[Bug middle-end/41047] gcc.target/mips/memcpy-1.c failing

[rguenth at gcc dot gnu dot org]

------- Comment #3 from rguenth at gcc dot gnu dot org  2009-08-12 18:54 -------
We used to get

  memcpy (&c, &"12345678"[2], 6); [tail call]
  memcpy (&c, "123456", 6); [tail call]

for expansion, but now we get

  D.2386_1 = (const void * restrict) "123456";
  c.1_2 = (void * restrict) &c;
  memcpy (c.1_2, D.2386_1, 6); [tail call]

and

  D.2383_1 = (const void * restrict) "12345678";
  D.2384_2 = D.2383_1 + 2;
  c.0_3 = (void * restrict) &c;
  memcpy (c.0_3, D.2384_2, 6); [tail call]

it's probably me that caused this - will have a look and add a target
independent testcase.
