMX Compact 1x2-pipe (Not available on this machine)
--- AMD64/x86 MMX Standard 1x2-pipe (Not available on this machine)
Best minter: ANSI Standard 1-pipe (934900 hashes/sec)
So there doesn't seem to be much difference between optimization the
flags. At least now the default is the fastest.
