FT32 initial support
FT32 is a new 32-bit RISC core developed by FTDI for embedded applications. * configure.ac: Add FT32 support. * configure: Regenerate. bfd/ * Makefile.am: Add FT32 files. * archures.c (enum bfd_architecture): Add bfd_arch_ft32. (bfd_mach_ft32): Define. (bfd_ft32_arch): Declare. (bfd_archures_list): Add bfd_ft32_arch. * config.bfd: Handle FT32. * configure.ac: Likewise. * cpu-ft32.c: New file. * elf32-ft32.c: New file. * reloc.c (BFD_RELOC_FT32_10, BFD_RELOC_FT32_20, BFD_RELOC_FT32_17, BFD_RELOC_FT32_18): Define. * targets.c (_bfd_target_vector): Add ft32_elf32_vec. * bfd-in2.h: Regenerate. * libbfd.h: Regenerate. * Makefile.in: Regenerate. * configure: Regenerate. * po/SRC-POTFILES.in: Regenerate. binutils/ * readelf.c: Add FT32 support. gas/ * Makefile.am: Add FT32 files. * config/tc-ft32.c: New file. * config/tc-ft32.h: New file. * configure.tgt: Add FT32 support. * Makefile.in: Regenerate. * po/POTFILES.in: Regenerate. gas/testsuite/ * gas/ft32/ft32.exp: New file. * gas/ft32/insn.d: New file. * gas/ft32/insn.s: New file. include/ * dis-asm.h (print_insn_ft32): Declare. include/elf/ * common.h (EM_FT32): Define. * ft32.h: New file. include/opcode/ * ft32.h: New file. ld/ * Makefile.am: Add FT32 files. * configure.tgt: Handle FT32 target. * emulparams/elf32ft32.sh: New file. * scripttempl/ft32.sc: New file. * Makefile.in: Regenerate. opcodes/ * Makefile.am: Add FT32 files. * configure.ac: Handle FT32. * disassemble.c (disassembler): Call print_insn_ft32. * ft32-dis.c: New file. * ft32-opc.c: New file. * Makefile.in: Regenerate. * configure: Regenerate. * po/POTFILES.in: Regenerate.
