The test is failing on my side when building with --target=x86_64-elf.
I'm not sure what's wrong yet but gas seems to ignore everything after "/":
  | $ ../../binutils/objdump  -drw tmpdir/x86-64-opcode.o
  |  ...
  |  4ea: f6 f7                div    %bh
  |  4ec: f7 f7                div    %edi
  |  4ee: c0 c1 c1              rol    $0xc1,%cl
  |  4f1: d0 d1                rcl    %cl
  |  4f3: d1 d2                rcl    %edx
  |  4f5: d3 d3                rcl    %cl,%ebx
