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! 42 * 43 * <appro (at) fy.chalmers.se> 44 */ 45 #include <asm.h> 46 #include <regdef.h> 47 48 #if _MIPS_ISA>=4 49 #define
