tree.def (BIT_FIELD_REF): Constrain result type and its precision.
2008-03-06 Richard Guenther <rguenther@suse.de> * tree.def (BIT_FIELD_REF): Constrain result type and its precision. * tree-cfg.c (verify_expr): Verify BIT_FIELD_REF constraints on result type and precision. * expr.c (get_inner_reference): Set unsignedp based on the result type of BIT_FIELD_REF. * tree.h (BIT_FIELD_REF_UNSIGNED): Remove. * tree-sra.c (instantiate_element): Do not set BIT_FIELD_REF_UNSIGNED. (try_instantiate_multiple_fields): Likewise. Use the correct type for BIT_FIELD_REF. (sra_build_assignment): Likewise. (sra_build_elt_assignment): Likewise. (sra_explode_bitfield_assignment): Likewise. * print-tree.c (print_node): Do not check BIT_FIELD_REF_UNSIGNED. * tree-vect-transform.c (vect_create_epilog_for_reduction): Do not set BIT_FIELD_REF_UNSIGNED. (vectorizable_load): Likewise. From-SVN: r132969
