B::Bblock(3pm)	       Perl Programmers Reference Guide		B::Bblock(3pm)

NAME
       B::Bblock - Walk basic blocks

SYNOPSIS
	 # External interface
	 perl -MO=Bblock[,OPTIONS] foo.pl

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

DESCRIPTION
       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.

       Functions

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

	   Given the root of the op tree and an op from which to start pro‐
	   cessing, it will return a hash ref representing all the ops which
	   start a block.

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