Add new ARCv3 CPUs and required bits to decode/encode ARCv3 ISA opcodes. Fix 32 bit relocations which were set as signed but should be bitfield: ARC_32_ME, ARC_GLOB_DAT, ARC_JMP_SLOT, ARC_RELATIVE. Remove non-ABI relocation ARC_32_ME_S. include/ xxxx-xx-xx Claudiu Zissulescu <claziss@synopsys.com> Cupertino Miranda <cupertinomiranda@gmail.com> Bruno Mauricio <brunoasmauricio@gmail.com> * include/elf/arc-cpu.def: Add new HS5x and HS6x CPUs. * include/elf/arc-reloc.def: Add new ARC64 relocations. * include/elf/arc.h (EF_ARC_CPU_ARC64): New define. * include/opcode/arc-attrs.h (FEATURE_LIST_NAME): Update predicate. * include/opcode/arc-func.h: Update formating.
