| /* |
| * This is my modest contributon to the OpenSSL project (see |
| * http://www.openssl.org/ for more information about it) and is |
| * a drop-in MIPS III/IV ISA replacement for crypto/bn/bn_asm.c |
| * module. For updates see http://fy.chalmers.se/~appro/hpe/. |
| * |
| * The module is designed to work with either of the "new" MIPS ABI(5), |
| * namely N32 or N64, offered by IRIX 6.x. It's not ment to work under |
| * IRIX 5.x not only because it doesn't support new ABIs but also |
| * because 5.x kernels put R4x00 CPU into 32-bit mode and all those |
| * 64-bit instructions (daddu, dmultu, etc.) found below gonna only |
| * cause illegal instruction exception:-( |
| * |
| * In addition the code depends on preprocessor flags set up by MIPSpro |
| * compiler driver (either as or cc) and therefore (probably?) can't be |
| * compiled by the GNU assembler. GNU C driver manages fine though... |
| * I mean as long as -mmips-as is specified or is the default option, |
| * because then it simply invokes /usr/bin/as which in turn takes |
| * perfect care of the preprocessor definitions. Another neat feature |
| * offered by the MIPSpro assembler is an optimization pass. This gave |
| * me the opportunity to have the code looking more regular as all those |
| * architecture dependent instruction rescheduling details were left to |
| * the assembler. Cool, huh? |
| * |
| * Performance improvement is astonishing! 'apps/openssl speed rsa dsa' |
| * goes way over 3 times faster! |
