◆ getInstSizeInBytes()
|
override |
GetInstSize - Return the number of bytes of code the specified instruction may be.
This returns the maximum number of bytes.

◆ getRegisterInfo()
|
inline |
getRegisterInfo - TargetInstrInfo is a superset of MRegister info.
As such, whenever a client has an instance of instruction info, it should always be able to get register info as well (through this method).

◆ isLoadFromStackSlot()
|
override |
isLoadFromStackSlot - If the specified machine instruction is a direct load from a stack slot, return the virtual or physical register number of the destination along with the FrameIndex of the loaded stack slot.
If not, return 0. This predicate must return 0 if the instruction has any side effects other than loading from the stack slot.

◆ isStoreToStackSlot()
|
override |
isStoreToStackSlot - If the specified machine instruction is a direct store to a stack slot, return the virtual or physical register number of the source reg along with the FrameIndex of the loaded stack slot.
If not, return 0. This predicate must return 0 if the instruction has any side effects other than storing to the stack slot.
