Add support for the AVR Tiny series of microcontrollers.
* archures.c: add avrtiny architecture for avr target. * bfd-in2.h: Regenerate. * cpu-avr.c (arch_info_struct): add avrtiny arch info. * elf32-avr.c (elf_avr_howto_table): new relocation R_AVR_LDS_STS_16 added for 16 bit LDS/STS instruction of avrtiny arch. (avr_reloc_map): reloc R_AVR_LDS_STS_16 is mapped to BFD_RELOC_AVR_LDS_STS_16. (bfd_elf_avr_final_write_processing): select machine number avrtiny arch. (elf32_avr_object_p): set machine number for avrtiny arch. * libbfd.h: Regenerate. * reloc.c: Add documentation for BFD_RELOC_AVR_LDS_STS_16 reloc. * config/tc-avr.c (mcu_types): Add avrtiny arch. Add avrtiny arch devices attiny4, attiny5, attiny9, attiny10, attiny20 and attiny40. (md_show_usage): Add avrtiny arch in usage message. (avr_operand): validate and issue error for invalid register for avrtiny. add new reloc exp for 16 bit lds/sts instruction. (md_apply_fix): check 16 bit lds/sts operand for out of range and encode. (md_assemble): check ISA for arch and issue diagnostic. * include/elf/avr.h (E_AVR_MACH_AVRTINY): define avrtiny machine number. (R_AVR_LDS_STS_16): define 16 bit lds/sts reloc number. * include/opcode/avr.h (AVR_ISA_TINY): define avrtiny specific ISA. (AVR_ISA_2xxxa): define ISA without LPM. (AVR_ISA_AVRTINY): define avrtiny arch ISA. Add doc for contraint used in 16 bit lds/sts. Adjust ISA group for icall, ijmp, pop and push. Add 16 bit lds/sts encoding and update 32 bit lds/sts constraints. * opcodes/avr-dis.c (avr_operand): Handle constraint j for 16 bit lds/sts. (print_insn_avr): do not select opcode if insn ISA is avrtiny and machine is not avrtiny. * Makefile.am (ALL_EMULATION_SOURCES): add avrtiny emulation source. (eavrtiny.c): add rules for avrtiny emulation source. * Makefile.in: Regenerate. * configure.tgt: Add avrtiny to avr target emulations. * scripttempl/avrtiny.sc: New file. linker script template for avrtiny arch. * emulparams/avrtiny.sh: New file. emulation parameters for avrtiny arch.
