[Bug binutils/3134] New: objdump incompletely decodes mov disp:32 instruction

[markus+sw at gyger dot org]

objdump doesn't correctly disassemble the alternate coding of
MOV.L ERs, @(d:32, ERd)

>From the Notes of Table 2.2 in the 2.4 Instruction Code
section of the Renesas H8S/2600 Series Programming Manual
http://documentation.renesas.com/eng/products/mpumcu/rej09b0139_h8s2600.pdf

"2. Bit 7 of the 4th byte of the MOV.L ERs, @(d:32,ERd) instruction
can be either 1 or 0."

To reproduce:
h8300-elf-as mov.s
h8300-elf-objdump -wd a.out
[...]
   0:   01 00 78 80 6b a0 00 00 00 00   mov.l   er0,@(0x0:32,er0)
   a:   01 00 78 80 6b a0 00 00 00 00   mov.l   er0,@(0x0:32,er0)
  14:   01 00                           .word   H'1,H'0
  16:   78 00 6b a0 00 00 00 00         mov.w   r0,@(0x0:32,er0)

Content of mov.s:
.h8300s
mov er0, @(0:32,er0)
.byte 1, 0, 0x78, 0x80, 0x6b, 0xa0, 0, 0, 0, 0
.byte 1, 0, 0x78, 0x00, 0x6b, 0xa0, 0, 0, 0, 0
