; POOL_RANGE is how far away from a constant pool entry that this insn

; reference the pool.

; Note that for Thumb constant pools the PC value is rounded down to the

; nearest multiple of four. Therefore, THUMB2_POOL_RANGE (and POOL_RANGE for

|

; NEG_POOL_RANGE is nonzero for insns that can reference a constant pool entry

; before its address. It is set to <max_range> - (8 + <data_size>).
