| 16 /* | |
| 17 * This is my modest contributon to the OpenSSL project (see | |
| 18 * http://www.openssl.org/ for more information about it) and is | |
| 19 * a drop-in MIPS III/IV ISA replacement for crypto/bn/bn_asm.c | |
| 20 * module. For updates see http://fy.chalmers.se/~appro/hpe/. | |
| 21 * | |
| 22 * The module is designed to work with either of the "new" MIPS ABI(5), | |
| 23 * namely N32 or N64, offered by IRIX 6.x. It's not ment to work under | |
| 24 * IRIX 5.x not only because it doesn't support new ABIs but also | |
| 25 * because 5.x kernels put R4x00 CPU into 32-bit mode and all those | |
| 26 * 64-bit instructions (daddu, dmultu, etc.) found below gonna only | |
| 27 * cause illegal instruction exception:-( | |
| 28 * | |
| 29 * In addition the code depends on preprocessor flags set up by MIPSpro | |
| 30 * compiler driver (either as or cc) and therefore (probably?) can't be | |
| 31 * compiled by the GNU assembler. GNU C driver manages fine though... | |
| 32 * I mean as long as -mmips-as is specified or is the default option, | |
| 33 * because then it simply invokes /usr/bin/as which in turn takes | |
| 34 * perfect care of the preprocessor definitions. Another neat feature | |
| 35 * offered by the MIPSpro assembler is an optimization pass. This gave | |
| 36 * me the opportunity to have the code looking more regular as all those | |
| 37 * architecture dependent instruction rescheduling details were left to | |
| 38 * the assembler. Cool, huh? | |
| 39 * | |
| 40 * Performance improvement is astonishing! 'apps/openssl speed rsa dsa' | |
| 41 * goes way over 3 times faster! | |
