--- Comment #8 from Richard Biener <rguenth at gcc dot gnu.org> ---
On branches this is latent wrong-code as we simply do
/* Propagate the RHS into every use of the LHS. */
FOR_EACH_IMM_USE_STMT (use_stmt, iter, lhs)
FOR_EACH_IMM_USE_ON_STMT (use_p, iter)
SET_USE (use_p, var);
there. OTOH we only see unpropagated vars there so we are restoring the
original
IL. I changed it to replace_uses_by to get stmts folded properly to avoid
non-canonical operand order and non-canonical MEMs after propagation.
I'll conditionally restore the above.
