◆ isLoadFromStackSlot()

Stack Spill & Reload {.

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.
