Question on scalar replacement

    Sounds like a bug.  Give us a test case and we can look at it.

See above.  The problem is that there are a lot of unchecked-in
sources.  I'll check in the (few) Ada changes soon, but I'm not sure
what to do with the middle-end changes since they aren't yet fully debugged.

    All functions have comments in front of them.  What are you looking for?

An overview of a few paragraphs saying what, in general terms, the
optimization is doing at a level enough to allow somebody to construct
an example of the optimization (or perhaps give the example).  Also, some
general statements, again at a high level, of how the optimization is done
and calling out the major functions used in the optimization and
important data structures, if any.
