2006-05-07Minor changes for FP ... MIPS now works for floating-point programs...Korey Sewell
Now we are to the point where more benchmarks and instruction-coverage is necessary to totally verify/validate correct operation across all MIPS instructions arch/mips/isa_traits.hh: fix for reading double values ... must rearrange bits before using void* to read double. configs/test/hello_mips: real hello world MIPS binary --HG-- extra : convert_revision : 153de1f8a830882c6972bd0bdb56da818f614def

Once I switched this the basic MIPS FP test I had worked. --HG-- extra : convert_revision : 45c80df229e6174d0b52fc7cfb530642b1f1fc35

This probably needs to be fixed up so there are immediate and register versions. arch/sparc/isa/operands.isa: Added an R1 operand, and fixed up the numbering arch/sparc/isa_traits.hh: SyscallNumReg is no longer needed, the max number of sources and destinations are fixed up, and the syscall return uses xcc instead of icc. arch/sparc/linux/process.cc: arch/sparc/linux/process.hh: Added a getresuidFunc syscall implementation. This isn't actually used, but I thought it was and will leave it in. arch/sparc/process.cc: arch/sparc/process.hh: Fixed up how the initial stack frame is set up. arch/sparc/regfile.hh: Changed the number of windows from 6 to 32 so we don't have to worry about spill and fill traps for now, and commented out the register file setting itself up. cpu/cpu_exec_context.hh: cpu/exec_context.hh: cpu/simple/cpu.hh: sim/process.cc: sim/process.hh: Changed the syscall mechanism to pass down the syscall number directly. --HG-- extra : convert_revision : 15723b949a0ddb3d24e68c079343b4dba2439f43

2006-04-14These fixes now allow all of the 20 mips tests to work properly!Korey Sewell
Floating Point Mips Tests still need to be added, tested, and debugged. arch/mips/isa/decoder.isa: Fix mult and multu instructions. This semantic error causes the problem: <int64> = <int32> * <int32>. Although I was placing the output into a 64-bit integer the multiply was just doing a 32-bit multiply so the solution is to just use the 'sd' & 'ud' operands so that the ISA parser will use the int64_t and uint64_t types in calculation. arch/mips/isa/formats/int.isa: Trace output fix.
