S/390: Disassemble 31-bit binaries with "zarch" opcode set by default
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.
