- * 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!
