define ptr @test_null_base_normal() {

Transformation seems to be correct! (syntactically equal)

define ptr @test_null_base_normal() {

  %__constexpr_0 = inttoptr i16 65534 to ptr
  ret ptr %__constexpr_0

Transformation doesn't verify! (unsound)
ERROR: Value mismatch

NOTE: The counterexample is unique.

Example:

Source:
ptr %gep = pointer(non-local, block_id=0, offset=-2) / Address=#xfffe

SOURCE MEMORY STATE
===================
NON-LOCAL BLOCKS:
Block 0 >	size: 0	align: 1	alloc type: 0	alive: false	address: #x0000

Target:
ptr %__constexpr_0 = phy-ptr(addr=65534) / Address=#xfffe

TARGET MEMORY STATE
===================
NON-LOCAL BLOCKS:
Block 0 >	size: 0	align: 1	alloc type: 0	alive: false	address: #x0000
Source value: pointer(non-local, block_id=0, offset=-2) / Address=#xfffe
Target value: phy-ptr(addr=65534) / Address=#xfffe
