I have patches to this simplifying in a generic way that other passes can use.

------- Additional Comments From pinskia at gcc dot gnu dot org  2004-05-14 17:41 -------
Fixed by:
	* tree-ssa-forwprop.c (record_single_argument_cond_exprs): Accept
	new parameters for the statement and variable worklist as well
	as a bitmap of interesting SSA_NAMEs.  Walk over the statement
	worklist recording interesting variables in the variable worklist
	and bitmap.  Handle casts between integral and boolean types.
	(substitute_single_use_vars): Accept new parameters for the statement
	and variable worklist.  When a substitution is made add a new
	entry to the statement worklist.  Handle casts between integral
	and boolean types.
	(tree_ssa_forward_propagate_single_use_vars): Rework to pass
	worklists to children.  Iterate until the statement worklist
	is empty.
