I though I'd resubmit a PA-RISC 2.0 bn_asm patch I submitted back in
April that doesn't seem to have generated any discussion:
A patch containing:
o an attempt at arriving closer to a set of unified HP-UX targets
o new PA-RISC 2.0 implementations of the bn_asm code (32 and 64-bit)
by Chris Ruemmler from HP
is at http://people.hp.se/stevesk/patch/parisc2.patch
Here are comparisons of the RSA and DSS numbers for both 32 and 64 bit
builds. If I recall these are from a 440Mhz N-class system.
