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.

arch/mips/isa/formats/branch.isa:
Fix disassembly
arch/mips/isa/formats/int.isa:
Add sign extend Immediate and zero extend Immediate to Int class.
Probably a bit unnecessary in the long run since these manipulations could
be done in the actually instruction instead of keep a int value
arch/mips/isa/formats/mem.isa:
Comment/Remove out split-memory access code... revisit this after SimpleCPU works
arch/mips/isa/formats/unimp.isa:

binary to help in debuggin

arch/mips/linux_process.cc:
assign some syscalls to the right functions
cpu/static_inst.hh:
more debug functions for MIPS (these will be move to the mips directory soon)
mem/page_table.cc:
mem/page_table.hh:
toward a better implementation for unaligned memory access
mem/request.hh:
NO ALIGN FAULT flag added to support unaligned memory access
sim/syscall_emul.cc:
