2020-01-13gdb: add back declarations for _initialize functionsSimon Marchi1-1/+2
I'd like to enable the -Wmissing-declarations warning. However, it warns for every _initialize function, for example: CXX dcache.o /home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’: /home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations] _initialize_dcache (void) ^~~~~~~~~~~~~~~~~~ The only practical way forward I found is to add back the declarations, which were removed by this commit: commit 481695ed5f6e0a8a9c9c50bfac1cdd2b3151e6c9 Author: John Baldwin <jhb@FreeBSD.org> Date: Sat Sep 9 11:02:37 2017 -0700 Remove unnecessary function prototypes. I don't think it's a big problem to have the declarations for these functions, but if anybody has a better solution for this, I'll be happy to use it. gdb/ChangeLog: * aarch64-fbsd-nat.c

2020-01-10Multi-target supportPedro Alves1-16/+17
This commit adds multi-target support to GDB. What this means is that with this commit, GDB can now be connected to different targets at the same time. E.g., you can debug a live native process and a core dump at the same time, connect to multiple gdbservers, etc. Actually, the word "target" is overloaded in gdb. We already have a target stack, with pushes several target_ops instances on top of one another. We also have "info target" already, which means something completely different to what this patch does. So from here on, I'll be using the "target connections" term, to mean an open process_stratum target, pushed on a target stack. This patch makes gdb have multiple target stacks, and multiple process_stratum targets open simultaneously. The user-visible changes / commands will also use this terminology, but of course it's all open to debate. User-interface-wise, not that much changes. The main difference is that each inferior may have its own target connection. A target connection (e.g., a target extended-remote connection) may support debugging multiple processes, just as before. Say you're debugging against gdbserver in extended-remote mode, and you do "add-inferior" to prepare to spawn a new process, like: (gdb) target extended-remote :9999 ... (gdb) start ... (gdb) add-inferior Added inferior 2 (gdb) inferior 2 [Switching to inferior 2 [<null>] (<noexec>)] (gdb) file a.out ... (gdb) start ... At this point, you have two inferiors connected to the same gdbserver. With this commit, GDB will maintain a target stack per inferior, instead of a global target stack. To preserve the behavior above, by default, "add-inferior" makes the new inferior inherit a copy of the target stack of the current inferior. Same across a fork - the child inherits a copy of the target stack of the parent. While the target stacks are copied, the targets themselves are not. Instead, target_ops is made a refcounted_object, which means that target_ops instances are refcounted, which each inferior counting for a reference. What if you want to create an inferior and connect it to some _other_ target? For that, this commit introduces a new "add-inferior -no-connection" option that makes the new inferior not share the current inferior's target. So you could do: (gdb) target extended-remote :9999 Remote debugging using :9999 ... (gdb) add-inferior -no-connection [New inferior 2] Added inferior 2 (gdb) inferior 2 [Switching to inferior 2 [<null>] (<noexec>)] (gdb) info inferiors Num Description Executable 1 process 18401 target:/home/pedro/tmp/main * 2 <null> (gdb) tar extended-remote :10000 Remote debugging using :10000 ... (gdb) info inferiors Num Description Executable 1 process 18401 target:/home/pedro/tmp/main * 2 process 18450 target:/home/pedro/tmp/main (gdb) A following patch will extended "info inferiors" to include a column indicating which connection an inferior is bound to, along with a couple other UI tweaks. Other than that, debugging is the same as before. Users interact with inferiors and threads as before. The only difference is that inferiors may be bound to processes running in different machines. That's pretty much all there is to it in terms of noticeable UI changes. On to implementation. Since we can be connected to different systems at the same time, a ptid_t is no longer a unique identifier. Instead a thread can be identified by a pair of ptid_t and 'process_stratum_target *', the later being the instance of the process_stratum target that owns the process/thread. Note that process_stratum_target inherits from target_ops, and all process_stratum targets inherit from process_stratum_target. In earlier patches, many places in gdb were converted to refer to threads by thread_info pointer instead of ptid_t, but there are still places in gdb where we start with a pid/tid and need to find the corresponding inferior or thread_info objects. So you'll see in the patch many places adding a process_stratum_target parameter to functions that used to take only a ptid_t. Since each inferior has its own target stack now, we can always find the process_stratum target for an inferior. That is done via a inf->process_target() convenience method. Since each inferior has its own target stack, we need to handle the "beneath" calls when servicing target calls. The solution I settled with is just to make sure to switch the current inferior to the inferior you want before making a target call. Not relying on global context is just not feasible in current GDB. Fortunately, there aren't that many places that need to do that, because generally most code that calls target methods already has the current context pointing to the right inferior/thread. Note, to emphasize -- there's no method to "switch to this target stack". Instead, you switch the current inferior, and that implicitly switches the target stack. In some spots, we need to iterate over all inferiors so that we reach all target stacks. Native targets are still singletons. There's always only a single instance of such targets. Remote targets however, we'll have one instance per remote connection. The exec target is still a singleton. There's only one instance. I did not see the point of instanciating more than one exec_target object. After vfork, we need to make sure to push the exec target on the new inferior. See exec_on_vfork. For type safety, functions that need a {target, ptid} pair to identify a thread, take a process_stratum_target pointer for target parameter instead of target_ops *. Some shared code in gdb/nat/ also need to gain a target pointer parameter. This poses an issue, since gdbserver doesn't have process_stratum_target, only target_ops. To fix this, this commit renames gdbserver's target_ops to process_stratum_target. I think this makes sense. There's no concept of target stack in gdbserver, and gdbserver's target_ops really implements a process_stratum-like target. The thread and inferior iterator functions also gain process_stratum_target parameters. These are used to be able to iterate over threads and inferiors of a given target. Following usual conventions, if the target pointer is null, then we iterate over threads and inferiors of all targets. I tried converting "add-inferior" to the gdb::option framework, as a preparatory patch, but that stumbled on the fact that gdb::option does not support file options yet, for "add-inferior -exec". I have a WIP patchset that adds that, but it's not a trivial patch, mainly due to need to integrate readline's filename completion, so I deferred that to some other time. In infrun.c/infcmd.c, the main change is that we need to poll events out of all targets. See do_target_wait. Right after collecting an event, we switch the current inferior to an inferior bound to the target that reported the event, so that target methods can be used while handling the event. This makes most of the code transparent to multi-targets. See fetch_inferior_event. infrun.c:stop_all_threads is interesting -- in this function we need to stop all threads of all targets. What the function does is send an asynchronous stop request to all threads, and then synchronously waits for events, with target_wait, rinse repeat, until all it finds are stopped threads. Now that we have multiple targets, it's not efficient to synchronously block in target_wait waiting for events out of one target. Instead, we implement a mini event loop, with interruptible_select, select'ing on one file descriptor per target. For this to work, we need to be able to ask the target for a waitable file descriptor. Such file descriptors already exist, they are the descriptors registered in the main event loop with add_file_handler, inside the target_async implementations. This commit adds a new target_async_wait_fd target method that just returns the file descriptor in question. See wait_one / stop_all_threads in infrun.c. The 'threads_executing' global is made a per-target variable. Since it is only relevant to process_stratum_target targets, this is where it is put, instead of in target_ops. You'll notice that remote.c includes some FIXME notes. These refer to the fact that the global arrays that hold data for the remote packets supported are still globals. For example, if we connect to two different servers/stubs, then each might support different remote protocol features. They might even be different architectures, like e.g., one ARM baremetal stub, and a x86 gdbserver, to debug a host/controller scenario as a single program. That isn't going to work correctly today, because of said globals. I'm leaving fixing that for another pass, since it does not appear to be trivial, and I'd rather land the base work first. It's already useful to be able to debug multiple instances of the same server (e.g., a distributed cluster, where you have full control over the servers installed), so I think as is it's already reasonable incremental progress. Current limitations: - You can only resume more that one target at the same time if all targets support asynchronous debugging, and support non-stop mode. It should be possible to support mixed all-stop + non-stop backends, but that is left for another time. This means that currently in order to do multi-target with gdbserver you need to issue "maint set target-non-stop on". I would like to make that mode be the default, but we're not there yet. Note that I'm talking about how the target backend works, only. User-visible all-stop mode works just fine. - As explained above, connecting to different remote servers at the same time is likely to produce bad results if they don't support the exact set of RSP features.

2019-07-15Add include of gdbarch.h.John Baldwin1-0/+1
gdb/ChangeLog: * fbsd-nat.c: Include gdbarch.h.
2019-07-09Rename common to gdbsupportTom Tromey1-3/+3
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. *

2019-04-06Revert the header-sorting patchTom Tromey1-20/+16
Andreas Schwab and John Baldwin pointed out some bugs in the header sorting patch; and I noticed that the output was not correct when limited to a subset of files (a bug in my script). So, I'm reverting the patch. I may try again after fixing the issues pointed out. gdb/ChangeLog 2019-04-05 Tom Tromey <tom@tromey.com> Revert the header-sorting patch. * ft32-tdep.c: Revert. * frv-tdep.c: Revert. * frv-linux-tdep.c: Revert. * frame.c: Revert. * frame-unwind.c: Revert. * frame-base.c: Revert. * fork-child.c: Revert. * findvar.c: Revert. * findcmd.c: Revert. * filesystem.c: Revert. * filename-seen-cache.h: Revert. * filename-seen-cache.c: Revert. * fbsd-tdep.c: Revert. * fbsd-nat.h: Revert. * fbsd-nat.c: Revert. * f-valprint.c: Revert. * f-typeprint.c: Revert. * f-lang.c: Revert. * extension.h: Revert. * extension.c: Revert. * extension-priv.h: Revert. * expprint.c: Revert. * exec.h: Revert. * exec.c: Revert. * exceptions.c: Revert. * event-top.c: Revert. * event-loop.c: Revert. * eval.c: Revert. * elfread.c: Revert. * dwarf2read.h: Revert. * dwarf2read.c: Revert. * dwarf2loc.c: Revert. * dwarf2expr.h: Revert. * dwarf2expr.c: Revert. * dwarf2-frame.c: Revert. * dwarf2-frame-tailcall.c: Revert. * dwarf-index-write.h: Revert. * dwarf-index-write.c: Revert. * dwarf-index-common.c: Revert. * dwarf-index-cache.h: Revert. * dwarf-index-cache.c: Revert. * dummy-frame.c: Revert. * dtrace-probe.c: Revert. * disasm.h: Revert. * disasm.c: Revert. * disasm-selftests.c: Revert. * dictionary.c: Revert. * dicos-tdep.c: Revert. * demangle.c: Revert. * dcache.h: Revert. * dcache.c: Revert. * darwin-nat.h: Revert. * darwin-nat.c: Revert. * darwin-nat-info.c: Revert. * d-valprint.c: Revert. * d-namespace.c: Revert. * d-lang.c: Revert. * ctf.c: Revert. * csky-tdep.c: Revert. * csky-linux-tdep.c: Revert. * cris-tdep.c: Revert. * cris-linux-tdep.c: Revert. * cp-valprint.c: Revert. * cp-support.c: Revert. * cp-namespace.c: Revert. * cp-abi.c: Revert. * corelow.c: Revert. * corefile.c: Revert. * continuations.c: Revert. * completer.h: Revert. * completer.c: Revert. * complaints.c: Revert. * coffread.c: Revert. * coff-pe-read.c: Revert. * cli-out.h: Revert. * cli-out.c: Revert. * charset.c: Revert. * c-varobj.c: Revert. * c-valprint.c: Revert. * c-typeprint.c: Revert. * c-lang.c: Revert. * buildsym.c: Revert. * buildsym-legacy.c: Revert. * build-id.h: Revert. * build-id.c: Revert. * btrace.c: Revert. * bsd-uthread.c: Revert. * breakpoint.h: Revert. * breakpoint.c: Revert. * break-catch-throw.c: Revert. * break-catch-syscall.c: Revert. * break-catch-sig.c: Revert. * blockframe.c: Revert. * block.c: Revert. * bfin-tdep.c: Revert. * bfin-linux-tdep.c: Revert. * bfd-target.c: Revert. * bcache.c: Revert. * ax-general.c: Revert. * ax-gdb.h: Revert. * ax-gdb.c: Revert. * avr-tdep.c: Revert. * auxv.c: Revert. * auto-load.c: Revert. * arm-wince-tdep.c: Revert. * arm-tdep.c: Revert. * arm-symbian-tdep.c: Revert. * arm-pikeos-tdep.c: Revert. * arm-obsd-tdep.c: Revert. * arm-nbsd-tdep.c: Revert. * arm-nbsd-nat.c: Revert. * arm-linux-tdep.c: Revert. * arm-linux-nat.c: Revert. * arm-fbsd-tdep.c: Revert. * arm-fbsd-nat.c: Revert. * arm-bsd-tdep.c: Revert. * arch-utils.c: Revert. * arc-tdep.c: Revert. * arc-newlib-tdep.c: Revert. * annotate.h: Revert. * annotate.c: Revert. * amd64-windows-tdep.c: Revert. * amd64-windows-nat.c: Revert. * amd64-tdep.c: Revert. * amd64-sol2-tdep.c: Revert. * amd64-obsd-tdep.c: Revert. * amd64-obsd-nat.c: Revert. * amd64-nbsd-tdep.c: Revert. * amd64-nbsd-nat.c: Revert. * amd64-nat.c: Revert. * amd64-linux-tdep.c: Revert. * amd64-linux-nat.c: Revert. * amd64-fbsd-tdep.c: Revert. * amd64-fbsd-nat.c: Revert. * amd64-dicos-tdep.c: Revert. * amd64-darwin-tdep.c: Revert. * amd64-bsd-nat.c: Revert. * alpha-tdep.c: Revert. * alpha-obsd-tdep.c: Revert. * alpha-nbsd-tdep.c: Revert. * alpha-mdebug-tdep.c: Revert. * alpha-linux-tdep.c: Revert. * alpha-linux-nat.c: Revert. * alpha-bsd-tdep.c: Revert. * alpha-bsd-nat.c: Revert. * aix-thread.c: Revert. * agent.c: Revert. * addrmap.c: Revert. * ada-varobj.c: Revert. * ada-valprint.c: Revert. * ada-typeprint.c: Revert. * ada-tasks.c: Revert. * ada-lang.c: Revert. * aarch64-tdep.c: Revert. * aarch64-ravenscar-thread.c: Revert. * aarch64-newlib-tdep.c: Revert. * aarch64-linux-tdep.c: Revert. * aarch64-linux-nat.c: Revert. * aarch64-fbsd-tdep.c: Revert. * aarch64-fbsd-nat.c: Revert. * aarch32-linux-nat.c: Revert.

2019-03-13Change pid_to_str to return std::stringTom Tromey1-8/+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.

2019-02-06Fix 'info proc cmdline' for native FreeBSD processes.John Baldwin1-0/+7
The kern.proc.args.<pid> sysctl returns the argv array as a packed array of arguments, each null terminated. To construct a complete command line, the arguments must be joined with spaces by converting the intermediate nul characters to spaces. Previously only the first argument was shown in cmdline output. Now, all arguments are shown. gdb/ChangeLog: * fbsd-nat.c (fbsd_fetch_cmdline): Join arguments with spaces.

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.
2018-12-21Workaround a FreeBSD kernel bug resulting in spurious SIGTRAP events.John Baldwin1-3/+9
The ptrace command PT_LWPINFO to request detailed information about a stopped thread can return stale signal information from an earlier stop. Events which are reporting an intercepted signal will always report the correct information, but signal stops for some other events such as system call enter/exit events might include stale siginfo from an earlier signal. In particular, if a thread reports a system call entry or exit event after previously reporting a single-step or breakpoint event via SIGTRAP, fbsd_handle_debug_trap believed the system call event was the previous event and claimed it resulting in a spurious SIGTRAP event. True breakpoint and single-step events will never report another event in the pl_flags member of struct ptrace_lwpinfo. Use this to detect stale siginfo by requiring pl_flags to have only the PL_FLAG_SI flag and no other flags before treating a SIGTRAP as a single-step or breakpoint trap. gdb/ChangeLog: * fbsd-nat.c (fbsd_handle_debug_trap): Require pl.pl_flags to equal PL_FLAG_SI. (fbsd_nat_target::stopped_by_sw_breakpoint): Likewise.
2018-11-30Update the conditionals in fbsd-nat.h so they are always honored.John Baldwin1-4/+15
Not all of the architecture-specific FreeBSD target files were including the right headers to enable conditionals in fbsd-nat.h after the C++ target conversion. As a result, certain operations like 'info auxv' and 'p $_siginfo' were not working for some native targets (noticed on RISC-V). Fix this in a couple of ways: 1) Declare fbsd_nat_target::xfer_partial unconditionally and only use conditionals in the function body for individual target objects. Originally this function was only used to read the ELF auxiliary vector, so the entire function was conditional on a macro required for that object (KERN_AUXV_PROC). However, xfer_partial has since grown support for additional objects. Making the function unconditional avoids needing to add the right header to fbsd-nat.h and allows each target object to use independent requirements. This did require using a more explicit conditional test for the $_siginfo support. Removing the "outer" KERN_PROC_AUXV test enabled $_siginfo for all kernels with PT_LWPINFO, but some older kernels (FreeBSD 6.0) exposed PT_LWPINFO with a different siginfo format. Instead use an explicit test for when the current siginfo format was adopted (shipped in FreeBSD 7.0). This actually enables $_siginfo on a wider range of kernels as KERN_PROC_AUXV wasn't introduced until FreeBSD 9.1/10.0. 2) Include <sys/proc.h> in fbsd-nat.h for the definition of TDP_RFPPWAIT that governs support for fork following. gdb/ChangeLog: * fbsd-nat.c [__FreeBSD_version >= 700009] (USE_SIGINFO): Macro defined. (union sigval32, struct siginfo32, fbsd_siginfo_size) (fbsd_convert_siginfo): Make conditional on USE_SIGINFO instead of KERN_PROC_AUXV and PT_LWPINFO. (fbsd_nat_target::xfer_partial): Define method unconditionally. Make TARGET_OBJECT_SIGNAL_INFO conditional on USE_SIGINFO. Make TARGET_OBJECT_AUXV conditional on KERN_PROC_AUXV. Make TARGET_OBJECT_FREEBSD_VMMAP and TARGET_OBJECT_FREEBSD_PS_STRINGS conditional on KERN_PROC_VMMAP and KERN_PROC_PS_STRINGS. * fbsd-nat.h: Include <sys/proc.h>. (fbsd_nat_target::xfer_partial): Declare method unconditionally.
2018-11-22Per-inferior thread list, thread ranges/iterators, down with ALL_THREADS, etc.Pedro Alves1-15/+6
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.

2018-05-03Convert struct target_ops to C++Pedro Alves1-159/+75
I.e., use C++ virtual methods and inheritance instead of tables of function pointers. Unfortunately, there's no way to do a smooth transition. ALL native targets in the tree must be converted at the same time. I've tested all I could with cross compilers and with help from GCC compile farm, but naturally I haven't been able to test many of the ports. Still, I made a best effort to port everything over, and while I expect some build problems due to typos and such, which should be trivial to fix, I don't expect any design problems. * Implementation notes: - The flattened current_target is gone. References to current_target or current_target.beneath are replaced with references to target_stack (the top of the stack) directly. - To keep "set debug target" working, this adds a new debug_stratum layer that sits on top of the stack, prints the debug, and delegates to the target beneath. In addition, this makes the shortname and longname properties of target_ops be virtual methods instead of data fields, and makes the debug target defer those to the target beneath. This is so that debug code sprinkled around that does "if (debugtarget) ..." can transparently print the name of the target beneath. A patch later in the series actually splits out the shortname/longname methods to a separate structure, but I preferred to keep that chance separate as it is associated with changing a bit the design of how targets are registered and open. - Since you can't check whether a C++ virtual method is overridden, the old method of checking whether a target_ops implements a method by comparing the function pointer must be replaced with something else. Some cases are fixed by adding a parallel "can_do_foo" target_ops methods. E.g.,: + for (t = target_stack; t != NULL; t = t->beneath) { - if (t->to_create_inferior != NULL) + if (t->can_create_inferior ()) break; } Others are fixed by changing void return type to bool or int return type, and have the default implementation return false or -1, to indicate lack of support. - make-target-delegates was adjusted to generate C++ classes and methods. It needed tweaks to grok "virtual" in front of the target method name, and for the fact that methods are no longer function pointers. (In particular, the current code parsing the return type was simple because it could simply parse up until the '(' in '(*to_foo)'. It now generates a couple C++ classes that inherit target_ops: dummy_target and debug_target. Since we need to generate the class declarations as well, i.e., we need to emit methods twice, we now generate the code in two passes. - The core_target global is renamed to avoid conflict with the "core_target" class. - ctf/tfile targets init_tracefile_ops is replaced by a base class that is inherited by both ctf and tfile. - bsd-uthread The bsd_uthread_ops_hack hack is gone. It's not needed because nothing was extending a target created by bsd_uthread_target. - remote/extended-remote targets This is a first pass, just enough to C++ify target_ops. A later pass will convert more free functions to methods, and make remote_state be truly per remote instance, allowing multiple simultaneous instances of remote targets. - inf-child/"native" is converted to an actual base class (inf_child_target), that is inherited by all native targets. - GNU/Linux The old weird double-target linux_ops mechanism in linux-nat.c, is gone, replaced by adding a few virtual methods to linux-nat.h's target_ops, called low_XXX, that the concrete linux-nat implementations override. Sort of like gdbserver's linux_target_ops, but simpler, for requiring only one target_ops-like hierarchy, which spares implementing the same method twice when we need to forward the method to a low implementation. The low target simply reimplements the target_ops method directly in that case. There are a few remaining linux-nat.c hooks that would be better converted to low_ methods like above too. E.g.: linux_nat_set_new_thread (t, x86_linux_new_thread); linux_nat_set_new_fork (t, x86_linux_new_fork); linux_nat_set_forget_process That'll be done in a follow up patch. - We can no longer use functions like x86_use_watchpoints to install custom methods on an arbitrary base target. The patch replaces instances of such a pattern with template mixins. For example memory_breakpoint_target defined in target.h, or x86_nat_target in x86-nat.h. - linux_trad_target, MIPS and Alpha GNU/Linux The code in the new linux-nat-trad.h/c files which was split off of inf-ptrace.h/c recently, is converted to a C++ base class, and used by the MIPS and Alpha GNU/Linux ports. - BSD targets The $architecture x NetBSD/OpenBSD/FreeBSD support matrix complicates things a bit. There's common BSD target code, and there's common architecture-specific code shared between the different BSDs. Currently, all that is stiched together to form a final target, via the i386bsd_target, x86bsd_target, fbsd_nat_add_target functions etc. This introduces new fbsd_nat_target, obsd_nat_target and nbsd_nat_target classes that serve as base/prototype target for the corresponding BSD variant. And introduces generic i386/AMD64 BSD targets, to be used as template mixin to build a final target. Similarly, a generic SPARC target is added, used by both BSD and Linux ports. - bsd_kvm_add_target, BSD libkvm target I considered making bsd_kvm_supply_pcb a virtual method, and then have each port inherit bsd_kvm_target and override that method, but that was resulting in lots of unjustified churn, so I left the function pointer mechanism alone. gdb/ChangeLog: 2018-05-02 Pedro Alves <palves@redhat.com> John Baldwin <jhb@freebsd.org> * target.h (enum strata) <debug_stratum>: New.

2018-03-03Use signal information to determine SIGTRAP type for FreeBSD.John Baldwin1-0/+107
Use the signal code from siginfo_t to distinguish SIGTRAP events due to trace traps (TRAP_TRACE) and software breakpoints (TRAP_BRKPT). For software breakpoints, adjust the PC when the event is reported as part of the API when supplying "stopped_by_sw_breakpoint". Currently FreeBSD only supports hardware watchpoints and breakpoints on x86 which are reported as trace traps. Signal information is not used on MIPS and sparc64 kernels which do not reliably report TRAP_BRKPT for software breakpoints. gdb/ChangeLog: * fbsd-nat.c: Include "inf-ptrace.h". (USE_SIGTRAP_SIGINFO): Conditionally define. [USE_SIGTRAP_SIGINFO] (fbsd_handle_debug_trap): New function. (fbsd_wait) [USE_SIGTRAP_SIGINFO]: Call "fbsd_handle_debug_trap".

2018-02-27Workaround a FreeBSD ptrace() bug with clearing thread events.John Baldwin1-0/+32
When multiple threads within a process wish to report STOPPED events from wait(), the kernel picks one thread event as the thread event to report. The chosen thread event is retrieved via PT_LWPINFO by passing the process ID as the request pid. If multiple events are pending, then the subsequent wait() after resuming a process will report another STOPPED event after resuming the process to handle the next thread event and so on. A single thread event is cleared as a side effect of resuming the process with PT_CONTINUE, PT_STEP, etc. In older kernels, however, the request pid was used to select which thread's event was cleared rather than always clearing the event that was just reported. To avoid clearing the event of the wrong LWP, always pass the process ID instead of an LWP ID to PT_CONTINUE or PT_SYSCALL. In the case of stepping, the process ID cannot be used with PT_STEP since it would step the thread that reported an event which may not be the thread indicated by PTID. For stepping, use PT_SETSTEP to enable stepping on the desired thread before resuming the process via PT_CONTINUE instead of using PT_STEP. This manifested as a failure in the gdb.threads/continue-pending-status.exp test. Specifically, if thread 2 reported a breakpoint and the test thus switched to thread 3 before continuing, thread 3's event (if any) was discarded and thread 2's breakpoint remained pending and was reported a second time as a duplicate event. As a result, the PC was decremented twice for the same breakpoint resulting in an illegal instruction fault on x86. gdb/ChangeLog: * fbsd-nat.c (fbsd_resume): Use PT_SETSTEP for stepping and a wildcard process pid for super_resume for kernels with a specific bug.
2018-01-09Support 'info proc' for native FreeBSD processes.John Baldwin1-26/+339
- Command line arguments are fetched via the kern.proc.args.<pid> sysctl. - The 'cwd' and 'exe' values are obtained from the per-process file descriptor table returned by kinfo_getfile() from libutil. - 'mappings' is implemented by walking the array of VM map entries returned by kinfo_getvmmap() from libutil. - 'status' output is generated by outputting fields from the structure returned by the kern.proc.pid.<pid> sysctl. - 'stat' is aliased to 'status'. gdb/ChangeLog: * configure.ac: Check for kinfo_getfile in libutil. * configure: Regenerate. * config.in: Regenerate. * fbsd-nat.c: Include "fbsd-tdep.h". (fbsd_fetch_cmdline): New. (fbsd_fetch_kinfo_proc): Move earlier and change to return a bool rather than calling error. (fbsd_info_proc): New. (fbsd_thread_name): Report error if fbsd_fetch_kinfo_proc fails. (fbsd_wait): Report warning if fbsd_fetch_kinfo_proc fails. (fbsd_nat_add_target): Set "to_info_proc" to "fbsd_info_proc".
2018-01-09Use gdb::unique_xmalloc_ptr<> instead of a deleter that invokes free().John Baldwin1-9/+1
Since xfree() always wraps free(), it is safe to use the xfree deleter for buffers allocated by library routines such as kinfo_getvmmap() that must be released via free(). gdb/ChangeLog: * fbsd-nat.c (struct free_deleter): Remove. (fbsd_find_memory_regions): Use gdb::unique_xmalloc_ptr<>.
2018-01-09Don't return stale data from fbsd_pid_to_exec_file for kernel processes.John Baldwin1-1/+4
For processes without an associated executable (such as kernel processes), the kern.proc.pathname.<pid> system control node returns a length of zero without modifying the user's buffer. Detect this case and return NULL rather than the previous contents of the static buffer 'buf'. gdb/ChangeLog: * fbsd-nat.c (fbsd_pid_to_exec_file) [KERN_PROC_PATHNAME]: Return NULL for an empty pathname.

gdb/ChangeLog: Update copyright year range in all GDB files
2017-12-06target_set_syscall_catchpoint, use gdb::array_view and boolPedro Alves1-2/+3
I noticed that we're passing down a data/size pair to target_ops::to_set_syscall_catchpoint. This commit makes use of gdb::array_view instead. While at it, use bool where appropriate as well. gdb/ChangeLog: * break-catch-syscall.c (insert_catch_syscall) (remove_catch_syscall): Adjust to pass reference to inf_data->syscalls_counts directly via gdb::array_view. * fbsd-nat.c (fbsd_set_syscall_catchpoint): Adjust to use bool and gdb::array_view. * linux-nat.c (linux_child_set_syscall_catchpoint): Likewise. * remote.c (remote_set_syscall_catchpoint): Likewise. * target-debug.h (target_debug_print_bool): New. (define target_debug_print_gdb_array_view_const_int): New. * target-delegates.c: Regenerate. * target.h (target_ops) <to_set_syscall_catchpoint>: Use gdb::array_view and bool. (target_set_syscall_catchpoint): Likewise.
2017-10-09Use gdbarch_long_bit to determine layout of FreeBSD siginfo_t.John Baldwin1-2/+2
FreeBSD architectures are either ILP32 or LP64 resulting in two different layouts for siginfo_t. Previously, the 'bits_per_word' member of bfd_arch_info was used to determine the layout to use for a given FreeBSD architecture. However, mipsn32 architectures inherit from a 64-bit mips architecture where bits_per_word is 64. As a result, $_siginfo was not properly extracted from FreeBSD/mipsn32 core dumps. Fix this by using gdbarch_long_bit instead of 'bits_per_word' to determine if a FreeBSD architecture is ILP32 or LP64. gdb/ChangeLog: * fbsd-nat.c (fbsd_siginfo_size): Use gdbarch_long_bit. (fbsd_convert_siginfo): Likewise. * fbsd-tdep.c (fbsd_core_xfer_siginfo): Likewise.

2017-08-21Use an array type (lwpid_t[]) for the array of lwp IDs.John Baldwin1-5/+4
gdb/ChangeLog: * fbsd-nat.c (fbsd_add_threads): Use array type for `lwps'.
2017-08-15Fix compile on big-endian platforms in siginfo_t converter.John Baldwin1-1/+1
gdb/ChangeLog: * fbsd-nat.c (fbsd_convert_siginfo): Fix compile on big-endian platforms.
2017-08-09Replace home-grown linked-lists in FreeBSD's native target with STL lists.John Baldwin1-50/+21
FreeBSD's native target uses linked-lists to keep track of pending fork events and fake vfork done events. Replace the first list with std::list and the second with std::forward_list. gdb/ChangeLog: * fbsd-nat.c (struct fbsd_fork_info): Remove. (fbsd_pending_children): Use std::list. (fbsd_remember_child): Likewise. (fbsd_is_child_pending): Likewise. (fbsd_pending_vfork_done): Use std::forward_list. (fbsd_add_vfork_done): Likewise. (fbsd_is_vfork_done_pending): Likewise. (fbsd_next_vfork_done): Likewise.
2017-08-09Replace remaining cleanups in fbsd-nat.c.John Baldwin1-31/+27
- Use a custom deleter with std::unique_ptr to free() memory returned by kinfo_getvmmap(). - Use std::string with string_printf() to generate the pathname of the procfs 'map' file. - Use gdb::byte_vector to manage the dynamic buffer for TARGET_OBJECT_AUXV and the dynamically allocated array of LWP IDs. gdb/ChangeLog: * fbsd-nat.c [HAVE_KINFO_GETVMMAP] (struct free_deleter): New. (fbsd_find_memory_regions): Use free_deleter with std::unique_ptr. [!HAVE_KINFO_GETVMMAP] (fbsd_find_memory_regions): Use std::string for `mapfilename'. (fbsd_xfer_partial): Use gdb::byte_vector. (fbsd_add_threads): Likewise.
2017-08-09Fix compile in the !HAVE_KINFO_GETVMMAP case.John Baldwin1-2/+4
gdb/ChangeLog: * fbsd-nat.c: [!HAVE_KINFO_GETVMMAP]: Include <sys/user.h> and "filestuff.h". (fbsd_find_memory_regions): Fix `mapfile' initialization.
2017-08-03Use gdb_file_up in fbsd-nat.cTom Tromey1-4/+2
This updates fbsd-nat.c to use gdb_file_up. This removes a use of a cleanup, and helps remove make_cleanup_fclose in a later patch. I have no way to test this patch. ChangeLog 2017-08-03 Tom Tromey <tom@tromey.com> * fbsd-nat.c (fbsd_find_memory_regions): Update.
2017-07-07Fetch signal information for native FreeBSD processes.John Baldwin1-0/+162
Use the `pl_siginfo' field in the `struct ptrace_lwpinfo' object returned by the PT_LWPINFO ptrace() request to supply the current contents of $_siginfo for each thread. Note that FreeBSD does not supply a way to modify the signal information for a thread, so $_siginfo is read-only for FreeBSD. To handle 32-bit processes on a 64-bit host, define types for 32-bit compatible siginfo_t and convert the 64-bit siginfo_t to the 32-bit equivalent when supplying information for a 32-bit process. gdb/ChangeLog: * fbsd-nat.c [PT_LWPINFO && __LP64__] (union sigval32) (struct siginfo32): New. [PT_LWPINFO] (fbsd_siginfo_size, fbsd_convert_siginfo): New. (fbsd_xfer_partial) [PT_LWPINFO]: Handle TARGET_OBJECT_SIGNAL_INFO via ptrace(PT_LWPINFO).
2017-04-18PR threads/20743: Don't attempt to suspend or resume exited threads.John Baldwin1-34/+26
When resuming a native FreeBSD process, ignore exited threads when suspending/resuming individual threads prior to continuing the process. gdb/ChangeLog: PR threads/20743 * fbsd-nat.c (resume_one_thread_cb): Remove. (resume_all_threads_cb): Remove. (fbsd_resume): Use ALL_NON_EXITED_THREADS instead of iterate_over_threads.
2017-04-05-Wwrite-strings: Constify target_pid_to_str and target_thread_extra_thread_infoPedro Alves1-1/+1
-Wwrite-strings flagged a missing cast for example here: static char * ravenscar_extra_thread_info (struct target_ops *self, struct thread_info *tp) { return "Ravenscar task"; Since callers are not supposed to free the string returned by these methods, change the methods' signature to return const strings. gdb/ChangeLog: 2017-04-05 Pedro Alves <palves@redhat.com> * aix-thread.c (aix_thread_pid_to_str) (aix_thread_extra_thread_info): Constify. * bsd-kvm.c (bsd_kvm_pid_to_str): Constify. * bsd-uthread.c (bsd_uthread_extra_thread_info) (bsd_uthread_pid_to_str): Constify. * corelow.c (core_pid_to_str): Constify. * darwin-nat.c (darwin_pid_to_str): Constify. * fbsd-nat.c (fbsd_pid_to_str): Constify. * fbsd-tdep.c (fbsd_core_pid_to_str, gdbarch_core_pid_to_str): Constify. * gnu-nat.c (gnu_pid_to_str): Constify. * go32-nat.c (go32_pid_to_str): Constify. * i386-cygwin-tdep.c (i386_windows_core_pid_to_str): Constify. * inf-ptrace.c (inf_ptrace_pid_to_str): Constify. * inferior.c (inferior_pid_to_str): Constify. * linux-nat.c (linux_nat_pid_to_str): Constify. * linux-tdep.c (linux_core_pid_to_str): Constify. * linux-thread-db.c (thread_db_pid_to_str) (thread_db_extra_thread_info): Constify. * nto-tdep.c (nto_extra_thread_info): Constify. * nto-tdep.h (nto_extra_thread_info): Constify. * obsd-nat.c (obsd_pid_to_str): Constify. * procfs.c (procfs_pid_to_str): Constify. * ravenscar-thread.c (ravenscar_extra_thread_info) (ravenscar_pid_to_str): Constify. * remote-sim.c (gdbsim_pid_to_str): Constify. * remote.c (remote_threads_extra_info, remote_pid_to_str): Constify. * sol-thread.c (solaris_pid_to_str): Constify. * sol2-tdep.c (sol2_core_pid_to_str): Constify. * sol2-tdep.h (sol2_core_pid_to_str): Constify. * target.c (default_pid_to_str, target_pid_to_str) (normal_pid_to_str, default_pid_to_str): Constify. * target.h (target_ops::to_pid_to_str) (target_ops::to_extra_thread_info): Constify.

2017-04-04Remove support for using the bsd-uthread target on FreeBSD.John Baldwin1-1/+1
The bsd-uthread target supports an old thread library ("libc_r") that was last included in FreeBSD release 6.4 released in 2008. However, this library has not been used as the default library since FreeBSD 5.0 (2003) and 4.11 (2005). Thread support for modern FreeBSD binaries is provided via "normal" LWP support in core files and the native FreeBSD target. gdb/ChangeLog: * amd64-fbsd-tdep.c: Remove "bsd-uthread.h" include. (amd64fbsd_jmp_buf_reg_offset): Remove. (amd64fbsd_supply_uthread): Remove function. (amd64fbsd_collect_uthread): Remove function. (amd64fbsd_init_abi): Don't set bsd-uthread callbacks. * configure.tgt (i[34567]86-*-freebsd*): Remove bsd-uthread.o. (x86_64-*-freebsd*): Remove bsd-uthread.o. (fbsd-nat.c): Update comment. * i386-fbsd-tdep.c: Remove "bsd-uthread.h" include. (i386fbsd_jmp_buf_reg_offset): Remove. (i386fbsd_supply_uthread): Remove function.
