  Issue ID: 16914
   Summary: Add -mavx switch to generate AVX instructions instead
of SSE instructions
   Product: D
   Version: D2
  Hardware: All
OS: All
Status: NEW
  Severity: enhancement
  Priority: P1

Because they're smaller & faster, and they have 3 operands instead of 2. Note
that this is not necessarily supporting 32 byte vectors.

works as intended.
Template types must no coerce.

   Summary: Cannot deduce function from argument type when mixing

Sorry for the very generic title, didn't knew how to put it.

This snippet should compile:
```
T[] tail (T) (T[] v, in T[] i, out T[] o)
{
return v;
}

void main ()
{
const(char)[] p1, p2;
immutable(char)[] pi;
tail(p1, pi, p2);
}
```

As there is one possible instantiation for tail, which is `T=const(char)`.
But here the compiler fails to see it and spit out:
```
lol.d(11): Error: template lol.tail cannot deduce function from argument types
!()(const(char)[], string, const(char)[]), candidates are:
lol.d(1):lol.tail(T)(T[] v, in T[] i, out T[] o)
```

What DMD version ? Also see issue 16031.
