2017-05-30btrace: Remove constant arguments.Tim Wiederhake2-47/+51
2017-05-30btrace: Use function segment index in insn iterator.Tim Wiederhake4-29/+50
Remove FUNCTION pointer in struct btrace_insn_iterator and use an index into the list of function segments instead.
2017-05-30btrace: Use function segment index in call iterator.Tim Wiederhake4-119/+101
Remove FUNCTION pointer in struct btrace_call_iterator and use an index into the list of function segments instead.
2017-05-30btrace: Add btinfo to instruction interator.Tim Wiederhake3-0/+12
This will serve as the access path to the vector of function segments once the FUNCTION pointer in struct btrace_insn_iterator is removed.
2017-05-30btrace: Transfer ownership of pointers.Tim Wiederhake2-48/+66
Directly insert new btrace_function pointers into the vector and have the vector own these pointers. This allows us to later retrieve these objects by their number directly after creation whereas at the moment we have to wait until the vector is fully populated. This requires to pull btrace_thread_info through different functions but cleans up the code for freeing the trace.

2017-05-30S/390: Improve error checking for optional operandsAndreas Krebbel4-8/+34
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.

2017-05-24Add unit test to gdbarch methods register_to_value and value_to_registerYao Qi6-0/+205
This patch adds one unit test for gdbarch methods register_to_value and value_to_register. The test pass different combinations of {regnu, type} to gdbarch_register_to_value and gdbarch_value_to_register. In order to do the test, add a new function create_new_frame to create a fake frame. It can be improved after we converted frame_info to class. In order to isolate regcache (from target_ops operations on writing registers, like target_store_registers), the sub-class of regcache in the test override raw_write. Also, in order to get the right regcache from get_thread_arch_aspace_regcache, the sub-class of regcache inserts itself to current_regcache.

This patch restricts alpha_convert_register_p from "TYPE_LENGTH (type) != 8" to "TYPE_LENGTH (type) == 4", because, - we have check "TYPE_LENGTH (valtype) == 4" in alpha_register_to_value and alpha_value_to_register, - alpha lds and sts instruction access 4 bytes, - comments "It might need to convert the [float] register into the corresponding [integer] type (see Alpha)" and integer is 4-byte on alpha, I think it is the right restrict condition to "TYPE_LENGTH (valtype) == 4". gdb: 2017-05-24 Yao Qi <yao.qi@linaro.org> * alpha-tdep.c (alpha_convert_register_p): Return true if type length is 4.

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.

2017-05-24Use disassemble.c:disassembler select rs6000 disassemblerYao Qi2-14/+5
Nowadays, rs6000 disassembler is selected in different ways in opcodes and gdb, opcodes: case bfd_arch_rs6000: if (mach == bfd_mach_ppc_620) disassemble = print_insn_big_powerpc; else disassemble = print_insn_rs6000; break; gdb: if (arch == bfd_arch_rs6000) set_gdbarch_print_insn (gdbarch, print_insn_rs6000); else set_gdbarch_print_insn (gdbarch, gdb_print_insn_powerpc); I am not sure which one is the right one. However, such selection should be done in one place instead of two. gdb: 2017-05-24 Yao Qi <yao.qi@linaro.org> * rs6000-tdep.c (gdb_print_insn_powerpc): Remove.

2017-05-24Use disassemble.c:disassembler select rl78 disassemblerYao Qi4-4/+15

2017-05-24Delegate opcodes to select disassembler in GDBYao Qi39-124/+73
This patch changes GDB to use disassembler selected by opcodes in default, so that we don't have to duplicate the selection logic again in GDB side. For example, gdb/score-tdep.c has static int score_print_insn (bfd_vma memaddr, struct disassemble_info *info) { if (info->endian == BFD_ENDIAN_BIG) return print_insn_big_score (memaddr, info); else return print_insn_little_score (memaddr, info); } and opcodes/disassemble.c has the same logic, case bfd_arch_score: if (big) disassemble = print_insn_big_score; else disassemble = print_insn_little_score; This patch removes the logic in GDB and calls opcodes/disassemble.c:disassembler in default to select disassembler. gdb: 2017-05-24 Yao Qi <yao.qi@linaro.org> * alpha-tdep.c (alpha_gdbarch_init): Don't call set_gdbarch_print_insn. * arc-tdep.c (arc_gdbarch_init): Likewise. * arch-utils.c: include dis-asm.h.

2017-05-24Refactor disassembler selectionYao Qi8-19/+57
Nowadays, opcodes/disassemble.c:disassembler selects the proper disassembler according to ABFD only. However, it actually selects disassemblers according to arch, mach, endianess, and abfd. This patch adds them to the parameters of disassembler, so that its caller can still select disassemblers in case that abfd is NULL (a typical case in GDB).

2017-05-23Cleanups to FreeBSD/mips native register operations.John Baldwin2-11/+21
Compare against the "raw" PC register number instead of the cooked register number when determining if a register was handled by PT_GETREGS. Previously the register fetch/store operations only tried PT_GETREGS to fetch any individual register. The result was that fetching or storing an individual register not covered by PT_GETREGS (such as floating point registers) did not work. While here, remove an early exit to simplify the code flow from the PT_GETREGS / PT_SETREGS case, and add a getfpregs_supplies similar to getregs_supplies to describe the registers supplied by PT_GETFPREGS and PT_SETFPREGS. gdb/ChangeLog: * mips-fbsd-nat.c (getregs_supplies): Fix upper bound comparison. (getpfpregs_supplies): New function. (mips_fbsd_fetch_inferior_registers): Remove early exit and use getfpregs_supplies. (mips_fbsd_store_inferior_registers): Likewise.

2017-05-22gdb: Document vMustReplyEmpty remote packetAndrew Burgess2-0/+17
Add mention of the vMustReplyEmpty to the remote serial protocol documentation. It is important that this packet be treated in the same fashion as any other unknown 'v' packet, and I have tried to reflect this in the description of the packet, it is not simply the case that we _must_ return the empty string for this packet. As the intention is that we should treat this packet as unknown then an argument could be made that we should not document it, however, for someone implementing a gdbserver from scratch, seeing an undocumented packet arrive from gdb is confusing, and will probably cause them to have to read the code in order to check how this packet should be handled, which is not ideal. gdb/doc/ChangeLog: * gdb.texinfo (Packets): Document vMustReplyEmpty packet.
