This bug must have been weaker than I remembered it; when I used 4 char fields
instead of one char[4], 4.4 behaved properly too.
How about:
Alexander Strange <astra...@ithinksw.com
PR tree-optimization/36318
* gcc.dg/tree-ssa/sra-7.c: New test.
/* { dg-do compile } */
/* { dg-options "-O1 -fdump-tree-sra-details" } */
typedef struct {char f[4];} __attribute__((aligned (4))) s;
void a(s *s1, s *s2)
{
*s1 = *s2;
}
/* Struct copies should not be split into members */
/* { dg-final { scan-tree-dump "= \\\*s2" "sra"} } */
/* { dg-final { cleanup-tree-dump "sra" } } */
I checked sra instead of esra since it runs last and this is a negative test.
Hopefully this is trivial?
