## movl foo@GOTPCREL(%rip), %eax

  .reloc .-4, R_X86_64_GOTPCRELX, foo-4

## The instruction has an offset (addend!=-4). It is incorrect to relax movl to leal.
## movl foo@GOTPCREL+4(%rip), %eax
  movl 0(%rip), %eax
  .reloc .-4, R_X86_64_GOTPCRELX, foo

## This does not make sense because it loads one byte past the GOT entry.
## It is just to demonstrate the behavior.
