2016-06-10S/390: Dump unknown instructions according to their length.Andreas Krebbel1-17/+38
Unknown instructions are currently just dumped as .long 1234. On S/390 we can do a bit better since the instruction length is encoded in the opcode. That way also unknown instructions can be skipped according to their real length. That way we can continue correctly after that instruction. However, there are also some drawbacks with that behavior when dumping data. So for now that behavior is only enabled for text section but even there it might mess things up when having a literal pool embedded in the code. Therefore I've left the feature disabled by default and have added the -Minsnlength option to enable it explicitely. opcodes/ChangeLog: 2016-06-10 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * s390-dis.c (option_use_insn_len_bits_p): New file scope variable. (init_disasm): Handle new command line option "insnlength". (print_s390_disassembler_options): Mention new option in help output. (print_insn_s390): Use the encoded insn length when dumping unknown instructions.

2013-10-30S/390: Disassemble 31-bit binaries with "zarch" opcode set by defaultAndreas Arnez1-11/+1
Currently the disassembler for s390 (by default) assumes that a 31-bit binary was compiled in "ESA" mode -- and then only disassembles a limited opcode set. The change upgrades the default to the full "zarch" opcode set even for 31-bit binaries. opcodes/ * s390-dis.c (init_disasm): Default to full 'zarch' opcode availability even for 31-bit programs.
