(avr_arch): Add ARCH_AVR6. (avr_mcu_types): Add 'atmega2560' and 'atmega2561' entry. (initial_elimination_offset): Initialize and use 'avr_pc_size' instead of fixed value 2. (print_operand_address): Use gs() asm specifier instead of pm(). (avr_assemble_integer): (Ditto.). (avr_output_addr_vec_elt): (Ditto.). (print_operand): Handle "!" code. * gcc/gcc/config/avr/avr.h (TARGET_CPU_CPP_BUILTINS): Add __AVR_3_BYTE_PC__, __AVR_2_BYTE_PC__ and __AVR_HAVE_JMP_CALL__. (AVR_HAVE_EIJMP_EICALL): Define. (AVR_3_BYTE_PC): Redefine. (AVR_2_BYTE_PC): (Ditto.). (PRINT_OPERAND_PUNCT_VALID_P): Add '!' code. (LINK_SPEC): Add atmega2560 and atmega2561. (CRT_BINUTILS_SPEC): Add atmega2560 (crtm2560.o) and atmega2561 (crtm2561.o). * gcc/gcc/config/avr/avr.md (call_insn): Use eicall instead of icall for 3 byte PC devices. (call_value_insn): (Ditto.). (*tablejump_enh): Use eijmp instead of ijmp for 3 byte PC devices. (indirect_jump): Use only for for 2 byte PC devices. (*tablejump): (Ditto.). (*indirect_jump_avr6): Add insn. (*tablejump_rjmp): Don't use for 3 byte PC devices. * gcc/gcc/config/avr/libgcc.S (__prologue_saves__): Use eijmp instead of ijmp for 3 byte PC devices. (__tablejump2__): (Ditto.). * gcc/gcc/config/avr/t-avr (MULITLIB_OPTIONS): Add avr6 architecture. (MULITLIB_DIRNAMES): (Ditto.). (MULTILIB_MATCHES): Add atmega2560 and atmega2561 to list.
