[Bug other/18163] New: libffi test case ICE's on darwin

[andreast at gcc dot gnu dot org]

The following test case ICE's on darwin since 2004-10-26. Before it was ok.

/Volumes/src/gcc/gcc-cvs/gcc/libffi/testsuite/libffi.call/return_ldsum.c:64:
error: unrecognizable insn:^M(insn 15 14 16 0 (set (reg:TI 158 [ g ])^M       
(const_int 0 [0x0])) -1 (nil)^M   
(nil))^M/Volumes/src/gcc/gcc-cvs/gcc/libffi/testsuite/libffi.call/return_ldsum.c:64:
internal compiler error: in extract_insn, at recog.c:2034^M

I attach the test case asap. It is not yet committed to cvs.

Confirmed, here is the reduced testcase:
long double return_ld(long double a, long double b, long double c,
			     long double d, long double e, long double f,
			     long double g)
{
  return a + b + c + d + e + f + g;
}

Something changed between:

        * expr.c (emit_group_load): Handle floats.
        (emit_group_store): Same.

Note the solution for a different related problem in <http://gcc.gnu.org/ml/gcc/2004-10/
msg01025.html> will not work as the mode in this case is still a floating point mode (TF) and the 
corresponding int mode is TI which does not exist on ppc.
