I assume you're talking about VMS, or is there another architecture
involved as well? Would you mind telling me the VMS version and C
compiler version? Is it on VAX? Can you tell me a little more about
the problem? See, I assume you work on Alpha or ia64, otherwise
pqueue would use BIGNUM for PQ_64BIT (because VAX doesn't have 'long
long' according to our configuration parameters), so I've a hard time
understanding the argument about 32-bit registers.
It's not VMS, it's AmigaOS. Some compilers don't have 64-bit variable support
so I thought VMS changes would be useful. The shared library model is
compiler independent, but passing of larger than 32-bit arguments in shared
libraries is not supported on some compilers.
This can be worked around, but I think it would make more sense to have
pitem_new and pqueue_find take pointers to PQ_64BIT arguments, ie. I think it
would be better to have BIGNUM * passed than the whole BIGNUM structure.
For systems using 64-bit BN_U[L]LONG for PQ_64BIT, there should be no
performance penalty (or a very minimal one, but this doesn't seem to be
a performance critical component).
