In that case: - - reg will be the 3rd operand of MUL and it will be of type -MO_MInstrVirtualReg. The field MachineInstr* minstr will point to the -instruction that computes reg. - - numElements will be an immediate constant, not a register. - - %sp will be operand 1 of ADD and it will be of type MO_MachineReg. The -field regNum identifies the register. - - numElements will be operand 2 of ADD and it will be of type -MO_VMVirtualReg. The field Value* value identifies the value. - - ptr will be operand 3 of ADD will also be %sp, i.e., of - type MO_MachineReg. regNum identifies the register. - ---Vikram - |
