Removing some abstractions to make it more amenable to other passes:
removing binding contours, making exception handling explicit, etc.  In
the future it may include exposing address arithmetic and anything we
may find useful for future optimizations.

I discuss it (very) briefly in this year's Summit paper on tree-ssa and
it's described in doc/passes.texi.

Sorry, the description is vague, could you post a test case?


Thanks.  Diego.
