Member Function Documentation

virtual void dom_walker::after_dom_children ( basic_block  )

inlinevirtualinherited

Function to call after the recursive walk of the dominator children.

Reimplemented in eliminate_dom_walker, rewrite_update_dom_walker, strlen_dom_walker, rewrite_dom_walker, nontrapping_dom_walker, dom_opt_dom_walker, uncprop_dom_walker, and single_def_use_dom_walker.

void dse_dom_walker::before_dom_children ( basic_block  )

virtual

Function to call before the recursive walk of the dominator children.

Reimplemented from dom_walker.

void dom_walker::walk ( basic_block  bb )

inherited

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.
