Good. So I understand that whole-program analysis and optimizations
can be developed in gcc based on -fwhole-program. My plans are to
implement interprocedural (whole program) constant propagation using
a context insensitive approach. I want to apply this to the stage
where the call-graph is available, prior to (and possibly guiding)
inlining; right now (gcc3.4) it seems best to work at the generic
tree level (where the call-graph is available), but maybe it's better
to work on gimple in tree-ssa branch?
