Hi,
This patch rewrites nonlinear iv_use by re-associating invariant part and
induction part separately so that invariant expressions are exposed to
later lim pass.
Is it OK?

Thanks,
bin

	* tree-ssa-loop-ivopts.c (rewrite_use_nonlinear_expr): Re-associate
	nonlinear iv_use computation in loop invariant sensitive way.
