re PR tree-optimization/46723 (internal compiler error: in get_initial_def_for_induction, at tree-vect-loop.c:2431)
2010-12-02 Richard Guenther <rguenther@suse.de>
PR tree-optimization/46723
* tree-vect-loop.c (get_initial_def_for_induction): Strip
conversions from the induction evolution and apply it to
the result instead.
* tree-vect-stmts.c (vect_get_vec_def_for_operand): Handle
assigns for induction defs.
* gcc.dg/torture/pr46723.c: New testcase.
