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.
