------- Additional Comments From pinskia at gcc dot gnu dot org  2004-12-26 21:36 -------
Confirmed, this bug is related to __builtin_apply, I was waiting for this to be filed.  I wonder if there is 
something which can be done without disabling libobjc for arm-linux or just using libffi.

Here is the reduced testcase:
int *f(void)
{
  return __builtin_apply (0,0,0);
}

We are just going into an infinite loop:

emit-rtl.c:1352

The bug is in untyped_call.

We are trying to emit the following RTL:
(Set (reg:XF 115) (reg:XF 16 f0))

So maybe this bug is in the middle-end and related to the subreg work.

The problem is that there is no movxf.  So this is definitely a target problem.

Could you test the patch in <http://gcc.gnu.org/bugzilla/attachment.cgi?id=7827&action=view> and 
report back the results so I send in the patch since I don't have access to arm-linux and arm-elf will 
does not have this bug.

Looking at the history I think this is also a 3.4 release, so maybe the problem is using XFmode:
* arm.h (ENABLE_XF_PATTERNS): Delete.
* arm.md (addxf3, subxf3, mulxf3, divxf3, modxf3, negxf2, absxf2)
(sqrtxf2, floatsixf2, fix_truncxfsi2, truncxfsf2, truncxfdf2)
(extendsfxf2, extenddfxf2, movxf, cmpxf, cmpxf_insn)
(cmpxf_trap): Delete.
(movxf_hard_insn): Remove test of ENABLE_XF_PATTERNS.

Actually was just the removal of the define_expand, I think, I will try that simple patch and try to post it 
soon.

------- Additional Comments From rearnsha at gcc dot gnu dot org  2005-02-16 22:00 -------
Patch fixes untyped returns properly using sfm/lfm as appropriate to avoid
potential type-conversion traps and also fixs returning types larger than a word
in integer registers.  Should also work correctly for Thumb when values larger
than a word are returned.
