[Bug c/30582] New: 64-bit Darwin ABI does not support array field

[cqfu at transmeta dot com]

struct my_data {
  float f[3];
};

This struct should be passed/returned via three single precision floating-point
registers instead of via memory or integer registers when using the "-mabi=d64"
 option in accordance to the draft specs. 
(ref: http://gcc.gnu.org/ml/gcc-patches/2004-11/msg00673.html)

We think the bug might be introduced when the related code in rs6000.c was
rewritten in revision 95723 on 2005-02-28. That can be traced back to GCC4.0.2
