1All assember in this directory are just version of the file
2crypto/bn/bn_asm.c.

4Quite a few of these files are just the assember output from gcc since on 
5quite a few machines they are 2 times faster than the system compiler.

7For the x86, I have hand written assember because of the bad job all
8compilers seem to do on it.  This normally gives a 2 time speed up in the RSA
9routines.
10
11For the DEC alpha, I also hand wrote the assember (except the division which
12is just the output from the C compiler pasted on the end of the file).
13On the 2 alpha C compilers I had access to, it was not possible to do
1464b x 64b -> 128b calculations (both long and the long long data types
15were 64 bits).  So the hand assember gives access to the 128 bit result and
16a 2 times speedup :-).
17
18There are 2 versions of assember for the HP PA-RISC.
19pa-risc.s is the origional one which works fine.
20pa-risc2.s is a new version that often generates warnings but if the
21tests pass, it gives performance that is over 2 times faster than
22pa-risc.s.
23Both were generated using gcc :-)
