Quite a few of these files are just the assember output from gcc since on quite a few machines they are 2 times faster than the system compiler.For the x86, I have hand written assember because of the bad job allcompilers seem to do on it. This normally gives a 2 time speed up in the RSAroutines.For the DEC alpha, I also hand wrote the assember (except the division whichis just the output from the C compiler pasted on the end of the file).On the 2 alpha C compilers I had access to, it was not possible to do64b x 64b -> 128b calculations (both long and the long long data typeswere 64 bits). So the hand assember gives access to the 128 bit result anda 2 times speedup :-).
There are 3 versions of assember for the HP PA-RISC.pa-risc.s is the origional one which works fine and generated using gcc :-)pa-risc2W.s and pa-risc2.s are 64 and 32-bit PA-RISC 2.0 implementationsby Chris Ruemmler from HP (with some help from the HP C compiler).
