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! - * - * <appro@fy.chalmers.se> - */ -#include <asm.h> -#include <regdef.h> - -#if _MIPS_ISA>=4 -#define MOVNZ(cond,dst,src) \ - movn dst,src,cond -#else -#define MOVNZ(cond,dst,src) \ -
