2019-07-10Don't include gdbarch.h from defs.hTom Tromey1-0/+1
I touched symtab.h and was surprised to see how many files were rebuilt. I looked into it a bit, and found that defs.h includes gdbarch.h, which in turn includes many things. gdbarch.h is only needed by a minority ofthe files in gdb, so this patch removes the include from defs.h and updates the fallout. I did "wc -l" on the files in build/gdb/.deps; this patch reduces the line count from 139935 to 137030; so there are definitely future build-time savings here. Note that while I configured with --enable-targets=all, it's possible that some *-nat.c file needs an update. I could not test all of these. The buildbot caught a few problems along these lines. gdb/ChangeLog 2019-07-10 Tom Tromey <tom@tromey.com> * defs.h: Don't include gdbarch.h. * aarch64-ravenscar-thread.c, aarch64-tdep.c, alpha-bsd-tdep.h, alpha-linux-tdep.c, alpha-mdebug-tdep.c, arch-utils.h, arm-tdep.h, ax-general.c, btrace.c, buildsym-legacy.c, buildsym.h, c-lang.c, cli/cli-decode.h, cli/cli-dump.c, cli/cli-script.h, cli/cli-style.h, coff-pe-read.h, compile/compile-c-support.c, compile/compile-cplus.h, compile/compile-loc2c.c, corefile.c, cp-valprint.c, cris-linux-tdep.c, ctf.c, d-lang.c, d-namespace.c, dcache.c, dicos-tdep.c, dictionary.c, disasm-selftests.c, dummy-frame.c, dummy-frame.h, dwarf2-frame-tailcall.c, dwarf2expr.c, expression.h, f-lang.c, frame-base.c, frame-unwind.c, frv-linux-tdep.c, gdbarch-selftests.c, gdbtypes.h, go-lang.c, hppa-nbsd-tdep.c, hppa-obsd-tdep.c, i386-dicos-tdep.c, i386-tdep.h, ia64-vms-tdep.c, interps.h, language.c, linux-record.c, location.h, m2-lang.c, m32r-linux-tdep.c, mem-break.c, memattr.c, mn10300-linux-tdep.c, nios2-linux-tdep.c, objfiles.h, opencl-lang.c, or1k-linux-tdep.c, p-lang.c, parser-defs.h, ppc-tdep.h, probe.h, python/py-record-btrace.c, record-btrace.c, record.h, regcache-dump.c, regcache.h, riscv-fbsd-tdep.c, riscv-linux-tdep.c, rust-exp.y, sh-linux-tdep.c, sh-nbsd-tdep.c, source-cache.c, sparc-nbsd-tdep.c, sparc-obsd-tdep.c, sparc-ravenscar-thread.c, sparc64-fbsd-tdep.c, std-regs.c, target-descriptions.h, target-float.c, tic6x-linux-tdep.c, tilegx-linux-tdep.c, top.c, tracefile.c, trad-frame.c, type-stack.h, ui-style.c, utils.c, utils.h, valarith.c, valprint.c, varobj.c, x86-tdep.c, xml-support.h, xtensa-linux-tdep.c, cli/cli-cmds.h: Update. * s390-linux-nat.c, procfs.c, inf-ptrace.c: Likewise.
2019-07-09Rename common to gdbsupportTom Tromey1-2/+2
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. *

2019-06-11Remove trailing newlines from help textTom Tromey1-5/+3
I noticed recently that some command had a trailing newline in its "help" output. So, I temporarily hacked cli-decode.c to print something when a new command was installed that had a trailing newline in its help message, and wrote this patch, which removes all the ones I could find this way. (There could still be a few more in *-nat files.) Tested on x86-64 Fedora 29. gdb/ChangeLog 2019-06-11 Tom Tromey <tromey@adacore.com> * infcall.c (_initialize_infcall): Remove trailing newline from help. * user-regs.c (_initialize_user_regs): Remove trailing newline from help. * typeprint.c (_initialize_typeprint): Remove trailing newline from help. * reverse.c (_initialize_reverse): Remove trailing newlines from help. * tracepoint.c (_initialize_tracepoint): Remove trailing newlines from help. * language.c (add_set_language_command): Remove trailing newline from help. * infcmd.c (_initialize_infcmd): Remove trailing newlines from help. * disasm.c (_initialize_disasm): Remove trailing newline from help. * top.c (init_main): Remove trailing newline from help. * interps.c (_initialize_interpreter): Remove trailing newline from help. * btrace.c (_initialize_btrace): Remove trailing newlines from help. * breakpoint.c (_initialize_breakpoint): Remove trailing newline from help. * python/python.c (_initialize_python): Remove trailing newline from help. * spu-tdep.c (_initialize_spu_tdep): Remove trailing newlines from help. * tui/tui-win.c (_initialize_tui_win): Remove trailing newlines from help.

2019-04-08Replace throw_exception with throw in some casesTom Tromey1-4/+4
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.

2019-03-13Change pid_to_str to return std::stringTom Tromey1-5/+5
Currently the target pid_to_str method returns a const char *, so many implementations have a static buffer that they update. This patch changes these methods to return a std::string instead. I think this is cleaner and avoids possible gotchas when calling pid_to_str on different ptids in a single statement. (Though no such calls exist currently.) This also updates various helper functions, and the gdbarch pid_to_str methods. I also made a best effort to fix all the callers, but I can't build some of the *-nat.c files. Tested by the buildbot. gdb/ChangeLog 2019-03-13 Tom Tromey <tromey@adacore.com> * i386-gnu-nat.c (i386_gnu_nat_target::fetch_registers) (i386_gnu_nat_target::store_registers): Update. * target-debug.h (target_debug_print_std_string): New macro. * x86-linux-nat.c (x86_linux_nat_target::enable_btrace): Update. * windows-tdep.c (display_one_tib): Update. * tui/tui-stack.c (tui_make_status_line): Update. * top.c (print_inferior_quit_action): Update. * thread.c (thr_try_catch_cmd): Update.

2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+1
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.
2018-11-22Per-inferior thread list, thread ranges/iterators, down with ALL_THREADS, etc.Pedro Alves1-3/+1
As preparation for multi-target, this patch makes each inferior have its own thread list. This isn't absolutely necessary for multi-target, but simplifies things. It originally stemmed from the desire to eliminate the init_thread_list calls sprinkled around, plus it makes it more efficient to iterate over threads of a given inferior (no need to always iterate over threads of all inferiors). We still need to iterate over threads of all inferiors in a number of places, which means we'd need adjust the ALL_THREADS / ALL_NON_EXITED_THREADS macros. However, naively tweaking those macros to have an extra for loop, like: #define ALL_THREADS (thr, inf) \ for (inf = inferior_list; inf; inf = inf->next) \ for (thr = inf->thread_list; thr; thr = thr->next) causes problems with code that does "break" or "continue" within the ALL_THREADS loop body. Plus, we need to declare the extra "inf" local variable in order to pass it as temporary variable to ALL_THREADS (etc.) It gets even trickier when we consider extending the macros to filter out threads matching a ptid_t and a target. The macros become tricker to read/write. Been there. An alternative (which was my next attempt), is to replace the ALL_THREADS etc. iteration style with for_each_all_threads, for_each_non_exited_threads, etc. functions which would take a callback as parameter, which would usually be passed a lambda. However, I did not find that satisfactory at all, because the resulting code ends up a little less natural / more noisy to read, write and debug/step-through (due to use of lambdas), and in many places where we use "continue;" to skip to the next thread now need to use "return;". (I ran into hard to debug bugs caused by a continue/return confusion.) I.e., before: ALL_NON_EXITED_THREADS (tp) { if (tp->not_what_I_want) continue; // do something } would turn into: for_each_non_exited_thread ([&] (thread_info *tp) { if (tp->not_what_I_want) return; // do something }); Lastly, the solution I settled with was to replace the ALL_THREADS / ALL_NON_EXITED_THREADS / ALL_INFERIORS macros with (C++20-like) ranges and iterators, such that you can instead naturaly iterate over threads/inferiors using range-for, like e.g,.: // all threads, including THREAD_EXITED threads. for (thread_info *tp : all_threads ()) { .... } // all non-exited threads. for (thread_info *tp : all_non_exited_threads ()) { .... } // all non-exited threads of INF inferior. for (thread_info *tp : inf->non_exited_threads ()) { .... } The all_non_exited_threads() function takes an optional filter ptid_t as parameter, which is quite convenient when we need to iterate over threads matching that filter. See e.g., how the set_executing/set_stop_requested/finish_thread_state etc. functions in thread.c end up being simplified. Most of the patch thus is about adding the infrustructure for allowing the above. Later on when we get to actual multi-target, these functions/ranges/iterators will gain a "target_ops *" parameter so that e.g., we can iterate over all threads of a given target that match a given filter ptid_t. The only entry points users needs to be aware of are the all_threads/all_non_exited_threads etc. functions seen above. Thus, those functions are declared in gdbthread.h/inferior.h. The actual iterators/ranges are mainly "internals" and thus are put out of view in the new thread-iter.h/thread-iter.c/inferior-iter.h files. That keeps the gdbthread.h/inferior.h headers quite a bit more readable. A common/safe-iterator.h header is added which adds a template that can be used to build "safe" iterators, which are forward iterators that can be used to replace the ALL_THREADS_SAFE macro and other instances of the same idiom in future. There's a little bit of shuffling of code between gdbthread.h/thread.c/inferior.h in the patch. That is necessary in order to avoid circular dependencies between the gdbthread.h/inferior.h headers. As for the init_thread_list calls sprinkled around, they're all eliminated by this patch, and a new, central call is added to inferior_appeared. Note how also related to that, there's a call to init_wait_for_inferior in remote.c that is eliminated. init_wait_for_inferior is currently responsible for discarding skipped inline frames, which had to be moved elsewhere. Given that nowadays we always have a thread even for single-threaded processes, the natural place is to delete a frame's inline frame info when we delete the thread. I.e., from clear_thread_inferior_resources. gdb/ChangeLog: 2018-11-22 Pedro Alves <palves@redhat.com> * Makefile.in (COMMON_SFILES): Add thread-iter.c. * breakpoint.c (breakpoints_should_be_inserted_now): Replace ALL_NON_EXITED_THREADS with all_non_exited_threads.

Some versions of _Unwind_RaiseException, e.g. on Fedora 28, use an indirect jump to return to the exception handler. This messes up the output of "record function-call-history /c" since the return is interpreted as cross-function goto. It had been detected by gdb.btrace/exception.exp. Add a heuristic for "_Unwind_*" functions to interpret an indirect jump that ends in one of our caller functions as return to the first instance of that function in our call stack. gdb/ * btrace.c (ftrace_update_function): Add indirect jump heuristic.

2018-06-21Use thread_info and inferior pointers more throughoutPedro Alves1-18/+12
This is more preparation bits for multi-target support. In a multi-target scenario, we need to address the case of different processes/threads running on different targets that happen to have the same PID/PTID. E.g., we can have both process 123 in target 1, and process 123 in target 2, while they're in reality different processes running on different machines. Or maybe we've loaded multiple instances of the same core file. Etc. To address this, in my WIP multi-target branch, threads and processes are uniquely identified by the (process_stratum target_ops *, ptid_t) and (process_stratum target_ops *, pid) tuples respectively. I.e., each process_stratum instance has its own thread/process number space. As you can imagine, that requires passing around target_ops * pointers in a number of functions where we're currently passing only a ptid_t or an int. E.g., when we look up a thread_info object by ptid_t in find_thread_ptid, the ptid_t alone isn't sufficient. In many cases though, we already have the thread_info or inferior pointer handy, but we "lose" it somewhere along the call stack, only to look it up again by ptid_t/pid. Since thread_info or inferior objects know their parent target, if we pass around thread_info or inferior pointers when possible, we avoid having to add extra target_ops parameters to many functions, and also, we eliminate a number of by ptid_t/int lookups. So that's what this patch does. In a bit more detail: - Changes a number of functions and methods to take a thread_info or inferior pointer instead of a ptid_t or int parameter. - Changes a number of structure fields from ptid_t/int to inferior or thread_info pointers. - Uses the inferior_thread() function whenever possible instead of inferior_ptid. - Uses thread_info pointers directly when possible instead of the is_running/is_stopped etc. routines that require a lookup. - A number of functions are eliminated along the way, such as: int valid_gdb_inferior_id (int num); int pid_to_gdb_inferior_id (int pid); int gdb_inferior_id_to_pid (int num); int in_inferior_list (int pid); - A few structures and places hold a thread_info pointer across inferior execution, so now they take a strong reference to the (refcounted) thread_info object to avoid the thread_info pointer getting stale. This is done in enable_thread_stack_temporaries and in the infcall.c code. - Related, there's a spot in infcall.c where using a RAII object to handle the refcount would be handy, so a gdb::ref_ptr specialization for thread_info is added (thread_info_ref, in gdbthread.h), along with a gdb_ref_ptr policy that works for all refcounted_object types (in common/refcounted-object.h). gdb/ChangeLog: 2018-06-21 Pedro Alves <palves@redhat.com> * ada-lang.h (ada_get_task_number): Take a thread_info pointer instead of a ptid_t.

2018-04-13btrace: set/show record btrace cpuMarkus Metzger1-23/+49
Add new set/show commands to set the processor that is used for enabling errata workarounds when decoding branch trace. The general format is "<vendor>:<identifier>" but we also allow two special values "auto" and "none". The default is "auto", which is the current behaviour of having GDB determine the processor on which the trace was recorded. If that cpu is not known to the trace decoder, e.g. when using an old decoder on a new system, decode may fail with "unknown cpu". In most cases it should suffice to 'downgrade' decode to assume an older cpu. Unfortunately, we can't do this automatically. The other special value, "none", disables errata workarounds. gdb/ * NEWS (New options): announce set/show record btrace cpu. * btrace.c: Include record-btrace.h.

2018-02-09btrace, gdbserver: remove the to_supports_btrace target methodMarkus Metzger1-3/+0
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.

2017-12-05Remove some unused variablesSimon Marchi1-4/+0
This patch removes some unused variables, found with -Wunused. I have not removed everything reported by -Wunused, because some expressions such as struct type *arg_type = check_typedef (value_type); in bfin-tdep.c could have an unexpected but important side-effect. I removed others that I considered more low-risk, such as: struct gdbarch *gdbarch = get_objfile_arch (objfile); I tested building with Python 2/Python 3/no Python, with/without expat, with/without libipt and with/without babeltrace. gdb/ChangeLog: * ada-lang.c (ada_collect_symbol_completion_matches): Remove unused variables.

2017-10-11Constify add_prefix_cmdTom Tromey1-5/+5
This changes add_prefix_cmd to accept a const-taking function as an argument; then fixes up all the callers. In a couple of spots I had to add a non-const overload of a function, because the function is passed to two different command-adding "constructors". These overloads are temporary; once constification is complete they can be removed. This patch also fixes a typo I happened to notice while constifying. Note that this touches a couple of files (gnu-nat.c and go32-nat.c) that I can't build. So, while I made a best-effort there, I am not certain they will still compile.

2017-08-18Remove save_inferior_ptidTom Tromey1-2/+2
This removes save_inferior_ptid, a cleanup function, in favor of scoped_restore. This also fixes a possible (it seems unlikely that it could happen in practice) memory leak -- save_inferior_ptid should have used make_cleanup_dtor, because it allocated memory. I tested this on the buildbot. However, there are two caveats to this. First, sometimes it seems I misread the results. Second, I think this patch touches some platforms that can't be tested by the buildbot. So, extra care seems warranted.

2017-05-31btrace: support decoder eventsMarkus Metzger1-41/+114

2017-05-30btrace: Replace struct btrace_function::segment.Tim Wiederhake1-20/+28
This used to hold a pair of pointers to the previous and next function segment that belong to this function call. Replace with a pair of indices into the vector of function segments.
2017-05-30btrace: Remove struct btrace_function::flow.Tim Wiederhake1-20/+24
This used to hold a pair of pointers to the previous and next function segment in execution flow order. It is no longer necessary as the previous and next function segments now are simply the previous and next elements in the vector of function segments.
2017-05-30btrace: Replace struct btrace_function::up.Tim Wiederhake1-52/+89
This used to hold a function segment pointer. Change it to hold an index into the vector of function segments instead.
2017-05-30btrace: Remove struct btrace_thread_info::{begin,end}.Tim Wiederhake1-101/+89
These are no longer needed and might hold invalid addresses once we change the vector of function segment pointers into a vector of function segment objects where a reallocation of the vector changes the address of its elements.

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 Wiederhake1-114/+84
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 Wiederhake1-0/+3
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 Wiederhake1-48/+53
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.

2017-05-02Python: Use correct ptid in btrace recordingTim Wiederhake1-1/+7
The user would always get the instruction_history and function_call_history objects of the current thread, not the thread for which the gdb.Record object was created. The attached testcase fails without this patch and passes with the patch.
2017-04-25Don't memset non-POD types: struct btrace_insnPedro Alves1-9/+14
struct btrace_insn is not a POD [1] so we shouldn't be using memset to initialize it [2]. Use list-initialization instead, wrapped in a "pt insn to btrace insn" function, which looks like just begging to be added next to the existing pt_reclassify_insn/pt_btrace_insn_flags functions. [1] - because its field "flags" is not POD, because enum_flags has a non-trivial default ctor. gdb/ChangeLog: 2017-04-25 Pedro Alves <palves@redhat.com> * btrace.c (pt_btrace_insn_flags): Change parameter type to reference. (pt_btrace_insn): New function. (ftrace_add_pt): Remove memset call and use pt_btrace_insn.
2017-02-14btrace: Use binary search to find instruction.Tim Wiederhake1-6/+39
Currently, btrace_find_insn_by_number will iterate over all function call segments to find the one that contains the needed instruction. This linear search is too slow for the upcoming Python bindings that will use this function to access instructions. This patch introduces a vector in struct btrace_thread_info that holds pointers to all recorded function segments and allows to use binary search. The proper solution is to turn the underlying tree into a vector of objects and use indices for access. This requires more work. A patch set is currently being worked on and will be published later.

2017-02-14btrace: preserve call stack on function switchMarkus Metzger1-2/+4
On 64-bit FC25, the _dl_runtime_resolve function uses a conditional branch to 'call' a particular variant optimized for that system: (gdb) disas _dl_runtime_resolve_avx_opt Dump of assembler code for function _dl_runtime_resolve_avx_opt: 0x00007ffff7deeb60 <+0>: push %rax 0x00007ffff7deeb61 <+1>: push %rcx 0x00007ffff7deeb62 <+2>: push %rdx 0x00007ffff7deeb63 <+3>: mov $0x1,%ecx 0x00007ffff7deeb68 <+8>: xgetbv 0x00007ffff7deeb6b <+11>: mov %eax,%r11d 0x00007ffff7deeb6e <+14>: pop %rdx 0x00007ffff7deeb6f <+15>: pop %rcx 0x00007ffff7deeb70 <+16>: pop %rax 0x00007ffff7deeb71 <+17>: and $0x4,%r11d 0x00007ffff7deeb75 <+21>: bnd je 0x7ffff7def4a0 <_dl_runtime_resolve_sse_vex> End of assembler dump. When computing the function-level trace, btrace treats this as a switch from _dl_runtime_resolve_avx_opt to _dl_runtime_resolve_sse_vex. We know that we switched functions but we can't really say in which caller/callee relationship those two functions are. In addition to preserving the indentaion level, also preserve the caller information. This is a heuristic since we don't really know. But at least in this case, this seems to be the right thing to do. This fixes a fail in gdb.btrace/rn-dl-bind.exp on 64-bit FC25. gdb/ * btrace.c (ftrace_new_switch): Preserve up link and flags.
2017-02-01btrace: allow recording to be started (and stopped) for running threadsMarkus Metzger1-4/+30
When recording is started for a running thread, GDB was able to start tracing but then failed to read registers to insert the initial entry for the current PC. We don't really need that initial entry if we don't know where exactly we started recording. Skip that step to allow recording to be started while threads are running. If we do run into errors, we need to undo the tracing enable to not leak this thread. The operation did not complete so our caller won't clean up this thread. For the BTRACE_FORMAT_PT btrace format, we don't need that initial entry since it will be recorded in the trace. We can omit the call to btrace_add_pc. gdb/ * btrace.c (btrace_enable): Do not call btrace_add_pc for BTRACE_FORMAT_PT or if can_access_registers_ptid returns false. (btrace_fetch): Assert can_access_registers_ptid. * record-btrace.c (require_btrace_thread, record_btrace_info): Call validate_registers_access. testsuite/ * gdb.btrace/enable-running.c: New. * gdb.btrace/enable-running.exp: New.
