2017-05-30S/390: Improve error checking for optional operandsAndreas Krebbel1-1/+10
So far we only had an instruction flag which made an arbitrary number of operands optional. This limits error checking capabilities for instructions marked that way. With this patch the optparm flag only allows a single optional parameter and another one is added (optparm2) allowing 2 optional arguments. Hopefully we won't need more than that in the future. So far there will be only a single use of optparm2. gas/ChangeLog: 2017-05-30 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * config/tc-s390.c (md_gather_operands): Support new optparm2 instruction flag. include/ChangeLog: 2017-05-30 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * opcode/s390.h: Add new instruction flags optparm2. opcodes/ChangeLog: 2017-05-30 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * s390-dis.c (s390_print_insn_with_opcode): Support new optparm2 instruction flag. * s390-mkopc.c (main): Recognize the new instruction flag when parsing instruction list.
2017-05-24Move print_insn_XXX to an opcodes internal headerYao Qi1-1/+1
With the changes done in previous patches, print_insn_XXX functions don't have to be external visible out of opcodes, because both gdb and objdump select disassemblers through a single interface. This patch moves these print_insn_XXX declarations from include/dis-asm.h to opcodes/disassemble.h, which is a new header added by this patch. include: 2017-05-24 Yao Qi <yao.qi@linaro.org> * dis-asm.h: Move some function declarations to opcodes/disassemble.h. opcodes: 2017-05-24 Yao Qi <yao.qi@linaro.org> * alpha-dis.c: Include disassemble.h, don't include dis-asm.h. * avr-dis.c, bfin-dis.c, cr16-dis.c: Likewise. * crx-dis.c, d10v-dis.c, d30v-dis.c: Likewise. * disassemble.c, dlx-dis.c, epiphany-dis.c: Likewise. * fr30-dis.c, ft32-dis.c, h8300-dis.c, h8500-dis.c: Likewise. * hppa-dis.c, i370-dis.c, i386-dis.c: Likewise. * i860-dis.c, i960-dis.c, ip2k-dis.c: Likewise. * iq2000-dis.c, lm32-dis.c, m10200-dis.c: Likewise. * m10300-dis.c, m32r-dis.c, m68hc11-dis.c: Likewise. * m68k-dis.c, m88k-dis.c, mcore-dis.c: Likewise. * metag-dis.c, microblaze-dis.c, mmix-dis.c: Likewise. * moxie-dis.c, msp430-dis.c, mt-dis.c: * nds32-dis.c, nios2-dis.c, ns32k-dis.c: Likewise. * or1k-dis.c, pdp11-dis.c, pj-dis.c: Likewise. * ppc-dis.c, pru-dis.c, riscv-dis.c: Likewise. * rl78-dis.c, s390-dis.c, score-dis.c: Likewise. * sh-dis.c, sh64-dis.c, tic30-dis.c: Likewise. * tic4x-dis.c, tic54x-dis.c, tic6x-dis.c: Likewise. * tic80-dis.c, tilegx-dis.c, tilepro-dis.c: Likewise. * v850-dis.c, vax-dis.c, visium-dis.c: Likewise. * w65-dis.c, wasm32-dis.c, xc16x-dis.c: Likewise. * xgate-dis.c, xstormy16-dis.c, xtensa-dis.c: Likewise. * z80-dis.c, z8k-dis.c: Likewise. * disassemble.h: New file.
2017-02-28GDB: Add support for the new set/show disassembler-options commands.Peter Bergner1-15/+57
This commit adds support to GDB so that it can modify the disassembler-options value that is passed to the disassembler, similar to objdump's -M option.

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.
