            Bug ID: 19364
           Summary: 4 unneeded zero byte after movq *0xfa(r3),*0x68
                    assembled (VAX)
           Product: binutils
           Version: 2.25
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gas
          Assignee: unassigned at sourceware dot org
          Reporter: SztfG at yandex dot ru
  Target Milestone: ---

Vax assembler

Code:

  .text
  movq *0xfa(%r3), *$0x68
  movq %r1, %r2

after assembling and objdumping I got this:

  00000000 <.text>:
   0:   7d d3 fa 00     movq *0xfa(r3),*0x68
   4:   9f 68 00 00 
   8:   00 
   9:   00              halt
   a:   00              halt
   b:   00              halt
   c:   00              halt
   d:   7d 51 52        movq r1,r2

Why I have those 4 halt instructions? Bug?
If it's not a bug, how to get rid of this zeros?
