; Make sure we use the correct frame offset is used with the local
; frame area.
;
; %pin.low is allocated to offset 0.
;
; %local.area is assigned to the local frame offset by the
; LocalStackSlotAllocation pass at offset 4096.
;
; The %load1 access to %gep.large.offset initially used the stack
; pointer register and directly referenced the frame index. After
; LocalStackSlotAllocation, it would no longer refer to a frame index
; so eliminateFrameIndex would not adjust the access to use the
; correct FP offset.
