I understand quickpar has asm for the critical code
paths. par2cmdline is portable and doesn't include any
asm.
How difficult would it be to add the asm as a config
option so full speed on those platforms can be
realized? It seems a waste that asm already written
can't be used when possible.
Other projects such as loop-aes and mplayer can be
configured and built with portable C if asm isn't
available for the build platform.
