      3 All assember 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 assember output from gcc since on 
      7 quite a few machines they are 2 times faster than the system compiler.

      9 For the x86, I have hand written assember 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 assember (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 assember gives access to the 128 bit result and
     18 a 2 times speedup :-).

     20 There are 3 versions of assember 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).
