gdb: Remove a VEC from gdbsupport/btrace-common.h
Converts a VEC into a std::vector in gdbsupport/btrace-common.h. This commit just performs a mechanical conversion and doesn't do any refactoring. One consequence of this is that the std::vector must actually be a pointer to std::vector as it is placed within a union. It might be possible in future to refactor to a class hierarchy and remove the need for a union, but I'd rather have that be a separate change to make it easier to see the evolution of the code. gdb/ChangeLog: * btrace.c (btrace_compute_ftrace_bts): Update for std::vector, make accesses into the vector constant references. (btrace_add_pc): Update for std::vector. (btrace_stitch_bts): Likewise. (parse_xml_btrace_block): Likewise. (btrace_maint_update_packets): Likewise. (btrace_maint_print_packets): Likewise.

Remove Cell Broadband Engine debugging support
This patch implements removal of Cell/B.E. support, including - Support for the spu-*-* target - Support for native stand-alone SPU debugging - Support for integrated debugging of combined PPU/SPU applications - Remote debugging (gdbserver) support for all the above. The patch also removes the TARGET_OBJECT_SPU target object type, as this is available only on Cell/B.E. targets, including - Native Linux support - Core file support (including core file generation) - Remote target support, including removal of the qXfer:spu:read and qXfer:spu:write remote protocal packets and associated support in gdbserver. gdb/ChangeLog 2019-09-20 Ulrich Weigand <uweigand@de.ibm.com> * NEWS: Mention that Cell/B.E. debugging support was removed. * MAINTAINERS: Remove spu target. * config/djgpp/fnchange.lst: Remove entries for removed files. * Makefile.in (ALL_TARGET_OBS): Remove solib-spu.o, spu-multiarch.o, and spu-tdep.o.

Rename common to gdbsupport
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty. Tested by the buildbot. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

Use find_thread_in_random in select_event_lwp
I noticed that find_thread_in_random duplicates the code in find_thread_in_random, so this patch changes the latter to use the former. There are two other spots in gdb that do this, but to unify all of them would require switching some code from using the "iterate over" idiom to using iterators. Another possible improvement is that find_thread_in_random could be made single-pass using reservoir sampling. Tested by the buildbot. gdb/gdbserver/ChangeLog 2019-04-09 Tom Tromey <tromey@adacore.com> * linux-low.c (select_event_lwp): Use find_thread_in_random. |

Replace throw_exception with throw in some cases
This replaces throw_exception with "throw;" when possible. This was written by script. The rule that is followed is that uses of the form: catch (... &name) { ... throw_exception (name); } ... can be rewritten. This should always be safe, because exceptions are caught by const reference, and therefore can't be modified in the body of the catch. gdb/ChangeLog 2019-04-08 Tom Tromey <tom@tromey.com> * valops.c (value_rtti_indirect_type): Replace throw_exception with throw. * tracefile-tfile.c (tfile_target_open): Replace throw_exception with throw. * thread.c (thr_try_catch_cmd): Replace throw_exception with throw. * target.c (target_translate_tls_address): Replace throw_exception with throw. * stack.c (frame_apply_command_count): Replace throw_exception with throw. * solib-spu.c (append_ocl_sos): Replace throw_exception with throw. * s390-tdep.c (s390_frame_unwind_cache): Replace throw_exception with throw. * rs6000-tdep.c (rs6000_frame_cache) (rs6000_epilogue_frame_cache): Replace throw_exception with throw. * remote.c: Replace throw_exception with throw. * record-full.c (record_full_message, record_full_wait_1) (record_full_restore): Replace throw_exception with throw. * record-btrace.c: (get_thread_current_frame_id, record_btrace_start_replaying) (cmd_record_btrace_bts_start, cmd_record_btrace_pt_start) (cmd_record_btrace_start): Replace throw_exception with throw. * parse.c (parse_exp_in_context_1): Replace throw_exception with throw. * linux-nat.c (detach_one_lwp, linux_resume_one_lwp) (resume_stopped_resumed_lwps): Replace throw_exception with throw. * linespec.c: (find_linespec_symbols): Replace throw_exception with throw. * infrun.c (displaced_step_prepare, resume): Replace throw_exception with throw. * infcmd.c (post_create_inferior): Replace throw_exception with throw. * inf-loop.c (inferior_event_handler): Replace throw_exception with throw. * i386-tdep.c (i386_frame_cache, i386_epilogue_frame_cache) (i386_sigtramp_frame_cache): Replace throw_exception with throw. * frame.c (frame_unwind_pc, get_prev_frame_if_no_cycle) (get_prev_frame_always, get_frame_pc_if_available) (get_frame_address_in_block_if_available, get_frame_language): Replace throw_exception with throw. * frame-unwind.c (frame_unwind_try_unwinder): Replace throw_exception with throw. * eval.c (fetch_subexp_value, evaluate_var_value) (evaluate_funcall, evaluate_subexp_standard): Replace throw_exception with throw. * dwarf2loc.c (call_site_find_chain) (dwarf2_evaluate_loc_desc_full, dwarf2_locexpr_baton_eval): Replace throw_exception with throw. * dwarf2-frame.c (dwarf2_frame_cache): Replace throw_exception with throw. * darwin-nat.c (darwin_attach_pid): Replace throw_exception with throw. * cp-abi.c (baseclass_offset): Replace throw_exception with throw. * completer.c (complete_line_internal): Replace throw_exception with throw. * compile/compile-object-run.c (compile_object_run): Replace throw_exception with throw. * cli/cli-script.c (process_next_line): Replace throw_exception with throw. * btrace.c (btrace_compute_ftrace_pt, btrace_compute_ftrace) (btrace_enable, btrace_maint_update_pt_packets): Replace throw_exception with throw. * breakpoint.c (create_breakpoint, save_breakpoints): Replace throw_exception with throw. * break-catch-throw.c (re_set_exception_catchpoint): Replace throw_exception with throw. * amd64-tdep.c (amd64_frame_cache, amd64_sigtramp_frame_cache) (amd64_epilogue_frame_cache): Replace throw_exception with throw. * aarch64-tdep.c (aarch64_make_prologue_cache) (aarch64_make_stub_cache): Replace throw_exception with throw. gdb/gdbserver/ChangeLog 2019-04-08 Tom Tromey <tom@tromey.com> * linux-low.c (linux_detach_one_lwp): Replace throw_exception with throw.

Rename gdb exception types
This renames the gdb exception types. The old types were only needed due to the macros in common-exception.h that are now gone. The intermediate layer of gdb_exception_RETURN_MASK_ALL did not seem needed, so this patch removes it entirely. gdb/ChangeLog 2019-04-08 Tom Tromey <tom@tromey.com> * common/common-exceptions.h (gdb_exception_RETURN_MASK_ALL): Remove.

Use linux_get_auxv to get AT_PHDR in the PPC stub
This patch fixes a build error due to a call to ppc_get_auxv that was
left over after linux_get_hwcap and linux_get_hwcap2 were introduced

gdbserver: Ensure AT_HWCAP2 is defined
When using older compilers, AT_HWCAP2 may not be be defined. It is defined in elf/common.h, however including this in gdbserver/linux-low.c causes conflicts. Manually add the define if it does not exist. gdb/gdbserver/ChangeLog: * linux-low.c (AT_HWCAP2): Add define if not already included. |

AArch64: gdbserver: read pauth registers
Add the pauth registers to the regset lists. Add a new regset type OPTIONAL_REGS which allows for the regset read to fail. Once the read fails, it will not be checked again. This allows targets with optional features to keep a single static regset_info structure. gdb/ChangeLog: * arch/aarch64.h (AARCH64_PAUTH_REGS_SIZE): New define. gdb/gdbserver/ChangeLog: * linux-aarch64-low.c (aarch64_store_pauthregset): New function. * linux-low.c (regsets_store_inferior_registers): Allow optional reads to fail. * linux-low.h (enum regset_type): Add OPTIONAL_REGS. |

gdbserver: When attaching, add process before lwps
The recent BP/WP changes for AArch64 swapping the order in add_lwp() so that the process was added before the lwp. This was due to the lwp creation requiring the process data. This also needs changing in linux_attach(). Also add additional checks to make sure cannot attach to the same process twice. Add test case for this - do this by splitting attach.exp into distinct pass and error case sections. Fixes gdb.server/ext-attach.exp on Aarch64. gdb/gdbserver/ChangeLog: * linux-low.c (linux_attach): Add process before lwp. * server.c (attach_inferior): Check if already attached. gdb/testsuite/ChangeLog: * gdb.base/attach.exp: Add double attach test. |

This also needs changing in linux_attach(). Fixes gdb.server/ext-attach.exp on Aarch64. (This regression was hidden due to the racy nature of the gdb.server tests - now they are no longer racy it'll be easier to spot. Also checked X86). gdb/gdbserver/ChangeLog: 2019-01-25 Alan Hayward <alan.hayward@arm.com> * linux-low.c (linux_attach): Add process before lwp. |

Update copyright year range in all GDB files.
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files. |

AArch64: Racy: Don't set empty set of hardware BPs/WPs on new thread
On some heavily loaded AArch64 boxes, GDB will sometimes hang forever when the inferior creates a thread. This hang happens inside the kernel during the ptrace call to set hardware watchpoints or hardware breakpoints. Currently, GDB will always set hw wp/bp at the start of each thread even if there are none set in the process. This patch works around the issue by avoiding setting hw wp/bp if there are none set for the process. On an effected machine, this fix drastically reduces the racy nature of the gdb.threads test set. I ran the entire gdb test suite across all processors for 100 iterations, then ran the results through the racy tests script. Without the patch, 58 .exp files in gdb.threads were marked as racy. After the patch this reduced to the same ~14 tests as the non effected boxes. Clearly GDB will still be subject to hangs on an effect box if hw wp/bp's are used prior to creating inferior threads on a heavily loaded system. To enable this in gdbserver, the sequence in gdbserver add_lwp() is switched to the same as gdb order as gdb, to ensure the thread is registered before calling new_thread(). This allows aarch64_linux_new_thread() to read the ptid. gdb/ChangeLog: * nat/aarch64-linux-hw-point.c (aarch64_linux_any_set_debug_regs_state): New function. * nat/aarch64-linux-hw-point.h (aarch64_linux_any_set_debug_regs_state): New declaration. * nat/aarch64-linux.c (aarch64_linux_new_thread): Check if any BPs or WPs are set. gdb/gdbserver/ChangeLog: * linux-low.c (add_lwp): Switch ordering. |

Fix use-after-free in gdbserver
-fsanitize=address pointed out a use-after-free in gdbserver. In particular, handle_detach could reference "process" after it was deleted by detach_inferior. Avoiding this also necessitated changing target_ops::join to take a pid rather than a process_info*. Tested by the buildbot using a few of the gdbserver builders. gdb/gdbserver/ChangeLog 2018-11-29 Tom Tromey <tom@tromey.com> * win32-low.c (win32_join): Take pid, not process. * target.h (struct target_ops) <join>: Change argument type. (join_inferior): Change argument name. * spu-low.c (spu_join): Take pid, not process. * server.c (handle_detach): Preserve pid before destroying process. * lynx-low.c (lynx_join): Take pid, not process. * linux-low.c (linux_join): Take pid, not process. |

Warn if /proc is not accessible
There's a buildroot where I want to debug a binary, and I tried to connect to it from outside, but got very weird errors like architecture mismatch or protocol errors. At last, after switching on '--debug' for gdbserver I found a message 'Can't open /proc/pid/' message and suddenly found that I forgot to mount procfs in my buildroot. Make discovering the problem easier by making GDB / GDBserver warn (even without --debug) if /proc can not be accessed. Native debugging: (gdb) start Temporary breakpoint 1 at 0x400835: file test.c, line 10. Starting program: /tmp/test warning: /proc is not accessible.

Add xml_escape_text_append and use it
[This patch should go on top of "linux_qxfer_libraries_svr4: Use std::string", I should have sent them together as a series.] I noticed that linux_qxfer_libraries_svr4 used xml_escape_text, which returns an std::string. That string is then copied into a larger buffer. It would be more efficient if we had a version of xml_escape_text which appended to an existing string instead of returning a new one. This is what this patch does.

btrace, gdbserver: remove the to_supports_btrace target method
Remove the to_supports_btrace target method and instead rely on detecting errors when trying to enable recording. This will also provide a suitable error message explaining why recording is not possible. For remote debugging, gdbserver will now always advertise branch tracing related packets. When talking to an older GDB, this will cause GDB to try to enable branch tracing and gdbserver to report a suitable error message every time. An older gdbserver will not advertise branch tracing related packets if the one-time check failed, so a newer GDB with this patch will fail to enable branch tracing at remote_enable_btrace() rather than at btrace_enable(). The error message is the same in both cases so there should be no user-visible change. gdb/ * btrace.c (btrace_enable): Remove target_supports_btrace call. * nat/linux-btrace.c (perf_event_pt_event_type): Move. (kernel_supports_bts, kernel_supports_pt, linux_supports_bts) (linux_supports_pt, linux_supports_btrace): Remove. (linux_enable_bts): Call cpu_supports_bts. * nat/linux-btrace.h (linux_supports_btrace): Remove. * remote.c (remote_supports_btrace): Remove.

Make linux_ptrace_attach_fail_reason return an std::string
This patch makes linux_ptrace_attach_fail_reason and linux_ptrace_attach_fail_reason_string return std::string. It also replaces usages of struct buffer with std::string. This allows getting rid of a cleanup in in linux_ptrace_attach_fail_reason_string and simplifies the code in general. Something that looks odd to me is that in linux_ptrace_attach_fail_reason, if the two messages are appended, there is no separating space or \n, so the result won't be very nice. I left it as-is for now though. gdb/ChangeLog: * nat/linux-ptrace.h (linux_ptrace_attach_fail_reason): Return std::string. (linux_ptrace_attach_fail_reason_string): Likewise. * nat/linux-ptrace.c (linux_ptrace_attach_fail_reason): Likewise. (linux_ptrace_attach_fail_reason_string): Likewise. * linux-nat.c (attach_proc_task_lwp_callback): Adjust. gdb/gdbserver/ChangeLog: * linux-low.c (attach_proc_task_lwp_callback): Adjust to linux_ptrace_attach_fail_reason_string now returning an std::string. (linux_attach): Likewise. * thread-db.c (attach_thread): Likewise. |

Mark register unavailable when PTRACE_PEEKUSER fails
As described in PR 18749, GDB/GDBserver may get an error on accessing memory or register because the thread may disappear. However, some path doesn't expect the error. This patch fixes this problem by marking the register unavailable when PTRACE_PEEKUSER fails instead of throwing error. gdb/gdbserver: 2018-01-16 Yao Qi <yao.qi@linaro.org> PR gdb/18749 * linux-low.c (fetch_register): Call supply_register instead of error. |
