re PR tree-optimization/34371 (verify_stmts failed (incorrect sharing of tree nodes))
PR tree-optimization/34371
* tree-vectorizer.h (struct _loop_vec_info): Add num_iters_unchanged
field.
(LOOP_VINFO_NITERS_UNCHANGED): Define to num_iters_unchanged field.
* tree-vectorizer.c (set_prologue_iterations,
slpeel_tree_peel_loop_to_edge): Call unshare_expr on
LOOP_VINFO_NITERS_UNCHANGED before using it.
* gcc.c-torture/compile/20071207-1.c: New test.
