re PR tree-optimization/33453 (ICE in build2_stat, at tree.c:3110 with -ftree-parallelize-loops=4 -ftree-vectorize)
PR tree-optimization/33453
* tree-data-ref.c (split_constant_offset): Use POINTER_PLUS_EXPR
for pointer addition.
* tree-parloops.c (canonicalize_loop_ivs): Likewise.
(separate_decls_in_loop_name): Copy DECL_GIMPLE_REG_P from var to
var_copy.
* gcc.c-torture/compile/20071203-1.c: New test.
