2006-05-12FP programs are back to running... Condition Codes can be read and set...Korey Sewell
Special Regs (Hi,Lo,FCSR) are now added to the operands for use in decoder.isa. Now it's back to just debugging execution of code for the release (those unaligned memory access instruction pairs are still quite the pain i might add) arch/mips/isa_traits.hh: declare functions for .cc file arch/mips/isa_traits.cc: delete unnecessary overloaded functions implement condition code functions implement round function arch/mips/isa/base.isa: remove R31 constant... define in the operands.isa file instead arch/mips/isa/decoder.isa: wholesale changes once again to FP. Now the FP Condition Codes are implemented and the FP programs can run and complete to finish. Use isnan() instead of my unorderedFP() function Also, we now access special regs such as HI,LO,FCSR,etc. just like we do any other reg. operand arch/mips/isa/operands.isa: add more operands for special control regs in int and FP regfiles arch/mips/isa/formats/branch.isa: use R31 instead of r31 arch/mips/isa/formats/fp.isa: use MakeCCVector to set Condition Codes in FCSR arch/mips/regfile/float_regfile.hh: treat control regs like any other reg. Just Index them after the regular architectural registers arch/mips/regfile/int_regfile.hh: treat hi,lo as regular int. regs w/special indexing arch/mips/regfile/regfile.hh: no longer need for special register accesses with their own function. --HG-- rename : arch/mips/regfile.hh => arch/mips/regfile/regfile.hh extra : convert_revision : 5d2f8fdb59606de2b2e9db3e0a085240561e479e

2006-05-11First pass at a serializer object, may need to work on naming of object and ↵Ron Dreslinski
functions: Intended Use: A SimObject will call the serializer when it needs the state to be serializable (i.e. switchCPUs, checkpoint, switch memory access model). It will call the requestSeialization() function. The Serializer will signal all the objects in its list to drain their state via the SimObject method drain(). Drain() has a default implementation to just signal done. When each object is drained it will signal the Serializer that it has drained via the signalDrained() function. The Serializer will collect these signals, when all have drained it will signal the initial requestor via serializationComplete() method in the SimObject. Once that object is done, it will signal the Serializer to resumeExecution(). The Serializer will signal all the objects in its list to resume via the resume() method on the SimObject. SConscript: Add serializer object to build list sim/sim_object.cc: Add default behavior for drain (just signal finished, must be overided if you really must drain something) sim/sim_object.hh: Add functions for serializer --HG-- extra : convert_revision : 15aa2d1b42010c2d703bef9114c11d079c216170

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...

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.
