The patch in comment #3 broke the (previously passing) test for all ix86
targets. It seems strange to try and remedy that by disabling the test for
nonpic targets (as the change at r163685

Well, scans definitely pass on x86_64 AND i686 linux without -fpic.
Why it fails for the -fpic targets should be clear from the assembly dumps.
The fix you are referring to added

Add:

to the testcase.

This is testsuite problem, on x86_64 we have:
movl$0, obj_5(%rip)
movlobj_5(%rip), %eax
vs.
movl$0, obj_5
movlobj_5, %eax
on x86_32.
So, scan patterns should be updated

Thanks Uros. Could you prepare a patch to match the x86_64 output -- given you
have the hardware?
