virtual void dom_walker::after_dom_children ( basic_block  )
void mark_def_dom_walker::before_dom_children ( basic_block  bb)
   Block processing routine for mark_def_sites.  Clear the KILLS bitmap
   at the start of each block, and call mark_def_sites for each statement.  

Reimplemented from dom_walker.

References gimple_bb(), and mark_block_for_update().

void dom_walker::walk ( basic_block  bb)
     Walk the dominator tree.  
   Recursively walk the dominator tree.
   BB is the basic block we are currently visiting.  
         Don't worry about unreachable blocks.  
             Callback for subclasses to do custom things before we have walked
             the dominator children, but before we walk statements.  
             Mark the current BB to be popped out of the recursion stack
             once children are processed.  
         NULL is used to mark pop operations in the recursion stack.  
             Callback allowing subclasses to do custom things after we have
             walked dominator children, but before we walk statements.

Field Documentation

bitmap mark_def_dom_walker::m_kills
     Notice that this bitmap is indexed using variable UIDs, so it must be
     large enough to accommodate all the variables referenced in the
     function, not just the ones we are renaming.
