   1 /* Area:                ffi_call, closure_call
   2    Purpose:             Check structure returning with different structure size.
   3                                 Depending on the ABI. Check bigger struct which overlaps
   4                                 the gp and fp register count on Darwin/AIX/ppc64.
   5    Limitations: none.
   6    PR:                  none.
