1All assember in this directory are just version of the file 2crypto/bn/bn_asm.c. 3 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. 6 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 :-) 24
