Andrew,

If you are right about all those tree walks, check out my fix for 1687 (3.3 branch only, 3.4 is in the works).
http://gcc.gnu.org/PR1687.  The idea is to simply use walk_tree_without_duplicates.  Our front ends tend to produce horrible convoluted trees that makr walk_tree walks really slow sometimes.

Gr.
Steven
