SRA does not work for structs that contain an array.
This is a known issue, filed so that it can be tracked.
/* { dg-do compile } */
/* { dg-options "-O1 -fdump-tree-optimized" } */
void link_error (void);
typedef struct teststruct
{
double d;
char f1;
int arr[15];
} teststruct;
void
copystruct5 (teststruct param)
{
teststruct local;
param.f1 = 0;
local = param;
if (local.f1 != 0)
link_error ();
}
/* There should be no reference to link_error. */

------- Additional Comments From pinskia at gcc dot gnu dot org 2004-01-31 21:16 -------
Confirmed from *.t24.sra:
Cannot scalarize variable param because it contains an aggregate type field, arr
Cannot scalarize variable local because it contains an aggregate type field, arr

Just like 13953:
param$f1_7 = param.f1;
param$f1_8 = 0;
param.f1 = param$f1_8;
local = param;
local$f1_10 = local.f1;
T.0_4 = local$f1_10;

Would be fixed by addressing the ??? in scalarize_copy wrt use_block_copy.

Optimizes to an empty function for me with r162374.
Probably thanks to Martin's SRA rewrite.
