Hi Nilay,
I cannot build gem5 after applying this patch.
My command is: scons RUBY=true build/X86/gem5.fast
The output (it is just the beginning of the build):
In file included from /home/matara/gem5/build/X86/arch/x86/isa/main.isa:

scons: *** [build/X86/arch/x86/generated/max_inst_regs.hh] Explicit exit, status /home/matara/gem5/build/X86/arch/x86/isa/decoder/x87.isa:86: error defining "FLD1": Unrecognized instruction: FLD1.
scons: building terminated because of errors.
/home/matara/gem5/build/X86/arch/x86/isa/decoder/x87.isa:86: error defining "FLD1": Unrecognized instruction: FLD1.
I do not know if this is because of my installation or a bug.
