Summary DFG JIT - Unify GPRReg & RegisterID
Gavin Barraclough
Reported 2011-04-28 14:35:49 PDT
Currently we use a mix of enum values throughout the DFG JIT to represent gpr registers - the RegisterID provided by the MacroAssembler, and the GPRReg enum giving the sequential register set over which the RegisterBank allocates. Unify the two.
