Since Or1ksim translates these operations into host FP, there is* little point in testing more of the subtleties of IEEE 745.** However in future this test could be used with OpenRISC hardware, in which* case exhaustive testing would be essential.* ------------------------------------------------------------------------- */#include "spr-defs.h"#include "board.h"#define HAVE_LF_CUST 0#define HAVE_LF_REM 0#define HAVE_LF_MADD 0/** l.nop constants**/#define NOP_NOP 0x0000 /* Normal nop instruction */#define NOP_EXIT 0x0001 /* End of simulation */#define NOP_REPORT 0x0002 /* Simple report */#define NOP_PRINTF 0x0003 /* Simprintf instruction */#define NOP_PUTC 0x0004 /* Simulation putc instruction */#define NOP_REPORT_FIRST 0x0400 /* Report with number */#define NOP_REPORT_LAST 0x03ff /* Report with number *//* ----------------------------------------------------------------------------* Coding conventions** A simple rising stack is provided to starting at _stack and pointed to by* r1. r1 points to the next free word.
