[ARC] Force the disassam to use the hexadecimal number for printing
Force printing of the short/signed values using hexadecimal representation via disassembler option. opcode/ 2017-11-03 Claudiu Zissulescu <claziss@synopsys.com> * arc-dis.c (print_hex): New variable. (parse_option): Check for hex option. (print_insn_arc): Use hexadecimal representation for short immediate values when requested. (print_arc_disassembler_options): Add hex option to the list. binutils/ 2017-11-03 Claudiu Zissulescu <claziss@synopsys.com> * doc/binutils.texi (ARC): Update disassembler options. * testsuite/binutils-all/arc/hexprint.s: New file. * testsuite/binutils-all/arc/objdump.exp: Test hex printing feature.
