re PR target/34856 (ICE with some constant vectors) 

2008-01-21  Richard Guenther  <rguenther@suse.de>

	PR middle-end/34856
	* tree-cfg.c (verify_expr): Allow all invariant expressions
	instead of just constant class ones as reference argument.
	* tree-ssa-loop-im.c (for_each_index): Handle CONSTRUCTOR
	like any other constant.
	* tree-ssa-sccvn.c (copy_reference_ops_from_ref): Likewise.

	* gcc.c-torture/compile/pr34856.c: New testcase.
