m68k (elf) gas dwarf problem

[Joel Sherrill <joel@OARcorp.com>]

Hi,

Ralf and I have been trying to track down a problem which I have
tracked down enough to now beg for help.  It might be a bug in
gas or in the source file but is at least not well reported
by gas since it only reports the last number in the file. :(

Attached is s1.s which is the complete preprocessed output of the
startup code for a MC68340 based board.  s2.s is a cutdown to
4 lines which seems to be giving the same error.

I am using binutils 2.14 but I am pretty sure Ralf is using a 2.15-ish
binutils and getting the same problem.  Anyone with an m68k/enf
target should be able to duplicate this with the attached files.

$ m68k-rtems4.7-as -mcpu32 s1.s
$ m68k-rtems4.7-as --gdwarf2 -mcpu32 s1.s
s1.s: Assembler messages:
s1.s:926: Error: unaligned opcodes detected in executable segment

So adding the --gdwarf2 results in the unaligned error.

Is this a bug or is something wrong with the assembly code?

Thanks.
