tests for DWARF location lists?

[Carl Burch]

   I'm Carl Burch, with the WDB team at HP.  We're looking at importing the
FSF code to read DWARF location lists, but searching the recent releases I
couldn't find any tests that exercise -O explicitly.  Do you run a full pass
at -O with gcc to exercise the location list support?  If not and we develop
some new tests, would you be interested in our contributing them (e.g, via
Steve Ellcey)?
