* Move bigint_simple_mul into mp_mul.cpp, since that is the only place itlloyd2006-08-194-17/+26

* Move Montgomery reduction algorithm into mp_asm.cpplloyd2006-08-198-110/+69
| | | | | | | | | | Move the inner-most loop of Montgomery into bigint_mul_add_words, in mp_muladd.cpp Use bigint_mul_add_words for the inner loop of bigint_simple_multiply Move the compare/subtract at the end of the Montomgery algorithm into bigint_monty_redc
* Don't test Skipjack at startup - it's really not that important, andlloyd2006-08-191-8/+0
| | | | | running the test means the algorithm prototype is loaded into memory when it will probably never be used later.

* Inline the call to word_add in bigint_monty_redc - the carry in waslloyd2006-08-171-3/+3
| | | | | | always zero, so this is both a bit more efficient and more readable. It won't be able to take advantage of asm implementations of word_add, but the benefit from that with a single call per loop is small anyway.
* Move bigint_monty_redc to its own file; profiling indicates that thislloyd2006-08-172-33/+49

* Split Montgomery reduction into two functions, the core algorithm linkedlloyd2006-08-163-6/+15
| | | | | | as C (for replacing by asm later), and another that performs a subtract if needed (inside powm_mnt.cpp). That way an asm version of the Montgomery algorithm won't have to deal with calling other functions.
