[Bug binutils/10297] New: inconsistencies in objdump's presentation of undefined's and comments

[chris at seberino dot org]

Here is a Python script that creates a raw binary and runs objdump on it to
reproduce the problem with the output following...

# ========================================================================
import commands
raw_binary = open("raw_binary", "w")
raw_binary.write(chr(0x1f) + chr(0x19) + chr(0x42) + chr(0xc3))
raw_binary.write(chr(0x6d) + chr(0xe8) + chr(0x6e) + chr(0x50))
raw_binary.write(chr(0x17) + chr(0x23) + chr(0xa9) + chr(0xb7))
raw_binary.write(chr(0x77) + chr(0xce) + chr(0x1b) + chr(0xf9))
raw_binary.close()
print commands.getoutput("objdump -D --target=binary -m arm7tdmi raw_binary")
# ========================================================================

% python foo.py 

raw_binary:     file format binary


Disassembly of section .data:

00000000 <.data>:
   0:   c342191f        cmpgt   r2, #507904     ; 0x7c000
   4:   506ee86d        rsbpl   lr, lr, sp, ror #16
   8:   b7a92317        undefined
   c:   f91bce77        undefined instruction 0xf91bce77

-----

Notice that the first 2 instructions have a immediate value but only the first
once has a comment with the hex equivalent.  

Also, notice the last 2 instructions are both undefined's yet only the last one
repeats the hex representation of the instruction.
