Hi all,
Recently, I wanted to add a new custom register in gem5, and the load/store
instruction can take the custom register as src/dest register to move data from
memory. Is there some suggestions about this?
And I have some confusion about the register implementation in gem5. In
src/cpu/reg_class.hh/cc file, defining the RegClass and RegId class, if I add a
new custom register, should I add a new Regclass, like CustomClass, and give it
new RegId? And in the src/arch/arm, there are five files about the register:
ccregs.hh??intregs.hh??miscregs.hh/cc ??registers.hh .In these files, everyone
of these file almost enumorate the RegIndex, I understand it just a signature
of a register, how can i map the register to the signature?
Thanks,
ZhangMeng
