gcj non-optimization curiosity

Sun Dec 16 13:40:00 GMT 2001

One other point: These optimizations are perhaps best done at the
tree level, rather than the rtx level, because of the high-level
semantics involved. Tree-based optimization passes are fairly
new in ccc. I don't know if there is any general framework,
or if we would have to start from scratch.
A related point: When compiling from bytecodes, we generate trees
at the statement level, but not ta the function level. That should
be fixed, but is a non-trival task
