Subject: RE: machine instruction operands
|
|
|
|
I got interrupted and forgot to explain the example. 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.
