c595d67311 Speed up Verilator itself by prefetching pointer-chase 2008-11-22 14:59:22 -05:00

8b77379e2c Internal coding: Assert that user#() don't overlap. 
Any use of a user() must now be declared, generally in the Visitor class with
    AstUser#InUse   arbitrary_object
This lets the code track if there's another request for the same user(),
preventing nasty hard to debug cases where they overlap.  This will also
call user#ClearTree(), so a bunch of those were removed, though many
extranious ones still remain.
