From: Ian Romanick <ian.d.roman...@intel.com>
Withouth this, a pattern that creates a sequence that another pattern
can match will never perform the second match. This can mean either
lost optimization opportunity (and a lot of frustration... "Why the
%@#$ isn't my optimization happening?!?") or, even worse, missed
lowering.
No shader-db changes on any platform.
