I also have a small proposal for describing locations as function of the SIMD lane by
adding a DW_OP_push_simd_lane operator and introducing stack variants for piece
operators.
 
I have a write-up ready but wanted to wait until we have a public implementation.
Is that the right order?  Or would you rather want to review proposals right away.

We'd also want an unbounded piece operator to describe partially registerized
unbounded arrays, but I have not worked that out in detail, yet, and we're a bit
farther away from an implementation.

Regards,
Markus.
