re PR middle-end/43631 (var-tracking inserts notes with non-NULL BLOCK_FOR_INSN in between basic blocks) PR middle-end/43631 * emit-rtl.c (make_note_raw): New function. (link_insn_into_chain): New static inline function. (add_insn): Use it. (add_insn_before, add_insn_after): Factor insn chain linking code... (add_insn_before_nobb, add_insn_after_nobb): ...here, new functions using link_insn_into_chain. (note_outside_basic_block_p): New helper function for emit_note_after and emit_note_before. (emit_note_after): Use nobb variant of add_insn_after if the note should not be contained in a basic block. (emit_note_before): Use nobb variant of add_insn_before if the note should not be contained in a basic block. (emit_note_copy): Use make_note_raw. (emit_note): Likewise. * bb-reorder.c (insert_section_boundary_note): Remove hack to set BLOCK_FOR_INSN to NULL manually for NOTE_INSN_SWITCH_TEXT_SECTIONS. * jump.c (cleanup_barriers): Use reorder_insns_nobb to avoid making the moved barrier the tail of the basic block it follows. * var-tracking.c (pass_variable_tracking): Add TODO_verify_flow.
