       B::Bblock - Walk basic blocks

         # External interface
         perl -MO=Bblock[,OPTIONS]

         # Programmatic API
         use B::Bblock qw(find_leaders);
         my $leaders = find_leaders($root_op, $start_op);

       This module is used by the B::CC back end.  It walks "basic blocks".  A basic block is a series of operations
       which is known to execute from start to finish, with no possibility of branching or halting.

       It can be used either stand alone or from inside another program.


             my $leaders = find_leaders($root_op, $start_op);

           Given the root of the op tree and an op from which to start processing, it will return a hash ref repre-
           senting all the ops which start a block.

           The values of %$leaders are the op objects themselves.  Keys are $$op addresses.
