...t;` with elements forming
the arithmetic series:
`elt[z] = v1 + z * v2`
where `z` is the element index and `<ty>` a scalar type. This is primarily used
to represent a vector of induction values leading to:
* Predicate creation using vector compares for fully predicated loops (see also:
[*propff*](#propff), [*test*](#test)).
* Creating offset vectors for gather/scatter via `getelementptr`.
* Creating masks for `shufflevector`.
For the following loop, a seriesvector instruction based on `i` is used to
create the data vector to store:
```cpp
unsigned a[LIMIT];
for (unsigned i = 0; i &...

Hi Renato,
Sorry for the delay in responding. We've been busy rethinking some of our changes after the feedback we've received thus far (particularly from the devmeeting). The incremental patches will use our revised design(which should be less invasive), and I'll be updating our document to match.
