/*
|
|
* 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!
