* config/mcore/tm-mcore.h (GDB_MULTI_ARCH): Set to 2.
(PR_REGNUM, FIRST_ARGREG, LAST_ARGREG,RETVAL_REGNUM): Move to mcore-tdep. (REG_STRUCT_HAS_ADDR, USE_STRUCT_CONVENTION, GET_SAVED_REGISTER) (TARGET_VIRTUAL_FRAME_POINTER, BELIEVE_PCC_PROMOTION): Remove. * mcore-tdep.c (PR_REGNUM, FIRST_ARGREG, LAST_ARGREG) (RETVAL_REGNUM): Move macros from tm-mcore.h (mcore_reg_struct_has_addr): New function. (mcore_gdbarch_init): Added initializations for the macros removed from tm-mcore.h.
