3 | All assembler in this directory are just version of the file | ||
4 | crypto/bn/bn_asm.c. | ||
5 | |||
6 | Quite a few of these files are just the assembler output from gcc since on | ||
7 | quite a few machines they are 2 times faster than the system compiler. | ||
8 | |||
9 | For the x86, I have hand written assembler because of the bad job all | ||
10 | compilers seem to do on it. This normally gives a 2 time speed up in the RSA | ||
11 | routines. | ||
12 | |||
13 | For the DEC alpha, I also hand wrote the assembler (except the division which | ||
14 | is just the output from the C compiler pasted on the end of the file). | ||
15 | On the 2 alpha C compilers I had access to, it was not possible to do | ||
16 | 64b x 64b -> 128b calculations (both long and the long long data types | ||
17 | were 64 bits). So the hand assembler gives access to the 128 bit result and | ||
18 | a 2 times speedup :-). | ||
19 | |||
20 | There are 3 versions of assembler for the HP PA-RISC. | ||
21 | |||
22 | pa-risc.s is the origional one which works fine and generated using gcc :-) | ||
23 | |||
24 | pa-risc2W.s and pa-risc2.s are 64 and 32-bit PA-RISC 2.0 implementations | ||
25 | by Chris Ruemmler from HP (with some help from the HP C compiler). | ||
