[PATCH] Fix addr2line and -msym32 and mips64 (Linux kernel)

[Andrew Pinski <pinskia at gmail dot com>]

Hi,
  After
	2011-03-30  Catherine Moore  <clm@codesourcery.com>

	* addr2line.c (translate_addresses): Sign extend the pc
	if sign_extend_vma is enabled.

Using addr2line is broken on mips64-linux-gnu with the Linux kernel (-msym32).
The pc becomes all -1.  The reason is ((bfd_vma) -1) <<
bed->s->arch_size produces an undefined value as bed->s->arch_size is
64 so shifting by left by more than 63 is undefined.
The attached patch fixes the problem by not doing the sign extending
if the size of bfd_vma is equal to or less than the arch size.

OK?  Tested on mips64-linux-gnu and x86_64-linux-gnu.

Thanks,
Andrew Pinski

	* addr2line.c (translate_addresses): Don't try to
	sign extend the pc if the sizeof vma is less or equal
	to the arch_size.
