8; %pin.low is allocated to offset 0.
9;
10; %local.area is assigned to the local frame offset by the
11; LocalStackSlotAllocation pass at offset 4096.
12;
13; The %load1 access to %gep.large.offset initially used the stack
14; pointer register and directly referenced the frame index. After
15; LocalStackSlotAllocation, it would no longer refer to a frame index
16; so eliminateFrameIndex would not adjust the access to use the
17; correct FP offset.
