Hi! I've committed this patch on mainline to be able to read/write the 68HC12 page register. The patch also fixes register sizes since A, B and CCR are 8-bit wide (but it doesn't matter very much...) Stephane 2002-08-13 Stephane Carrez * m68hc11-tdep.c (HARD_PAGE_REGNUM): Define for 68HC12 page register. (M68HC11_LAST_HARD_REG, m68hc11_register_names): Update. (m68hc11_register_virtual_type): Return a 8-bit type for 8-bit registers. (m68hc11_register_raw_size): Likewise.
