# Test the R_ARM_THM_JUMP11 (102) and R_ARM_THM_JUMP8 (103) relocations to an
# undefined weak reference. It should resolve to the next instruction, which
# is an offset of -2 which when added to the Thumb PC-bias of 4 is +2. We can't
# use llvm-mc to construct the object as it relaxes b.n to b.w (R_ARM_JUMP24).
