I don't understand this change (but I'm not a specialist of mode switching): currently the mode setting sequence is always emitted before the insns that need it but, with the change, if an insn right after a NOTE_BASIC_BLOCK note needs it, if will be emitted either before it (if insn_ptr is the insn) or after it (if insn_ptr is the NOTE_BASIC_BLOCK note). -- Eric Botcazou
