gcc4.0 autovect-branch

[Villemin Ryusuke]

Hi,

I might be missing something simple and obvious, but I can't find out what :
I picked up gcc4.0 in the autovect-branch, compiled it successfully but can t make it vectorize anything.

int a[256], b[256], c[256];

foo () {
  int i;
  for (i=0; i<256; i++){
    a[i] = b[i] + c[i];
  }
}

compiled with :
"gcc -O2 -msse2 -ftree-vectorize -fdump-tree-vect-stats vecto.c".

I expect to see a "LOOP VECTORIZED." (or at least "not vectorized:"), but I have nothing...

Any ideas ?

Thank you,
