Hi
I applied that patch, turned on fastmint in the Makefile and put it
in:
http://www.hashcash.org/source/current/hashcash-1.03/hashcash-1.03pr1.tgz
I notice the fastest version on P4 seems to have decided it doesn't
work on this hardware:
Rate Name (* machine default)
1536929 ANSI Compact 1-pipe *
1553107 ANSI Standard 1-pipe
1229543 ANSI Ultra-Compact 1-pipe
1229543 ANSI Compact 2-pipe
1569629 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)
Also I get errors like this if you try to mint:
./hashcash -mb10 foo
time estimate: 0 seconds (632 micro-seconds)
ERROR: requested 10 bits, reported 10 bits, got 0 bits using ANSI Standard
1-pipe minter: "1:10:040812:foo::9kwf9ZjG3cSKN+63:000000Ll"
