[Bug target/36684] [4.3/4.4 Regression] spill failure for class 'R0_REGS' on sh4 with -fPIC -O2

[kkojima at gcc dot gnu dot org]

------- Comment #3 from kkojima at gcc dot gnu dot org  2008-07-01 23:59 -------
A reduced testcase:

typedef int (proc) (int *interp, void *data);
typedef struct
{
  void *func;
  void *data;
} InterStruct;

extern InterStruct simple;
extern int simple_interactor ();
static proc *interactor = simple_interactor;


InterStruct Interactor(void *interp, proc inter_proc)
{
  InterStruct tmp = simple;
  interactor = (inter_proc ? inter_proc : simple_interactor);
  return tmp;
}
