Slightly reduced testcase:
int a[2], b, c, d, e;
void
foo (int x, int y)
{
}
int
bar (void)
{
int i;
for (; d <= 0; d = 1)
for (i = 0; i < 4; i++)
for (e = 0; e; e = 1)
;
return 0;
}
int
main ()
{
for (b = 0; b < 2; b++)
while (c)
foo (a[b] = 0, bar ());
return 0;
}

Created attachment 24742
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=24742
gcc47-pr49712.patch
Untested fix.
Wonder if TARGET_MEM_REF shouldn't be handled alongside MEM_REF in
ref_always_accessed_p too.
