2006-05-11Fixes for Paired-Single FP Compare Operations...Korey Sewell
Now all the variations of FP should be implemented correctly in the decoder. The new formats and functions supporting these functions need to be implemented for some of the FP stuff but for the most part things are looking like their "supposed to"... arch/mips/isa/decoder.isa: Fixes for Paired-Single FP Compare Operations...

2006-05-10Support for FP Paired Single OperationsKorey Sewell
Auxiliary Functions and Formats for FP in general arch/mips/isa/decoder.isa: ISA Parser doesnt accept operands of different types in one instruction so fix this for unorderedFP functions... Add basic support for Paired Singled (PS) FP ops which happen to be part of the MIPS 32-ASE but turned out to be included in the MIPS32ISA manual... The PS instructions allow SIMD in a pipeline... arch/mips/isa/formats/fp.isa: Add some more Formats for FP operation. I will add some auxiliary code through these formats to alleviate code redundancy in the decoder.isa arch/mips/isa/operands.isa: Add operands for Paired Singles Ops arch/mips/isa_traits.cc: removed convert&round function and replace with fpConvert. The whole "rounding mode" stuff is something that should be considered for full-system mode...

2006-05-10revamping code to appropriately handle FP condition code and conversion ops.Korey Sewell
There still needs to be a work around to handle the paired singles operations ... arch/mips/isa/decoder.isa: More revamping of the floating point ops in decoder.isa. Change all of the "convert and round" functions to fpConvert. Also, the utility functions roundFP, truncFP, and unorderedFP are in place everywhere. Things have been set up to appropriately use the FP condition codes in the decoder.isa The fp.isa format file and the isa_traits.cc file now needed to be updated to implement the appropriate "backend" operations/functionality... arch/mips/isa_traits.hh: Remove convert & round functions Add roundFP, truncFP,unorderedFP, and the get/setFPconditionCode functions arch/mips/isa_traits.cc: Add utility functions --HG-- extra : convert_revision : 3d6708388abae5b432467f528d52e6343afecd9c

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.

2006-04-07Move to a model with a unified request object.Ron Dreslinski
Constructor takes a bool to signify that it is either a cpu_request or not a cpu_request. When accedding variables of a cpu_request it asserts that it is a cpu_request. It also asserts that a value being read has been written at some point in time prior (not gaurnteeing it is up to date, but it was at least written before read). There is also a isCpuReq() function to determine if this is a cpu_request. It should be called before accesing a cpu_request only variable. SConscript: Add compilation support for request.cc arch/alpha/tlb.cc: arch/alpha/tlb.hh: cpu/cpu_exec_context.hh: cpu/exec_context.hh: cpu/simple/cpu.cc: cpu/simple/cpu.hh: dev/io_device.cc: mem/page_table.cc: mem/page_table.hh: mem/port.cc: Update for unified request object and accessor functions. mem/request.hh: Remove CpuRequest, make it a unified object. Make variables private with accessor functions. May want to move things from .cc file into header (usually a assert() and either returning a value, or writting two). --HG-- extra : convert_revision : f1e45cc490dadc7a418634539b03c3e72684a6e3
