[Bug 1027454] Re: misdisassembly/and seg of ARM on 32bit hosts

[C de-Avillez]

running on a pandaboard, binutils 2.22-6ubuntu1:

ubuntu at panda-quantal:~$ perl -e 'print pack("V*", 0xed69cdcb)' >/tmp/bad.insn
ubuntu at panda-quantal:~$ objdump -b binary -m arm -EL -D /tmp/bad.insn

/tmp/bad.insn:     file format binary


Disassembly of section .data:

00000000 <.data>:
   0:	ed69cdcb 	stcl	13, cr12, [r9, #-812]!	; 0xfffffcd4
ubuntu at panda-quantal:~$

dist-upgrading now, and will try again.

Title:
  misdisassembly/and seg of ARM on 32bit hosts

Status in binutils:
  Unknown
Status in “binutils” package in Ubuntu:
  New

Bug description:
  This corresponds to binutils bug
  http://sourceware.org/bugzilla/show_bug.cgi?id=13135

  There are mismatched printf formats and arguments that cause segs or incorrect offsets in ARM disassembly in
  binutils 2.22; the simplest example (on 32bit x86 Quantal) from the upstream bug is:

  
  % perl -e 'print pack("V*", 0xed69cdcb)' >/tmp/bad.insn
  % objdump -b binary -m arm -EL -D /tmp/bad.insn
