Return NULL_RTX instead of NULL. * reg-stack.c (emit_swap_insn): Eliminate warnings. (subst_asm_stack_regs): Likewise. * combine.c (num_sign_bit_copies): Cast bitwidth to int to avoid warnings. * dwarf2out.c (output_call_frame_info): Declare i as int. (build_abbrev_table): Declare n_alloc as int. (dwarf2out_finish): Initialize die. * except.c: Declare sjlj_funcdef_number as unsigned. (connect_post_landing_pads): Declare j as unsigned. (convert_to_eh_region_ranges): Initialize call_site. (output_function_exception_table): Initialize tt_format_size. * expr.c (move_by_pieces_1): Initialize to1. (store_constructor): Initialize minelt and maxelt. * flow.c (mark_regs_live_at_end): Declare i as unsigned. * function.c (instantiate_decls): Avoid signed/unsigned warning. * c-decl.c (combine_parm_decls): Unused, remove. * c-tree.h: Remove prototype for combine_parm_decls. * reload.c (push_reload): Fix warning. (regno_clobbered_p): Likewise. * reload1.c (replace_pseudos_in_call_usage): Likewise. (reload_combine): Likewise. * bitmap.c: Rename bitmap_zero to bitmap_zero_bits to fix warnings. * bitmap.h: Rename bitmap_zero to bitmap_zero_bits to fix warnings. * bitmap.c (bitmap_operation): Change user. * bitmap.h (EXECUTE_IF_AND_COMPL_IN_BITMAP): Likewise. For cp/: 2001-07-10 Jan van Male * call.c (build_op_delete_call): Initialize fn. (convert_like_real): Delete conditional. (joust): Initialize *w and *l. * class.c: Add prototype for binfo_ctor_vtable. (get_primary_binfo): Initialize result. * init.c (build_java_class_ref): Initialize name. * typeck.c (unary_complex_lvalue): Do not duplicate the argument to modify, pre-, or post-increment when used as an lvalue and when the argument has side-effects. For ch/: 2001-07-10 Jan van Male * ch-tree.h: Remove prototype for combine_parm_decls, unused function.
