[Bug target/31334] Bad codegen for vector initializer with constants prop'd into a vector initializer

[pinskia at gcc dot gnu dot org]

------- Comment #6 from pinskia at gcc dot gnu dot org  2007-03-25 23:05 -------
Now the patch does not solve the following testcase:
int main1 (int X)
{
  int s = X;
  int i;
  for (i = 0; i < 96*16; i+=16)
    s += i;
  return s;
}


For this one to be fixed, we need to define an insn which does vec_duplicate as
an insn_and_split instead of expanding it up in the rs6000_expand_vector_init.
