◆ EmitDbgInstrRef()

MachineInstr * InstrEmitter::EmitDbgInstrRef	(	SDDbgValue *	SD,

Emit a dbg_value as a DBG_INSTR_REF.

May produce DBG_VALUE $noreg instead if there is no variable location; alternately a half-formed DBG_INSTR_REF that refers to a virtual register and is corrected later in isel.
