* linux-aarch64-low.c (aarch64_arch_setup): Remove code and call
aarch64_linux_get_debug_reg_capacity.
Move common aarch64 HW breakpoint/watchpoint code to nat/ When I look at test fails related to watchpoint on aarch64-linux, I find there are some code duplicates between GDB and GDBserver. This patch is to move some of them to a nat/aarch64-linux-hw-point.{h,c}. The only change I do is about the dr_changed_t typedef, which was ULONGEST in GDB and 'unsigned long long' in GDBserver. Each bit of dr_changed_t represents a status of each HW breakpoint or watchpoint register, and the max number of HW breakpoint or watchpoint registers is 16, so the width of 'unsigned long long' is sufficient. gdb: 2015-07-17 Yao Qi <yao.qi@linaro.org> * Makefile.in (HFILES_NO_SRCDIR): Add nat/aarch64-linux-hw-point.h.

Pass aarch64_debug_reg_state to functions Some functions on handling HW watchpoint in GDB and GDBserver looks the same except the code getting debug register state from current inferior. In GDB, we get debug register state like this: state = aarch64_get_debug_reg_state (ptid_get_pid (inferior_ptid)); while in GDBserver, we get debug register state like this: state = aarch64_get_debug_reg_state (); This patch is to move two lines above out of some functions, and pass aarch64_debug_reg_state to these functions, in this way, these functions are the same, and can be moved to a common place. gdb: 2015-07-17 Yao Qi <yao.qi@linaro.org> * aarch64-linux-nat.c (aarch64_handle_breakpoint): Add argument state and don't call aarch64_get_debug_reg_state.

Initialize last_resume_kind for remote fork child This patch fixes some intermittent test failures in gdb.base/foll-vfork.exp where a vfork child would be (incorrectly) resumed when handling the vfork event. In this case the result was a subsequent event reported to the client side as a SIGTRAP delivered to the as-yet-unknown child thread. The new thread was resumed (incorrectly) in linux-low.c when resume_stopped_resumed_lwps was called from linux_wait_for_event_filtered after the vfork event had been handled in handle_extended_wait. Gdbserver/linux-low.c's add_thread function creates threads with last_resume_kind == resume_continue by default. This field is used by resume_stopped_resumed_lwps to decide whether to perform the resume: static void resume_stopped_resumed_lwps (struct inferior_list_entry *entry) { struct thread_info *thread = (struct thread_info *) entry; struct lwp_info *lp = get_thread_lwp (thread); if (lp->stopped && !lp->status_pending_p && thread->last_resume_kind != resume_stop && thread->last_status.kind == TARGET_WAITKIND_IGNORE) { So the fix is to make sure to set thread->last_resume_kind to resume_stop. Here we do that for new fork children in gdbserver/linux-low.c:handle_extended_wait. In addition, it seemed prudent to initialize lwp_info.status_pending_p for the new fork child. I also rearranged the initialization code so that all of the lwp_info initialization was together, rather than intermixed with thread_info and process_info initialization. Tested native, native-gdbserver, native-extended-gdbserver on x86_64 GNU/Linux. gdb/gdbserver/ * linux-low.c (handle_extended_wait): Initialize thread_info.last_resume_kind for new fork children.

Arch-specific remote follow fork This patch implements the architecture-specific pieces of follow-fork for remote and extended-remote Linux targets, which in the current implementation copyies the parent's debug register state into the new child's data structures. This is required for x86, arm, aarch64, and mips. This follows the native implementation as closely as possible by implementing a new linux_target_ops function 'new_fork', which is analogous to 'linux_nat_new_fork' in linux-nat.c. In gdbserver, the debug registers are stored in the process list, instead of an architecture-specific list, so the function arguments are process_info pointers instead of an lwp_info and a pid as in the native implementation. In the MIPS implementation the debug register mirror is stored differently from x86, ARM, and aarch64, so instead of doing a simple structure assignment I had to clone the list of watchpoint structures. Tested using gdb.threads/watchpoint-fork.exp on x86, and ran manual tests on a MIPS board and an ARM board. Aarch64 hasn't been tested. gdb/gdbserver/ChangeLog: * linux-aarch64-low.c (aarch64_linux_new_fork): New function.

Extended-remote Linux follow fork This patch implements basic support for follow-fork and detach-on-fork on extended-remote Linux targets. Only 'fork' is supported in this patch; 'vfork' support is added n a subsequent patch. This patch depends on the previous patches in the patch series. Sufficient extended-remote functionality has been implemented here to pass gdb.base/multi-forks.exp, as well as gdb.base/foll-fork.exp with the catchpoint tests commented out. Some other fork tests fail with this patch because it doesn't provide the architecture support needed for watchpoint inheritance or fork catchpoints. The implementation follows the same general structure as for the native implementation as much as possible. This implementation includes: * enabling fork events in linux-low.c in initialize_low and linux_enable_extended_features * handling fork events in gdbserver/linux-low.c:handle_extended_wait - when a fork event occurs in gdbserver, we must do the full creation of the new process, thread, lwp, and breakpoint lists. This is required whether or not the new child is destined to be detached-on-fork, because GDB will make target calls that require all the structures. In particular we need the breakpoint lists in order to remove the breakpoints from a detaching child. If we are not detaching the child we will need all these structures anyway. - as part of this event handling we store the target_waitstatus in a new member of the parent lwp_info structure, 'waitstatus'. This is used to store extended event information for reporting to GDB. - handle_extended_wait is given a return value, denoting whether the handled event should be reported to GDB. Previously it had only handled clone events, which were never reported. * using a new predicate in gdbserver to control handling of the fork event (and eventually all extended events) in linux_wait_1. The predicate, extended_event_reported, checks a target_waitstatus.kind for an extended ptrace event. * implementing a new RSP 'T' Stop Reply Packet stop reason: "fork", in gdbserver/remote-utils.c and remote.c. * implementing new target and RSP support for target_follow_fork with target extended-remote. (The RSP components were actually defined in patch 1, but they see their first use here). - remote target routine remote_follow_fork, which just sends the 'D;pid' detach packet to detach the new fork child cleanly. We can't just call target_detach because the data structures for the forked child have not been allocated on the host side. Tested on x64 Ubuntu Lucid, native, remote, extended-remote. gdb/gdbserver/ChangeLog: * linux-low.c (handle_extended_wait): Implement return value, rename argument 'event_child' to 'event_lwp', handle PTRACE_EVENT_FORK, call internal_error for unrecognized event.

Identify remote fork event support This patch implements a mechanism for GDB to determine whether fork events are supported in gdbserver. This is a preparatory patch for remote fork and exec event support. Two new RSP packets are defined to represent fork and vfork event support. These packets are used just like PACKET_multiprocess_feature to denote whether the corresponding event is supported. GDB sends fork-events+ and vfork-events+ to gdbserver to inquire about fork event support. If the response enables these packets, then GDB knows that gdbserver supports the corresponding events and will enable them. Target functions used to query for support are included along with each new packet. In order for gdbserver to know whether the events are supported at the point where the qSupported packet arrives, the code in nat/linux-ptrace.c had to be reorganized. Previously it would test for fork/exec event support, then enable the events using the pid of the inferior. When the qSupported packet arrives there may not be an inferior. So the mechanism was split into two parts: a function that checks whether the events are supported, called when gdbserver starts up, and another that enables the events when the inferior stops for the first time. Another gdbserver change was to add some global variables similar to multi_process, one per new packet. These are used to control whether the corresponding fork events are enabled. If GDB does not inquire about the event support in the qSupported packet, then gdbserver will not set these "report the event" flags. If the flags are not set, the events are ignored like they were in the past. Thus, gdbserver will never send fork event notification to an older GDB that doesn't recognize fork events. Tested on Ubuntu x64, native/remote/extended-remote, and as part of subsequent patches in the series. gdb/gdbserver/ChangeLog: * linux-low.c (linux_supports_fork_events): New function.

[gdbserver] Disable conditional breakpoints on no-hardware-single-step targets GDBserver steps over breakpoint if the condition is false, but if target doesn't support hardware single step, the step over is very simple, if not incorrect, in linux-arm-low.c: /* We only place breakpoints in empty marker functions, and thread locking is outside of the function. So rather than importing software single-step, we can just run until exit. */ static CORE_ADDR arm_reinsert_addr (void) { struct regcache *regcache = get_thread_regcache (current_thread, 1); unsigned long pc; collect_register_by_name (regcache, "lr", &pc); return pc; } and linux-mips-low.c does the same. GDBserver sets a breakpoint at the return address of the current function, resume and wait the program hits the breakpoint in order to achieve "breakpoint step over". What if program hits other user breakponits during this "step over"? It is worse if the arm/thumb interworking is considered. Nowadays, GDBserver arm backend unconditionally inserts arm breakpoint, /* Define an ARM-mode breakpoint; we only set breakpoints in the C library, which is most likely to be ARM. If the kernel supports clone events, we will never insert a breakpoint, so even a Thumb C library will work; so will mixing EABI/non-EABI gdbserver and application. */ (const unsigned char *) &arm_breakpoint, (const unsigned char *) &arm_eabi_breakpoint, note that the comments are no longer valid as C library can be compiled in thumb mode. When GDBserver steps over a breakpoint in arm mode function, which returns to thumb mode, GDBserver will insert arm mode breakpoint by mistake and the program will crash. GDBserver alone is unable to determine the arm/thumb mode given a PC address. See how GDB does it in arm-tdep.c:arm_pc_is_thumb. After thinking about how to teach GDBserver inserting right breakpoint (arm or thumb) for a while, I reconsider it from a different direction that it may be unreasonable to run target-side conditional breakpoint for targets without hardware single step. Pedro also pointed this out here https://sourceware.org/ml/gdb-patches/2015-04/msg00337.html This patch is to add a new target_ops hook supports_conditional_breakpoints, and only reply ";ConditionalBreakpoints+" if it is true. On linux targets, supports_conditional_breakpoints returns true if target has hardware single step, on other targets, (win32, lynx, nto, spu), set it to NULL, because conditional breakpoint is a linux-specific feature. gdb/gdbserver: 2015-05-08 Yao Qi <yao.qi@linaro.org> * linux-low.c (linux_supports_conditional_breakpoints): New function.

GDBserver handles all kinds of breakpoints/watchpoints through target methods. However, some target backends, such as arm, don't support Z0 packet but need software breakpoint to do breakpoint stepping over in linux-low.c:start_step_over, if (can_hardware_single_step ()) { step = 1; } else { CORE_ADDR raddr = (*the_low_target.breakpoint_reinsert_addr) (); set_reinsert_breakpoint (raddr); step = 0; } a software breakpoint is requested to the backend, and the error is triggered. This problem should affect targets having breakpoint_reinsert_addr hooked. Instead of handling memory breakpoint in these affected linux backend, this patch handles memory breakpoint in linux_{insert,remove}_point, that, if memory breakpoint is requested, call {insert,remove}_memory_breakpoint respectively. Then, it becomes unnecessary to handle memory breakpoint for linux x86 backend, so this patch removes the code there. This patch is tested with GDBserver on x86_64-linux and arm-linux (-marm, -mthumb). Note that there are still some fails in gdb.base/cond-eval-mode.exp with -mthumb, because GDBserver doesn't know how to select the correct breakpoint instruction according to the arm-or-thumb-mode of requested address. This is a separate issue, anyway. gdb/gdbserver: 2015-04-09 Yao Qi <yao.qi@linaro.org> * linux-low.c (linux_insert_point): Call insert_memory_breakpoint if TYPE is raw_bkpt_type_sw.

A few options are missing: . --disable-randomization / --no-disable-randomization is not mentioned. Although the manual has a comment saying these are superceded by QDisableRandomization, that only makes sense for "run" in extended-remote mode. When we start gdbserver passing it a PROG, --disable-randomization / --no-disable-randomization do take effect. So I think we should document these. .

Fix race exposed by gdb.threads/killed.exp On GNU/Linux, this test sometimes FAILs like this: (gdb) run Starting program: /home/pedro/gdb/mygit/build/gdb/testsuite/gdb.threads/killed [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib64/libthread_db.so.1". ptrace: No such process.

The program no longer exists. infrun: stop_waiting FAIL: gdb.threads/killed.exp: run program to completion (timeout) The issue is that here: RSRL: resuming stopped-resumed LWP LWP 18465 at 0x3b36af4b51: step=0 RSRL: resuming stopped-resumed LWP LWP 18461 at 0x3b36af4b51: step=0 The first line shows we had just resumed LWP 18465, which does: void * child_func (void *dummy) { kill (pid, SIGKILL); exit (1); } So if the kernel manages to schedule that thread fast enough, the process may be killed before GDB has a chance to resume LWP 18461. GDBserver has code at the tail end of linux_resume_one_lwp to cope with this: ~~~ ptrace (step ? PTRACE_SINGLESTEP : PTRACE_CONT, lwpid_of (thread), (PTRACE_TYPE_ARG3) 0, /* Coerce to a uintptr_t first to avoid potential gcc warning of coercing an 8 byte integer to a 4 byte pointer. */ (PTRACE_TYPE_ARG4) (uintptr_t) signal); current_thread = saved_thread; if (errno) { /* ESRCH from ptrace either means that the thread was already running (an error) or that it is gone (a race condition). If it's gone, we will get a notification the next time we wait, so we can ignore the error. We could differentiate these two, but it's tricky without waiting; the thread still exists as a zombie, so sending it signal 0 would succeed. So just ignore ESRCH. */ if (errno == ESRCH) return; perror_with_name ("ptrace"); } ~~~ However, that's not a complete fix, because between starting to handle the resume request and getting that PTRACE_CONTINUE, we run other ptrace calls that can also fail with ESRCH, and that end up throwing an error (with perror_with_name). In the case above, I indeed sometimes see resume_stopped_resumed_lwps fail in the registers read: resume_stopped_resumed_lwps (struct lwp_info *lp, void *data) { ... CORE_ADDR pc = regcache_read_pc (regcache); Or e.g., in 32-bit mode, i386_linux_resume has several calls that can throw too. Whether to ignore ptrace errors or not depends on context that is only available somewhere up the call chain. So the fix is to let ptrace errors throw as they do today, and wrap the resume request in a TRY/CATCH that swallows it iff the lwp that we were trying to resume is no longer ptrace-stopped. gdb/gdbserver/ChangeLog: 2015-03-19 Pedro Alves <palves@redhat.com> * linux-low.c (linux_resume_one_lwp): Rename to ...

gdbserver/Linux: unbreak thread event randomization Wanting to make sure the new continue-pending-status.exp test tests both cases of threads 2 and 3 reporting an event, I added counters to the test, to make it FAIL if events for both threads aren't seen. Assuming a well behaved backend, and given a reasonable number of iterations, it should PASS. However, running that against GNU/Linux gdbserver, I found that surprisingly, that FAILed. GDBserver always reported the breakpoint hit for the same thread. Turns out that I broke gdbserver's thread event randomization recently, with git commit 582511be ([gdbserver] linux-low.c: better starvation avoidance, handle non-stop mode too). In that commit I missed that the thread structure also has a status_pending_p field... The end result was that count_events_callback always returns 0, and then if no thread is stepping, select_event_lwp always returns the event thread. IOW, no randomization is happening at all. Quite curious how all the other changes in that patch were sufficient to fix non-stop-fair-events.exp anyway even with that broken. Tested on x86_64 Fedora 20, native and gdbserver. gdb/gdbserver/ChangeLog: 2015-03-19 Pedro Alves <palves@redhat.com> * linux-low.c (count_events_callback, select_event_lwp_callback): Use the lwp's status_pending_p field, not the thread's. gdb/testsuite/ChangeLog: 2015-03-19 Pedro Alves <palves@redhat.com> * gdb.threads/continue-pending-status.exp (saw_thread_2) (saw_thread_3): New globals.

Split TRY_CATCH into TRY + CATCH This patch splits the TRY_CATCH macro into three, so that we go from this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ERROR) { } if (ex.reason < 0) { } ~~~ to this: ~~~ TRY { } CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH ~~~ Thus, we'll be getting rid of the local volatile exception object, and declaring the caught exception in the catch block. This allows reimplementing TRY/CATCH in terms of C++ exceptions when building in C++ mode, while still allowing to build GDB in C mode (using setjmp/longjmp), as a transition step. TBC, after this patch, is it _not_ valid to have code between the TRY and the CATCH blocks, like: TRY { } // some code here. CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH Just like it isn't valid to do that with C++'s native try/catch. By switching to creating the exception object inside the CATCH block scope, we can get rid of all the explicitly allocated volatile exception objects all over the tree, and map the CATCH block more directly to C++'s catch blocks. The majority of the TRY_CATCH -> TRY+CATCH+END_CATCH conversion was done with a script, rerun from scratch at every rebase, no manual editing involved. After the mechanical conversion, a few places needed manual intervention, to fix preexisting cases where we were using the exception object outside of the TRY_CATCH block, and cases where we were using "else" after a 'if (ex.reason) < 0)' [a CATCH after this patch]. The result was folded into this patch so that GDB still builds at each incremental step. END_CATCH is necessary for two reasons: First, because we name the exception object in the CATCH block, which requires creating a scope, which in turn must be closed somewhere. Declaring the exception variable in the initializer field of a for block, like: #define CATCH(EXCEPTION, mask) \ for (struct gdb_exception EXCEPTION; \ exceptions_state_mc_catch (&EXCEPTION, MASK); \ EXCEPTION = exception_none) would avoid needing END_CATCH, but alas, in C mode, we build with C90, which doesn't allow mixed declarations and code. Second, because when TRY/CATCH are wired to real C++ try/catch, as long as we need to handle cleanup chains, even if there's no CATCH block that wants to catch the exception, we need for stop at every frame in the unwind chain and run cleanups, then rethrow. That will be done in END_CATCH. After we require C++, we'll still need TRY/CATCH/END_CATCH until cleanups are completely phased out -- TRY/CATCH in C++ mode will save/restore the current cleanup chain, like in C mode, and END_CATCH catches otherwise uncaugh exceptions, runs cleanups and rethrows, so that C++ cleanups and exceptions can coexist. IMO, this still makes the TRY/CATCH code look a bit more like a newcomer would expect, so IMO worth it even if we weren't considering C++. gdb/ChangeLog. 2015-03-07 Pedro Alves <palves@redhat.com> * common/common-exceptions.c (struct catcher) <exception>: No longer a pointer to volatile exception.

Make functions and variables exported by the IPA be extern "C" Functions and variables that are exported by the IPA DSO (that GDBserver needs to look up) should have "C" mangling, thus be declared with extern "C". Function and variable declarations need the extern "C" marker, but variable definitions can't be marked extern, so the patch splits IP_AGENT_EXPORT into three. Building in C++ mode revealed that a few variables were missing IP_AGENT_EXPORT, thus the IPA has been broken when stripped, even in C mode...

Rename symbols whose names are reserved C++ keywords throughout.
Add --enable-build-with-cxx configure switch This new option, disabled by default for now, allows specifying whether to build GDB, GDBserver, and friends with a C++ (98/03) compiler. The name of the switch should be familiar to those who followed GCC's own C++ conversion process. . Adding -fpermissive to COMPILER in C++ mode (see the new build-with-cxx.m4 file) makes errors like these be warnings instead: gdb/infrun.c:6597:1: error: initializing argument 1 of ‘void sig_print_info(gdb_signal)’ [-fpermissive] sig_print_info (enum gdb_signal oursig) ^ gdb/infrun.c: In function ‘void do_restore_infcall_suspend_state_cleanup(void*)’: gdb/infrun.c:7164:39: error: invalid conversion from ‘void*’ to ‘infcall_suspend_state*’ [-fpermissive] restore_infcall_suspend_state (state); ^ so that the compiler carries on compiling the file. -Werror still catches the warnings, so nothing is lost, only our lifes are made easier by concentrating on getting other more important things out of the way first. There's no way to quiet those warnings. Until they're all fixed, when building in C++ mode, -Werror is disabled by default. . Adding -Wno-narrowing suppresses thousands of instances of this warning: gdb/arm-linux-tdep.c:439:1: error: narrowing conversion of ‘-1’ from ‘int’ to ‘ULONGEST {aka long unsigned int}’ inside { } is ill-formed in C++11 [-Werror=narrowing] gdb/arm-linux-tdep.c:439:1: error: narrowing conversion of ‘-1l’ from ‘LONGEST {aka long int}’ to ‘ULONGEST {aka long unsigned int}’ inside { } is ill-formed in C++11 [-Werror=narrowing] gdb/arm-linux-tdep.c:450:1: error: narrowing conversion of ‘-1’ from ‘int’ to ‘ULONGEST {aka long unsigned int}’ inside { } is ill-formed in C++11 [-Werror=narrowing] We can defer handling those until we target C++11. . Adding -Wno-sign-compare suppresses thousands of instances of this warning: gdb/linux-record.c:1763:32: warning: comparison between signed and unsigned integer expressions [-Wsign-compare] if (tmpulongest == tdep->fcntl_F_GETLK64) ^ . Adding -Wno-write-strings suppresses thousands of instances of this warning: gdb/mi/mi-cmd-var.c: In function ‘void mi_cmd_var_show_attributes(char*, char**, int)’: gdb/mi/mi-cmd-var.c:514:12: warning: deprecated conversion from string constant to ‘char*’ [-Wwrite-strings] attstr = "editable"; ^ gdb/mi/mi-cmd-var.c:516:12: warning: deprecated conversion from string constant to ‘char*’ [-Wwrite-strings] attstr = "noneditable"; ^ For now, it's best to hide these warnings from view until we're '-fpermissive'-clean, and can thus start building with -Werror. The C compiler has always managed to build working GDBs with these issues in the code, so a C++ compiler should too. gdb/ChangeLog: 2015-02-27 Pedro Alves <palves@redhat.com> * Makefile.in (COMPILER): New, get it from autoconf.

GNU/Linux: Stop using libthread_db/td_ta_thr_iter TL;DR - GDB can hang if something refreshes the thread list out of the target while the target is running. GDB hangs inside td_ta_thr_iter. The fix is to not use that libthread_db function anymore. Long version: Running the testsuite against my all-stop-on-top-of-non-stop series is still exposing latent non-stop bugs. I was originally seeing this with the multi-create.exp test, back when we were still using libthread_db thread event breakpoints. The all-stop-on-top-of-non-stop series forces a thread list refresh each time GDB needs to start stepping over a breakpoint (to pause all threads). That test hits the thread event breakpoint often, resulting in a bunch of step-over operations, thus a bunch of thread list refreshes while some threads in the target are running. The commit adds a real non-stop mode test that triggers the issue, based on multi-create.exp, that does an explicit "info threads" when a breakpoint is hit. IOW, it does the same things the as-ns series was doing when testing multi-create.exp. The bug is a race, so it unfortunately takes several runs for the test to trigger it. In fact, even when setting the test running in a loop, it sometimes takes several minutes for it to trigger for me. The race is related to libthread_db's td_ta_thr_iter. This is libthread_db's entry point for walking the thread list of the inferior. Sometimes, when GDB refreshes the thread list from the target, libthread_db's td_ta_thr_iter can somehow see glibc's thread list as a cycle, and get stuck in an infinite loop. The issue is that when a thread exits, its thread control structure in glibc is moved from a "used" list to a "cache" list. These lists are simply circular linked lists where the "next/prev" pointers are embedded in the thread control structure itself. The "next" pointer of the last element of the list points back to the list's sentinel "head". There's only one set of "next/prev" pointers for both lists; thus a thread can only be in one of the lists at a time, not in both simultaneously. So when thread C exits, simplifying, the following happens. A-C are threads. stack_used and stack_cache are the list's heads. Before: stack_used -> A -> B -> C -> (&stack_used) stack_cache -> (&stack_cache) After: stack_used -> A -> B -> (&stack_used) stack_cache -> C -> (&stack_cache) td_ta_thr_iter starts by iterating at the list's head's next, and iterates until it sees a thread whose next pointer points to the list's head again. Thus in the before case above, C's next points to stack_used, indicating end of list. In the same case, the stack_cache list is empty. For each thread being iterated, td_ta_thr_iter reads the whole thread object out of the inferior. This includes the thread's "next" pointer. In the scenario above, it may happen that td_ta_thr_iter is iterating thread B and has already read B's thread structure just before thread C exits and its control structure moves to the cached list. Now, recall that td_ta_thr_iter is running in the context of GDB, and there's no locking between GDB and the inferior. From it's local copy of B, td_ta_thr_iter believes that the next thread after B is thread C, so it happilly continues iterating to C, a thread that has already exited, and is now in the stack cache list. After iterating C, td_ta_thr_iter finds the stack_cache head, which because it is not stack_used, td_ta_thr_iter assumes it's just another thread. After this, unless the reverse race triggers, GDB gets stuck in td_ta_thr_iter forever walking the stack_cache list, as no thread in thatlist has a next pointer that points back to stack_used (the terminating condition). Before fully understanding the issue, I tried adding cycle detection to GDB's td_ta_thr_iter callback. However, td_ta_thr_iter skips calling the callback in some cases, which means that it's possible that the callback isn't called at all, making it impossible for GDB to break the loop. I did manage to get GDB stuck in that state more than once. Fortunately, we can avoid the issue altogether. We don't really need td_ta_thr_iter for live debugging nowadays, given PTRACE_EVENT_CLONE. We already know how to map and lwp id to a thread id without iterating (thread_from_lwp), so use that more. gdb/ChangeLog: 2015-02-20 Pedro Alves <palves@redhat.com> * linux-nat.c (linux_handle_extended_wait): Call thread_db_notice_clone whenever a new clone LWP is detected.

record btrace: add configuration struct Add a struct to describe the branch trace configuration and use it for enabling branch tracing. The user will be able to set configuration fields for each tracing format to be used for new threads. The actual configuration that is active for a given thread will be shown in the "info record" command. At the moment, the configuration struct only contains a format field that is set to the only available format. The format is the only configuration option that can not be set via set commands.

Linux: don't resume new LWPs until we've pulled all events out of the kernel Since the starvation avoidance series (https://sourceware.org/ml/gdb-patches/2014-12/msg00631.html), both GDB and GDBserver pull all events out of ptrace before deciding which event to process. There's one problem with that though. Because we resume new threads immediately when we see a PTRACE_EVENT_CLONE event, if the program constantly spawns threads fast enough, new threads can spawn threads faster we can pull events out of the kernel, and thus we'd get stuck in an infinite loop, never returning any event to the core to process. I occasionally see this happen with the attach-many-short-lived-threads.exp test against gdbserver. The fix is to delay resuming new threads until we've pulled out all events out of the kernel. On native, we already have the resume_stopped_resumed_lwps function that knows to resume LWPs that are stopped with no event to report to the core. So the patch just adds another use. GDBserver didn't have the equivalent yet, so the patch adds one. Tested on x86_64 Fedora 20, native and gdbserver (remote and extended-remote). gdb/gdbserver/ChangeLog: 2015-02-04 Pedro Alves <palves@redhat.com> * linux-low.c (handle_extended_wait): Don't resume LWPs here.

Detect 64-bit-ness in PowerPC Book III-E This patch is to teach both GDB and GDBServer to detect 64-bit inferior correctly. We find a problem that GDBServer is unable to detect on a e5500 core processor. Current GDBServer assumes that MSR is a 64-bit register, but MSR is a 32-bit register in Book III-E. This patch is to fix this problem by checking the right bit in MSR, in order to handle both Book III-S and Book III-E. In order to detect Book III-S and Book III-E, we check the PPC_FEATURE_BOOKE from the host's HWCAP (by getauxval on glibc >= 2.16. If getauxval doesn't exist, we implement the fallback by parsing /proc/self/auxv), because it should an invariant on the same machine cross different processes.

libthread_db: Skip attaching to terminated and joined threads I wrote a test that attaches to a program that constantly spawns short-lived threads, which exposed several issues. This is one of them. On GNU/Linux, attaching to a multi-threaded program sometimes prints out warnings like: ... [New LWP 20700] warning: unable to open /proc file '/proc/-1/status' [New LWP 20850] [New LWP 21019] ... That happens because when a thread exits, and is joined, glibc does: nptl/pthread_join.c: pthread_join () { ... if (__glibc_likely (result == 0)) { /* We mark the thread as terminated and as joined. */ pd->tid = -1; ... /* Free the TCB. */ __free_tcb (pd); } So if we attach or interrupt the program (which does an implicit "info threads") at just the right (or rather, wrong) time, we can find and return threads in the libthread_db/pthreads thread list with kernel thread ID -1. I've filed glibc PR nptl/17707 for this. You'll find more info there. This patch handles this as a special case in GDB. This is actually more than just a cosmetic issue. lin_lwp_attach_lwp will think that this -1 is an LWP we're not attached to yet, and after failing to attach will try to check we were already attached to the process, using a waitpid call, which in this case ends up being "waitpid (-1, ...", which obviously results in GDB potentially discarding an event when it shouldn't...

* thread-db.c (find_new_threads_callback): Ignore thread if the
kernel thread ID is -1.
Linux: on attach, attach to lwps listed under /proc/$pid/task/ ... instead of relying on libthread_db. I wrote a test that attaches to a program that constantly spawns short-lived threads, which exposed several issues. This is one of them. On Linux, we need to attach to all threads of a process (thread group) individually. We currently rely on libthread_db to list the threads, but that is problematic, because libthread_db relies on reading data structures out of the inferior (which may well be corrupted). If threads are being created or exiting just while we try to attach, we may trip on inconsistencies in the inferior's thread list. To work around that, when we see a seemingly corrupt list, we currently retry a few times: static void thread_db_find_new_threads_2 (ptid_t ptid, int until_no_new) { ... if (until_no_new) { /* Require 4 successive iterations which do not find any new threads. The 4 is a heuristic: there is an inherent race here, and I have seen that 2 iterations in a row are not always sufficient to "capture" all threads. */ ... That heuristic may well fail, and when it does, we end up with threads in the program that aren't under GDB's control. That's obviously bad and results in quite mistifying failures, like e.g., the process dying for seeminly no reason when a thread that wasn't attached trips on a breakpoint. There's really no reason to rely on libthread_db for this nowadays when we have /proc mounted. In that case, which is the usual case, we can list the LWPs from /proc/PID/task/. In fact, GDBserver is already doing this. The patch factors out that code that knows to walk the task/ directory out of GDBserver, and makes GDB use it too. Like GDBserver, the patch makes GDB attach to LWPs and _not_ wait for them to stop immediately. Instead, we just tag the LWP as having an expected stop. Because we can only set the ptrace options when the thread stops, we need a new flag in the lwp structure to keep track of whether we've already set the ptrace options, just like in GDBserver. Note that nothing issues any ptrace command to the threads between the PTRACE_ATTACH and the stop, so this is safe (unlike one scenario described in gdbserver's linux-low.c). When we attach to a program that has threads exiting while we attach, it's easy to race with a thread just exiting as we try to attach to it, like: #1 - get current list of threads #2 - attach to each listed thread #3 - ooops, attach failed, thread is already gone As this is pretty normal, we shouldn't be issuing a scary warning in step #3. When #3 happens, PTRACE_ATTACH usually fails with ESRCH, but sometimes we'll see EPERM as well. That happens when the kernel still has the thread in its task list, but the thread is marked as dead. Unfortunately, EPERM is ambiguous and we'll get it also on other scenarios where the thread isn't dead, and in those cases, it's useful to get a warning. To distiguish the cases, when we get an EPERM failure, we open /proc/PID/status, and check the thread's state -- if the /proc file no longer exists, or the state is "Z (Zombie)" or "X (Dead)", we ignore the EPERM error silently; otherwise, we'll warn. Unfortunately, there seems to be a kernel race here. Sometimes I get EPERM, and then the /proc state still indicates "R (Running)"... If we wait a bit and retry, we do end up seeing X or Z state, or get an ESRCH. I thought of making GDB retry the attach a few times, but even with a 500ms wait and 4 retries, I still see the warning sometimes. I haven't been able to identify the kernel path that causes this yet, but in any case, it looks like a kernel bug to me. As this just results failure to suppress a warning that we've been printing since about forever anyway, I'm just making the test cope with it, and issue an XFAIL. gdb/gdbserver/ 2015-01-09 Pedro Alves <palves@redhat.com> * linux-low.c (linux_attach_fail_reason_string): Move to nat/linux-ptrace.c, and rename.

[Linux] Ask kernel to kill inferior when GDB terminates This patch enhances GDB on GNU/Linux systems in the situation where we are debugging an inferior that was created from GDB (as opposed to attached to), by asking the kernel to kill the inferior if GDB terminates without doing it itself. This would typically happen when GDB encounters a problem and crashes, or when it gets killed by an external process. This can be observed by starting a program under GDB, and then killing GDB with signal 9. After GDB is killed, the inferior still remains. This patch also fixes GDBserver similarly. This fix is conditional on the kernel supporting the PTRACE_O_EXITKILL feature. On older kernels, the behavior remains unchanged. gdb/ChangeLog: * nat/linux-ptrace.h (PTRACE_O_EXITKILL): Define if not already defined.

Use PTRACE_SINGLESTEP_ONE when single-stepping one thread. Currently, when we receive a request to single-step one single thread (Eg, when single-stepping out of a breakpoint), we use the PTRACE_SINGLESTEP pthread request, which does single-step the corresponding thread, but also resumes execution of all other threads in the inferior. This causes problems when debugging programs where another thread receives multiple debug events while trying to single-step a specific thread out of a breakpoint (with infrun traces turned on): (gdb) continue Continuing. infrun: clear_proceed_status_thread (Thread 126) [...] infrun: clear_proceed_status_thread (Thread 142) [...] infrun: clear_proceed_status_thread (Thread 146) infrun: clear_proceed_status_thread (Thread 125) infrun: proceed (addr=0xffffffff, signal=GDB_SIGNAL_DEFAULT, step=0) infrun: resume (step=1, signal=GDB_SIGNAL_0), trap_expected=1, current thread [Thread 142] at 0x10684838 infrun: wait_for_inferior () infrun: target_wait (-1, status) = infrun: 42000 [Thread 146], infrun: status->kind = stopped, signal = GDB_SIGNAL_REALTIME_34 infrun: infwait_normal_state infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x10a187f4 infrun: context switch infrun: Switching context from Thread 142 to Thread 146 infrun: random signal (GDB_SIGNAL_REALTIME_34) infrun: switching back to stepped thread infrun: Switching context from Thread 146 to Thread 142 infrun: resume (step=1, signal=GDB_SIGNAL_0), trap_expected=1, current thread [Thread 142] at 0x10684838 infrun: prepare_to_wait [...handling of similar events for threads 145, 144 and 143 snipped...] infrun: prepare_to_wait infrun: target_wait (-1, status) = infrun: 42000 [Thread 146], infrun: status->kind = stopped, signal = GDB_SIGNAL_REALTIME_34 infrun: infwait_normal_state infrun: TARGET_WAITKIND_STOPPED infrun: stop_pc = 0x10a187f4 infrun: context switch infrun: Switching context from Thread 142 to Thread 146 ../../src/gdb/inline-frame.c:339: internal-error: skip_inline_frames: Assertion `find_inline_frame_state (ptid) == NULL' failed. What happens is that GDB keeps sending requests to resume one specific thread, and keeps receiving debugging events for other threads. Things break down when the one of the other threads receives a debug event for the second time (thread 146 in the example above). This patch fixes the problem by making sure that only one thread gets resumed, thus preventing the other threads from generating an unexpected event. gdb/gdbserver/ChangeLog: * lynx-low.c (lynx_resume): Use PTRACE_SINGLESTEP_ONE if N == 1.

[gdbserver/lynx] spurious failure to write in inferior memory We noticed the following error on ppc-lynx178, using just about any program: (gdb) tar remote mytarget:4444 Remote debugging using mytarget:4444 0x000100c8 in _start () (gdb) b try Breakpoint 1 at 0x10844: file try.adb, line 11. (gdb) cont Continuing. !!!-> Cannot remove breakpoints because program is no longer writable. !!!-> Further execution is probably impossible. Breakpoint 1, try () at try.adb:11 11 Local : Integer := 18; And, of course, trying to continue yielded the expected outcome: (gdb) c Continuing. warning: Error removing breakpoint 1 Cannot remove breakpoints because program is no longer writable. Further execution is probably impossible. It turns out that the problem is caused by an intentional test against a variable with an undefined value. After GDB receives notification of the inferior stopping, it tries to remove the breakpoint by sending a memory-write packet ("X10844,4:9 "). This leads us to lynx_write_memory, where it tries to split the memory-write into chunks of 4 bytes. And, in order to handle writes which are not aligned on word boundaries, we have the following code: if (skip > 0 || truncate > 0) /* We need to read the memory at this address in order to preserve the data that we are not overwriting. */ lynx_read_memory (addr, (unsigned char *) &buf, xfer_size); if (errno) return errno; (the comment explains what the code is about). Unfortunately, the not-so-glaring error that we've made here is that we're checking ERRNO regardless of whether we've called lynx_read_memory. In our case, because we are writing 4 bytes aligned on a word boundary, we do not call lynx_read_memory and therefore test an ERRNO with an undefined value. gdb/gdbserver/ChangeLog: * lynx-low.c (lynx_write_memory): Put lynx_read_memory and corresponding ERRNO check in same block.

GDBserver: don't resume all threads if the Hc thread disapears There's code in linux_wait_1 that resumes all threads if the Hc thread disappears. It's the wrong thing to do, as GDB has told GDBserver to resume only one thread, because e.g., the user has scheduler-locking enabled, or because GDB was stepping the program over a breakpoint. Resuming all threads behind GDB's back can't be good in either case. The right thing to do is to detect that that the (only) resumed thread is gone, and let GDB know about it. The Linux backend is already doing that nowadays, since: commit fa96cb382c12b099675c5cc238aaa7352a3fd3d7 Author: Pedro Alves <palves@redhat.com> AuthorDate: Thu Feb 27 14:30:08 2014 +0000 Teach GDBserver's Linux backend about no unwaited-for children (TARGET_WAITKIND_NO_RESUMED). The backend detects that all resumed threads have disappeared, and returns TARGET_WAITKIND_NO_RESUMED to the core of GDBserver, which then reports an error to GDB. There's no need to frob the passed in ptid to wait for the continue thread either -- linux_wait_for_event only returns events for resumed threads. The badness (of resuming threads) can actually be observed in the testsuite, if we force-disable vCont support in GDBserver -- before the patch, gdb.threads/no-unwaited-for-left.exp hangs if we disable vCont: (gdb) continue Continuing. FAIL: gdb.threads/no-unwaited-for-left.exp: continue to breakpoint: break-here (timeout) ... more cascading timeouts ....

Otherwise the core x86 debug registers code can get confused if the inferior itself changes the debug registers since GDB last set them. This is also a requirement for being able to set watchpoints while the target is running, if/when we get to it on Windows. See the big comment in x86_dr_stopped_data_address. Seems to me this may also fixes propagating watchpoints to all threads -- continue_one_thread only calls win32_set_thread_context (what copies the DR registers to the thread), if something already fetched the thread's context before. Something else may be masking this issue, I haven't checked. Smoke tested by running gdbserver under Wine, connecting to it from GNU/Linux, and checking that I could trigger a watchpoint as expected. Joel tested it on x86-windows using AdaCore's testsuite. gdb/gdbserver/ 2014-10-15 Pedro Alves <palves@redhat.com> PR server/17487 * win32-arm-low.c (arm_set_thread_context): Remove current_event parameter.

Honour SIGILL and SIGSEGV in cancel breakpoint and event lwp selection I see the following fail on arm-none-linux-gnueabi testing, (gdb) continue^M Continuing.^M ^M Program received signal SIGILL, Illegal instruction.^M [Switching to Thread 1003]^M handler (signo=10) at /scratch/yqi/arm-none-linux-gnueabi/src/gdb-trunk/gdb/testsuite/gdb.threads/sigstep-threads.c:33^M 33 tgkill (getpid (), gettid (), SIGUSR1); /* step-2 */^M (gdb) FAIL: gdb.threads/sigstep-threads.exp: continue the cause is that GDBserver doesn't cancel the breakpoint if the stop signal is SIGILL. The kernel used here is a little old, 2.6.x, and doesn't translate SIGILL to SIGTRAP when program hits breakpoint instruction (which is an illegal instruction actually). GDB and GDBserver can translate SIGILL to SIGTRAP under certain circumstance, so it is not a problem here. See gdbserver/linux-low.c:linux_wait_1 /* If this event was not handled before, and is not a SIGTRAP, we report it. SIGILL and SIGSEGV are also treated as traps in case a breakpoint is inserted at the current PC. If this target does not support internal breakpoints at all, we also report the SIGTRAP without further processing; it's of no concern to us. */ maybe_internal_trap = (supports_breakpoints () && (WSTOPSIG (w) == SIGTRAP || ((WSTOPSIG (w) == SIGILL || WSTOPSIG (w) == SIGSEGV) && (*the_low_target.breakpoint_at) (event_child->stop_pc)))); However, SIGILL and SIGSEGV is not considered when cancelling breakpoint, which causes the fail above. That is, when GDB is doing software single step on address ADDR, both thread A and thread B hits the software single step breakpoint, and get SIGILL. GDB selects the event from thread A, removes the software single step breakpoint, and resume the program. The event (SIGILL) from thread B is reported to GDB, but GDB doesn't regard this SIGILL as SIGTRAP, because the breakpoint on address ADDR was removed, so GDB reports "Program received signal SIGILL". The patch is to allow calling cancel_breakpoint if the signal is SIGILL and SIGSEGV. This patch fixes the fail above. Likewise, event lwp selection should honour SIGILL and SIGSEGV too. gdb/gdbserver: 2014-09-23 Yao Qi <yao@codesourcery.com> * linux-low.c (lp_status_maybe_breakpoint): New function.

Rename current_inferior as current_thread in gdbserver GDB has a function named "current_inferior" and gdbserver has a global variable named "current_inferior", but the two are not equivalent; indeed, gdbserver does not have any real equivalent of what GDB calls an inferior. What gdbserver's "current_inferior" is actually pointing to is a structure describing the current thread. This commit renames current_inferior as current_thread in gdbserver to clarify this. It also renames the function "set_desired_inferior" to "set_desired_thread" and renames various local variables from foo_inferior to foo_thread. gdb/gdbserver/ChangeLog: * inferiors.h (current_inferior): Renamed as...

Rename 32- and 64-bit Intel files from "i386" to "x86" This commit renames nine files that contain code used by both 32- and 64-bit Intel ports such that their names are prefixed with "x86" rather than "i386". All types, functions and variables within these files are likewise renamed such that their names are prefixed with "x86" rather than "i386". This makes GDB follow the convention used by gdbserver such that 32-bit Intel code lives in files called "i386-*", 64-bit Intel code lives in files called "amd64-*", and code for both 32- and 64-bit Intel lives in files called "x86-*". This commit only renames OS-independent files. The Linux ports of both GDB and gdbserver now follow the i386/amd64/x86 convention fully. Some ports still use the old convention where "i386" in file/function/ type/variable names can mean "32-bit only" or "32- and 64-bit" but I don't want to touch ports I can't fully test except where absolutely necessary. gdb/ChangeLog: * i386-nat.h: Renamed as... * x86-nat.h: New file.

When killing lwps, we don't really care about any of the pending status handling of linux_wait_for_event. We can just waitpid the lwps directly, which is also what GDB does (see linux-nat.c:kill_wait_callback). This way the lwps are not deleted while we're walking the list. They'll be deleted by linux_mourn afterwards. This crash triggers several times when running the testsuite against GDBserver with the native-gdbserver board (target remote), but as GDB can't distinguish between GDBserver crashing and "kill" being sucessful, as in both cases the connection is closed (the 'k' packet doesn't require a reply), and the inferior is gone, that results in no FAIL. The patch adds a generic test that catches the issue with extended-remote mode (and works fine with native testing too). Here's how it fails with the native-extended-gdbserver board without the fix: (gdb) info threads Id Target Id Frame 6 Thread 15367.15374 0x000000373bcbc98d in nanosleep () at ../sysdeps/unix/syscall-template.S:81 5 Thread 15367.15373 0x000000373bcbc98d in nanosleep () at ../sysdeps/unix/syscall-template.S:81 4 Thread 15367.15372 0x000000373bcbc98d in nanosleep () at ../sysdeps/unix/syscall-template.S:81 3 Thread 15367.15371 0x000000373bcbc98d in nanosleep () at ../sysdeps/unix/syscall-template.S:81 2 Thread 15367.15370 0x000000373bcbc98d in nanosleep () at ../sysdeps/unix/syscall-template.S:81 * 1 Thread 15367.15367 main () at .../gdb.threads/kill.c:52 (gdb) kill Kill the program being debugged?

x86 Linux watchpoints: Couldn't write debug register: Invalid argument. This patch fixes this on x86 Linux: (gdb) watch *buf@2 Hardware watchpoint 8: *buf@2 (gdb) si 0x00000000004005a7 34 for (i = 0; i < 100000; i++); /* stepi line */ (gdb) del Delete all breakpoints? (y or n) y (gdb) watch *(buf+1)@1 Hardware watchpoint 9: *(buf+1)@1 (gdb) si 0x00000000004005a7 in main () at ../../../src/gdb/testsuite/gdb.base/watchpoint-reuse-slot.c:34 34 for (i = 0; i < 100000; i++); /* stepi line */ Couldn't write debug register: Invalid argument. (gdb) In the example above the debug registers are being switched from this state: CONTROL (DR7): 0000000000050101 STATUS (DR6): 0000000000000000 DR0: addr=0x0000000000601040, ref.count=1 DR1: addr=0x0000000000000000, ref.count=0 DR2: addr=0x0000000000000000, ref.count=0 DR3: addr=0x0000000000000000, ref.count=0 to this: CONTROL (DR7): 0000000000010101 STATUS (DR6): 0000000000000000 DR0: addr=0x0000000000601041, ref.count=1 DR1: addr=0x0000000000000000, ref.count=0 DR2: addr=0x0000000000000000, ref.count=0 DR3: addr=0x0000000000000000, ref.count=0 That is, before, DR7 was setup for watching a 2 byte region starting at what's in DR0 (0x601040). And after, DR7 is setup for watching a 1 byte region starting at what's in DR0 (0x601041). We always write DR0..DR3 before DR7, because if we enable a slot's bits in DR7, you need to have already written the corresponding DR0..DR3 registers -- the kernel rejects the DR7 write with EINVAL otherwise. The error shown above is the opposite scenario. When we try to write 0x601041 to DR0, DR7's bits still indicate intent of watching a 2-byte region. That DR0/DR7 combination is invalid, because 0x601041 is unaligned. To watch two bytes, we'd have to use two slots. So the kernel errors out with EINVAL. Fix this by always first clearing DR7, then writing DR0..DR3, and then setting DR7's bits. A little optimization -- if we're disabling the last watchpoint, then we can clear DR7 just once. The changes to nat/i386-dregs.c make that easier to detect, and as bonus, they make it a little easier to make sense of DR7 in the debug logs, as we no longer need to remember we're seeing stale bits. Tested on x86_64 Fedora 20, native and GDBserver. This adds an exhaustive test that switches between many different combinations of watchpoint types and addresses and widths. gdb/ 2014-06-23 Pedro Alves <palves@redhat.com> * amd64-linux-nat.c (amd64_linux_prepare_to_resume): Clear DR_CONTROL before setting DR0..DR3. * i386-linux-nat.c (i386_linux_prepare_to_resume): Likewise. * nat/i386-dregs.c (i386_remove_aligned_watchpoint): Clear all bits of DR_CONTROL related to the debug register slot being disabled.

Make it easy to make --disable-werror the default for both binutils and gdb The goal of this patch is to provide an easy way to make --disable-werror the default when building binutils, or the parts of binutils that need to get built when building GDB. In development mode, we want to continue making -Werror the default with GCC. But, when making releases, I think we want to make it as easy as possible for regular users to successfully build from sources. GDB already has this kind of feature to turn -Werror as well as the use of the libmcheck library. As GDB Release Manager, I take advantage of it to turn those off after having cut the branch. I'd like to be able to do the same for the binutils bits. And perhaps Tristan will want to do the same for his releases too (not sure, binutils builders might be a little savvier than GDB builders). This patch introduces a new file, called development.sh, which just sets a variable called $development. In our development branches (Eg. "master"), it's set to true. But setting it to false would allow us to change the default behavior of various development-related features to be turned off; in this case, it turns off the use of -Werror by default (use --enable-werror to turn it back on). bfd/ChangeLog: * development.sh: New file. * warning.m4 (AM_BINUTILS_WARNINGS): Source bfd/development.sh.

[GDBserver] Make Zx/zx packet handling idempotent. This patch fixes hardware breakpoint regressions exposed by my fix for "PR breakpoints/7143 - Watchpoint does not trigger when first set", at https://sourceware.org/ml/gdb-patches/2014-03/msg00167.html The testsuite caught them on Linux/x86_64, at least. gdb.sum: gdb.sum: FAIL: gdb.base/hbreak2.exp: next over recursive call FAIL: gdb.base/hbreak2.exp: backtrace from factorial(5.1) FAIL: gdb.base/hbreak2.exp: continue until exit at recursive next test gdb.log: (gdb) next Program received signal SIGTRAP, Trace/breakpoint trap. factorial (value=4) at ../../../src/gdb/testsuite/gdb.base/break.c:113 113 if (value > 1) { /* set breakpoint 7 here */ (gdb) FAIL: gdb.base/hbreak2.exp: next over recursive call Actually, that patch just exposed a latent issue to "breakpoints always-inserted off" mode, not really caused it. After that patch, GDB no longer removes breakpoints at each internal event, thus making some scenarios behave like breakpoint always-inserted on. The bug is easy to trigger with always-inserted on. The issue is that since the target-side breakpoint conditions support, if the stub/server supports evaluating breakpoint conditions on the target side, then GDB is sending duplicate Zx packets to the target without removing them before, and GDBserver is not really expecting that for Z packets other than Z0/z0. E.g., with "set breakpoint always-inserted on" and "set debug remote 1": (gdb) b main Sending packet: $m410943,1#ff...Packet received: 48 Breakpoint 4 at 0x410943: file ../../../src/gdb/gdbserver/server.c, line 3028.

Notice how ref.count increased for each insert_watchpoint call, and then in the end, after GDB told GDBserver to forget about the hardware breakpoint, GDBserver ends with the the first debug register still with ref.count=4! IOW, the hardware breakpoint is left armed on the target, while on the GDB end it's gone. If the program happens to execute 0x410943 afterwards, then the CPU traps, GDBserver reports the trap to GDB, and GDB not having a breakpoint set at that address anymore, reports to the user a spurious SIGTRAP. This is exactly what is happening in the hbreak2.exp test, though in that case, it's a shared library event that triggers a breakpoint_re_set, when breakpoints are still inserted (because nowadays GDB doesn't remove breakpoints while handling internal events), and that recreates breakpoint locations, which likewise forces breakpoint reinsertion and Zx packet resends... That is a lot of bogus Zx duplication that should possibly be addressed on the GDB side. GDB resends Zx packets because the way to change the target-side condition, is to resend the breakpoint to the server with the new condition. (That's an option in the packet: e.g., "Z1,410943,1;X3,220027" for "hbreak main if 0". The packets in the examples above are shorter because the breakpoints don't have conditions attached). GDB doesn't remove the breakpoint first before reinserting it because that'd be bad for non-stop, as it'd open a window where the inferior could miss the breakpoint. The conditions actually haven't changed between the resends, but GDB isn't smart enough to realize that. (TBC, if the target doesn't support target-side conditions, then GDB doesn't trigger these resends (init_bp_location calls mark_breakpoint_location_modified, and that does nothing if condition evaluation is on the host side. The resends are caused by the 'loc->condition_changed = condition_modified.' line.) But, even if GDB was made smarter, GDBserver should really still handle the resends anyway. So target-side conditions also aren't really to blame. The documentation of the Z/z packets says: "To avoid potential problems with duplicate packets, the operations should be implemented in an idempotent way." As such, we may want to fix GDB, but we should definitely fix GDBserver. The fix is a prerequisite for target-side conditions on hardware breakpoints anyway (and while at it, on watchpoints too). GDBserver indeed already treats duplicate Z0 packets in an idempotent way. mem-break.c has the concept of high-level and low-level breakpoints, somewhat similar to GDB's split of breakpoints vs breakpoint locations, and keeps track of multiple breakpoints referencing the same address/location, for the case of an internal GDBserver breakpoint or a tracepoint being set at the same address as a GDB breakpoint. But, it only allows GDB to ever contribute one reference to a software breakpoint location. IOW, if gdbserver sees a Z0 packet for the same address where it already had a GDB breakpoint set, then GDBserver won't create another high-level GDB breakpoint. However, mem-break.c only tracks GDB Z0 breakpoints. The same logic should apply to all kinds of Zx packets. Currently, gdbserver passes down each duplicate Zx (other than Z0) request directly to the target->insert_point routine. The x86 watchpoint support itself refcounts watchpoint / hw breakpoint requests, to handle overlapping watchpoints, and save debug registers. But that code doesn't (and really shouldn't) handle the duplicate requests, assuming that for each insert there will be a corresponding remove. So the fix is to generalize mem-break.c to track all kinds of Zx breakpoints, and filter out duplicates. As mentioned, this ends up adding support for target-side conditions on hardware breakpoints and watchpoints too (though GDB itself doesn't support the latter yet). Probably the least obvious change in the patch is that it kind of turns the breakpoint insert/remove APIs inside out. Before, the target methods were only called for GDB breakpoints. The internal breakpoint set/delete methods inserted memory breakpoints directly bypassing the insert/remove target methods. That's not good when the target should use a debug API to set software breakpoints, instead of relying on GDBserver patching memory with breakpoint instructions, as is the case of NTO. Now removal/insertion of all kinds of breakpoints/watchpoints, either internal, or from GDB, always go through the target methods. The insert_point/remove_point methods no longer get passed a Z packet type, but an internal/raw breakpoint type. They're also passed a pointer to the raw breakpoint itself (note that's still opaque outside mem-break.c), so that insert_memory_breakpoint / remove_memory_breakpoint have access to the breakpoint's shadow buffer. I first tried passing down a new structure based on GDB's "struct bp_target_info" (actually with that name exactly), but then decided against it as unnecessary complication. As software/memory breakpoints work by poking at memory, when setting a GDB Z0 breakpoint (but not internal breakpoints, as those can assume the conditions are already right), we need to tell the target to prepare to access memory (which on Linux means stop threads). If that operation fails, we need to return error to GDB. Seeing an error, if this is the first breakpoint of that type that GDB tries to insert, GDB would then assume the breakpoint type is supported, but it may actually not be. So we need to check whether the type is supported at all before preparing to access memory. And to solve that, the patch adds a new target->supports_z_point_type method that is called before actually trying to insert the breakpoint. Other than that, hopefully the change is more or less obvious. New test added that exercises the hbreak2.exp regression in a more direct way, without relying on a breakpoint re-set happening before main is reached.

Add AVX512 registers support to GDB and GDBserver. This patch adds support for the Intel(R) Advanced Vector Extensions 512 (Intel(R) AVX-512) registers. Native and remote debugging are covered by this patch. Intel(R) AVX-512 is an extension to AVX to support 512-bit wide SIMD registers in 64-bit mode (XMM0-XMM31, YMM0-YMM31, ZMM0-ZMM31). The number of available registers in 32-bit mode is still 8 (XMM0-7, YMM0-7, ZMM0-7). The lower 256-bits of the ZMM registers are aliased to the respective 256-bit YMM registers. The lower 128-bits are aliased to the respective 128-bit XMM registers. There are also 8 new, dedicated mask registers (K0-K7) in both 32-bit mode and 64-bit mode. For more information please see Intel(R) Developer Zone: Intel(R) AVX http://software.intel.com/en-us/intel-isa-extensions#pid-16007-1495 Intel(R) Architecture Instruction Set Extensions Programming Reference: http://software.intel.com/en-us/file/319433-017pdf 2014-04-24 Michael Sturm <michael.sturm@mintel.com> Walfred Tedeschi <walfred.tedeschi@intel.com> * amd64-linux-nat.c (amd64_linux_gregset32_reg_offset): Add AVX512 registers.

Conditional Z1 breakpoint hangs GDBserver. While trying to fix hbreak2.exp against GDBserver I noticed this... (gdb) hbreak main if 1 Sending packet: $m400580,40#2e...Packet received: e8d2ffffff5dc3554889e54883ec10c745fc00000000eb0eb800000000e8c1ffffff8345fc01817dfce70300007ee9b800000000c9c3662e0f1f840000000000 Sending packet: $m40058f,1#31...Packet received: c7 Hardware assisted breakpoint 1 at 0x40058f: file ../../../src/gdb/testsuite/gdb.base/break-idempotent.c, line 46. Sending packet: $Z1,40058f,1;X3,220127#9b... *hangs forever* The issue is that nothing advances the packet pointer if add_breakpoint_condition either fails to parse the agent expression, or fails to find the breakpoint, resulting in an infinite loop in process_point_options. The latter case should really be fixed by GDBserver tracking GDB Z1 breakpoints in its breakpoint structures like Z0 breakpoints are, but the latter case still needs handling. add_breakpoint_commands has the same issue, though at present I don't know any way to trigger it other than sending a manually cooked packet. Unbelievably, it doesn't look like we have any test that tries setting a conditional hardware breakpoint. Looking at cond-eval-mode.exp, it looks like the file was meant to actually test something, but it's mostly empty today. This patch adds tests that tries all sorts of conditional breakpoints and watchpoints. The test hangs/fails without the GDBserver fix.

Teach GDBserver's Linux backend about no unwaited-for children (TARGET_WAITKIND_NO_RESUMED). GDBserver currently hangs forever in waitpid if the leader thread exits before other threads, or if all resumed threads exit - e.g., next over a thread exit with sched-locking on. This is exposed by leader-exit.exp. leader-exit.exp is part of a series of tests for a set of related problems. See <http://www.sourceware.org/ml/gdb-patches/2011-10/msg00704.html>: " To recap, on the Linux kernel, ptrace/waitpid don't allow reaping the leader thread until all other threads in the group are reaped. When the leader exits, it goes zombie, but waitpid will not return an exit status until the other threads are gone. This is presently exercised by the gdb.threads/leader-exit.exp test. The fix for that test, in linux-nat.c:wait_lwp, handles the case where we see the leader gone when we're stopping all threads to report an event to some other thread to the core. (...) The latter bit about not blocking if there no resumed threads in the process also applies to some other thread exiting, not just the main thread. E.g., this test starts a thread, and runs to a breakpoint in that thread: ... (gdb) c Continuing.

I'm leaving modeling TARGET_WAITKIND_NO_RESUMED in the RSP for a separate pass. (BTW, in case of error in response to a vCont, it would be better for GDB to query the target for the current thread, or re-select one, instead of assuming current inferior_ptid is still the selected thread.) This implementation is a little different from GDB's, because I'm avoiding bringing in more of this broken use of waitpid(PID) into GDBserver. Specifically, this avoids waitpid(PID) when stopping all threads. There's really no need for wait_for_sigstop to wait for each LWP in turn.

move some rsp bits into rsp-low.h This moves various low-level remote serial protocol bits into common/rsp-low.[ch]. This is as close to a pure move as possible. There are some redundancies remaining but those will be dealt with in a subsequent patch. Note that the two variants of remote_escape_output disagreed on the treatment of "*". On the theory that quoting cannot hurt but the absence possibly can, I chose the gdbserver variant to be the canonical one. 2014-02-12 Tom Tromey <tromey@redhat.com> * tracepoint.c: Include rsp-low.h. * remote.h (hex2bin, bin2hex, unpack_varlen_hex): Don't declare. * remote.c: Include rsp-low.h.

(main) <disconnection>: Do it here instead.
[remote/gdbserver] Don't lose signals when reconnecting. Currently, when GDB connects in all-stop mode, GDBserver always responds to the status packet with a GDB_SIGNAL_TRAP, even if the program is actually stopped for some other signal. (gdb) tar rem ... ... (gdb) c Program received signal SIGUSR1, User defined signal 1. (gdb) disconnect (gdb) tar rem ... (gdb) c (Or a GDB crash instead of an explicit disconnect.) This results in the program losing that signal on that last continue, because gdb will tell the target to resume with no signal (to suppress the GDB_SIGNAL_TRAP, due to 'handle SISGTRAP nopass'), and that will actually suppress the real signal the program had stopped for (SIGUSR1). To fix that, I think we should make GDBserver report the real signal the thread had stopped for in response to the status packet: @item ? @cindex @samp{?} packet Indicate the reason the target halted. The reply is the same as for step and continue. But, that raises the question -- which thread are we reporting the status for? Due to how the RSP in all-stop works, we can only report one status. The status packet's response is a stop reply packet, so it includes the thread identifier, so it's not a problem packet-wise. However, GDBserver is currently always reporting the status for first thread in the thread list, even though that may well not be the thread that got the signal that caused the program to stop. So the next logical step would be to report the status for the last_ptid/last_status thread (the last event reported to gdb), if it's still around; and if not, fallback to some other thread. There's an issue on the GDB side with that, though... GDB currently always adds the thread reported in response to the status query as the first thread in its list. That means that if we start with e.g., (gdb) info threads 3 Thread 1003 ... * 2 Thread 1002 ... 1 Thread 1001 ... And reconnect: (gdb) disconnect (gdb) tar rem ... We end up with: (gdb) info threads 3 Thread 1003 ... 2 Thread 1001 ... * 1 Thread 1002 ... Not a real big issue, but it's reasonably fixable, by having GDB fetch/sync the thread list before fetching the status/'?', and then using the status to select the right thread as current on the GDB side. Holes in the thread numbers are squashed before/after reconnection (e.g., 2,3,5 becomes 1,2,3), but the order is preserved, which I think is both good, and good enough. However (yes, there's more...), the previous GDB that was connected might have had gdbserver running in non-stop mode, or could have left gdbserver doing disconnected tracing (which also forces non-stop), and if the new gdb/connection is in all-stop mode, we can end up with more than one thread with a signal to report back to gdb. As we can only report one thread/status (in the all-stop RSP variant; the non-stop variant doesn't have this issue), we get to do what we do at every other place we have this situation -- leave events we can't report right now as pending, so that the next resume picks them up. Note all this ammounts to a QoI change, within the existing framework. There's really no RSP change here. The only user visible change (other than that the signal is program is stopped at isn't lost / is passed to the program), is in "info program", that now can show the signal the program stopped for. Of course, the next resume will respect the pass/nopass setting for the signal in question. It'd be reasonable to have the initial connection tell the user the program was stopped with a signal, similar to when we load a core to debug, but I'm leaving that out for a future change. I think we'll need to either change how handle_inferior_event & co handle stop_soon, or maybe bypass them completely (like fork-child.c:startup_inferior) for that.

On mainline/development, also link GDBserver with -lmcheck. This factors --enable-libmcheck related bits from GDB's configure.ac and makes GDBserver use them too. Specifically, the 'development' global is moved to a separate script to it can be sourced by both GDB and GDBserver, and the --enable-libmcheck/--disable-libmcheck bits proper are moved to a new m4 file. I started out by defining 'development' in the m4 file, but in the end decided against it, as a separate script has the advantage that changing it in release branches does not require regenerating configure, unlike today. I had also started out by making the new GDB_AC_LIBMCHECK itself handle the yes/no default fallback depending on release/developement, but since I had split out 'development' to a separate script, and, GDB needs the python checks anyway (hence we'd need to do the python checks in gdb's configure.ac, and pass in a 'default lmcheck yes/no' parameter to GDB_AC_LIBMCHECK anyway), I ended up keeping GDB_AC_LIBMCHECK isolated from the 'development' global. IOW, it's the caller's business to handle it. Tested on x86_64 Fedora 17. Built GDB and GDBserver with and without --enable-libmcheck, and observed --enable-libmcheck overrides the disablement of -lmcheck caused by python supporting threads, and that GDBserver links with -lmcheck when expected. Also observed that changing the 'development' global, and issuing "make" triggers a relink, and '-lmcheck' is included or not from the link accordingly. gdb/ 2013-07-03 Pedro Alves <palves@redhat.com> * Makefile.in (config.status): Depend on development.sh.

Normalize on PATH_MAX instead of MAXPATHLEN throughout.

Don't remove sys/param.h from GDB's configure.ac, as later tests in the file use HAVE_SYS_PARAM_H checks. Tested on x86_64 Fedora 17.

don't keep a gdb-specific date Right now there are two nightly commits to update a file in the tree with the current date. One commit is for BFD, one is for gdb. It seems unnecessary to me to do this twice. We can make do with a single such commit. This patch changes gdb in a minimal way to reuse the BFD date -- it extracts it from bfd/version.h and changes version.in to use the placeholder string "DATE" for those times when a date is wanted. I propose removing the cron job that updates the version on trunk, and then check in this patch. For release branches, we can keep the cron job, but just tell it to rewrite bfd/version.h. I believe this is a simple change in the crontab -- the script will work just fine on this file. This also moves version.in and version.h into common/, to reflect their shared status; and updates gdbserver to use version.h besides. * common/create-version.sh: New file. * Makefile.in (version.c): Use bfd/version.h, common/version.in, create-version.sh.

[GDBserver] Multi-process + multi-arch This patch makes GDBserver support multi-process + biarch. Currently, if you're debugging more than one process at once with a single gdbserver (in extended-remote mode), then all processes must have the same architecture (e.g., 64-bit vs 32-bit). Otherwise, you see this: Added inferior 2 [Switching to inferior 2 [<null>] (<noexec>)] Reading symbols from /home/pedro/gdb/tests/main32...done. Temporary breakpoint 2 at 0x4004cf: main.

Even though the process was running a 32-bit program, GDBserver sent back to GDB a register set in 64-bit layout. A patch (http://sourceware.org/ml/gdb-patches/2012-11/msg00228.html) a while ago made GDB track a target_gdbarch per inferior, and as consequence, fetch a target description per-inferior. This patch is the GDBserver counterpart, that makes GDBserver keep track of each process'es XML target description and register layout. So in the example above, GDBserver will send the correct register set in 32-bit layout to GDB. A new "struct target_desc" object (tdesc for short) is added, that holds the target description and register layout information about each process. Each `struct process_info' holds a pointer to a target description. The regcache also gains a pointer to a target description, mainly for convenience, and parallel with GDB (and possible future support for programs that flip processor modes). The low target's arch_setup routines are responsible for setting the process'es correct tdesc. This isn't that much different to how things were done before, except that instead of detecting the inferior process'es architecture and calling the corresponding init_registers_FOO routine, which would change the regcache layout globals and recreate the threads' regcaches, the regcache.c globals are gone, and the init_registers_$BAR routines now each initialize a separate global struct target_desc object (one for each arch variant GDBserver supports), and so all the init_registers_$BAR routines that are built into GDBserver are called early at GDBserver startup time (similarly to how GDB handles its built-in target descriptions), and then the arch_setup routine is responsible for making process_info->tdesc point to one of these target description globals. The regcache module is all parameterized to get the regcache's layout from the tdesc object instead of the old register_bytes, etc. globals. The threads' regcaches are now created lazily. The old scheme where we created each of them when we added a new thread doesn't work anymore, because we add the main thread/lwp before we see it stop for the first time, and it is only when we see the thread stop for the first time that we have a chance of determining the inferior's architecture (through the_low_target.arch_setup). Therefore when we add the main thread we don't know which architecture/tdesc its regcache should have. This patch makes the gdb.multi/multi-arch.exp test now pass against (extended-remote) GDBserver. It currently fails, without this patch. The IPA also uses the regcache, so it gains a new global struct target_desc pointer, which points at the description of the process it is loaded in. Re. the linux-low.c & friends changes. Since the register map etc. may differ between processes (64-bit vs 32-bit) etc., the linux_target_ops num_regs, regmap and regset_bitmap data fields are no longer sufficient. A new method is added in their place that returns a pointer to a new struct that includes all info linux-low.c needs to access registers of the current inferior. The patch/discussion that originally introduced linux-low.c:disabled_regsets mentions that the disabled_regsets set may be different per mode (in a biarch setup), and indeed that is cleared whenever we start a new (first) inferior, so that global is moved as well behind the new `struct regs_info'. On the x86 side: I simply replaced the i387-fp.c:num_xmm_registers global with a check for 64-bit or 32-bit process, which is equivalent to how the global was set. This avoided coming up with some more general mechanism that would work for all targets that use this module (GNU/Linux, Windows, etc.).

[GDBserver] Multi-process + multi-arch This patch makes GDBserver support multi-process + biarch. Currently, if you're debugging more than one process at once with a single gdbserver (in extended-remote mode), then all processes must have the same architecture (e.g., 64-bit vs 32-bit). Otherwise, you see this: Added inferior 2 [Switching to inferior 2 [<null>] (<noexec>)] Reading symbols from /home/pedro/gdb/tests/main32...done. Temporary breakpoint 2 at 0x4004cf: main.

Even though the process was running a 32-bit program, GDBserver sent back to GDB a register set in 64-bit layout. A patch (http://sourceware.org/ml/gdb-patches/2012-11/msg00228.html) a while ago made GDB track a target_gdbarch per inferior, and as consequence, fetch a target description per-inferior. This patch is the GDBserver counterpart, that makes GDBserver keep track of each process'es XML target description and register layout. So in the example above, GDBserver will send the correct register set in 32-bit layout to GDB. A new "struct target_desc" object (tdesc for short) is added, that holds the target description and register layout information about each process. Each `struct process_info' holds a pointer to a target description. The regcache also gains a pointer to a target description, mainly for convenience, and parallel with GDB (and possible future support for programs that flip processor modes). The low target's arch_setup routines are responsible for setting the process'es correct tdesc. This isn't that much different to how things were done before, except that instead of detecting the inferior process'es architecture and calling the corresponding init_registers_FOO routine, which would change the regcache layout globals and recreate the threads' regcaches, the regcache.c globals are gone, and the init_registers_$BAR routines now each initialize a separate global struct target_desc object (one for each arch variant GDBserver supports), and so all the init_registers_$BAR routines that are built into GDBserver are called early at GDBserver startup time (similarly to how GDB handles its built-in target descriptions), and then the arch_setup routine is responsible for making process_info->tdesc point to one of these target description globals. The regcache module is all parameterized to get the regcache's layout from the tdesc object instead of the old register_bytes, etc. globals. The threads' regcaches are now created lazily. The old scheme where we created each of them when we added a new thread doesn't work anymore, because we add the main thread/lwp before we see it stop for the first time, and it is only when we see the thread stop for the first time that we have a chance of determining the inferior's architecture (through the_low_target.arch_setup). Therefore when we add the main thread we don't know which architecture/tdesc its regcache should have. This patch makes the gdb.multi/multi-arch.exp test now pass against (extended-remote) GDBserver. It currently fails, without this patch. The IPA also uses the regcache, so it gains a new global struct target_desc pointer, which points at the description of the process it is loaded in. Re. the linux-low.c & friends changes. Since the register map etc. may differ between processes (64-bit vs 32-bit) etc., the linux_target_ops num_regs, regmap and regset_bitmap data fields are no longer sufficient. A new method is added in their place that returns a pointer to a new struct that includes all info linux-low.c needs to access registers of the current inferior. The patch/discussion that originally introduced linux-low.c:disabled_regsets mentions that the disabled_regsets set may be different per mode (in a biarch setup), and indeed that is cleared whenever we start a new (first) inferior, so that global is moved as well behind the new `struct regs_info'. On the x86 side: I simply replaced the i387-fp.c:num_xmm_registers global with a check for 64-bit or 32-bit process, which is equivalent to how the global was set. This avoided coming up with some more general mechanism that would work for all targets that use this module (GNU/Linux, Windows, etc.).

[GDBserver] Multi-process + multi-arch This patch makes GDBserver support multi-process + biarch. Currently, if you're debugging more than one process at once with a single gdbserver (in extended-remote mode), then all processes must have the same architecture (e.g., 64-bit vs 32-bit). Otherwise, you see this: Added inferior 2 [Switching to inferior 2 [<null>] (<noexec>)] Reading symbols from /home/pedro/gdb/tests/main32...done. Temporary breakpoint 2 at 0x4004cf: main.

Even though the process was running a 32-bit program, GDBserver sent back to GDB a register set in 64-bit layout. A patch (http://sourceware.org/ml/gdb-patches/2012-11/msg00228.html) a while ago made GDB track a target_gdbarch per inferior, and as consequence, fetch a target description per-inferior. This patch is the GDBserver counterpart, that makes GDBserver keep track of each process'es XML target description and register layout. So in the example above, GDBserver will send the correct register set in 32-bit layout to GDB. A new "struct target_desc" object (tdesc for short) is added, that holds the target description and register layout information about each process. Each `struct process_info' holds a pointer to a target description. The regcache also gains a pointer to a target description, mainly for convenience, and parallel with GDB (and possible future support for programs that flip processor modes). The low target's arch_setup routines are responsible for setting the process'es correct tdesc. This isn't that much different to how things were done before, except that instead of detecting the inferior process'es architecture and calling the corresponding init_registers_FOO routine, which would change the regcache layout globals and recreate the threads' regcaches, the regcache.c globals are gone, and the init_registers_$BAR routines now each initialize a separate global struct target_desc object (one for each arch variant GDBserver supports), and so all the init_registers_$BAR routines that are built into GDBserver are called early at GDBserver startup time (similarly to how GDB handles its built-in target descriptions), and then the arch_setup routine is responsible for making process_info->tdesc point to one of these target description globals. The regcache module is all parameterized to get the regcache's layout from the tdesc object instead of the old register_bytes, etc. globals. The threads' regcaches are now created lazily. The old scheme where we created each of them when we added a new thread doesn't work anymore, because we add the main thread/lwp before we see it stop for the first time, and it is only when we see the thread stop for the first time that we have a chance of determining the inferior's architecture (through the_low_target.arch_setup). Therefore when we add the main thread we don't know which architecture/tdesc its regcache should have. This patch makes the gdb.multi/multi-arch.exp test now pass against (extended-remote) GDBserver. It currently fails, without this patch. The IPA also uses the regcache, so it gains a new global struct target_desc pointer, which points at the description of the process it is loaded in. Re. the linux-low.c & friends changes. Since the register map etc. may differ between processes (64-bit vs 32-bit) etc., the linux_target_ops num_regs, regmap and regset_bitmap data fields are no longer sufficient. A new method is added in their place that returns a pointer to a new struct that includes all info linux-low.c needs to access registers of the current inferior. The patch/discussion that originally introduced linux-low.c:disabled_regsets mentions that the disabled_regsets set may be different per mode (in a biarch setup), and indeed that is cleared whenever we start a new (first) inferior, so that global is moved as well behind the new `struct regs_info'. On the x86 side: I simply replaced the i387-fp.c:num_xmm_registers global with a check for 64-bit or 32-bit process, which is equivalent to how the global was set. This avoided coming up with some more general mechanism that would work for all targets that use this module (GNU/Linux, Windows, etc.).

range stepping: gdbserver (x86 GNU/Linux) This patch adds support for range stepping to GDBserver, teaching it about vCont;r. It'd be easy to enable this for all hardware single-step targets without needing the linux_target_ops hook, however, at least PPC needs special care, due to the fact that PPC atomic sequences can't be hardware single-stepped through, a thing which GDBserver doesn't know about.

gdbserver/lynx178: spurious SIG61 signal when resuming inferior. On ppc-lynx178, resuming the execution of a program after hitting a breakpoint sometimes triggers a spurious SIG61 event: (gdb) cont Continuing. Program received signal SIG61, Real-time event 61. [Switching to Thread 39] 0x10002324 in a_test.task1 (<_task>=0x3ffff774) at a_test.adb:30 30 select -- Task 1 From this point on, continuing again lets the signal kill the program. Using "signal 0" or configuring GDB to discard the signal does not help either, as the program immediately reports the same signal again. What happens is the following: - GDB sends a single-step order to gdbserver: $vCont;s:31 This tells GDBserver to do a step using thread 0x31=49. GDBserver does the step, and thread 49 receives the SIGTRAP indicating that the step has finished. - GDB then sends a "continue", but this time does not specify which thread to continue: $vCont;c GDBserver uses an arbitrary thread's ptid to resume the program's execution (the current_inferior's ptid was chosen for that). See lynx-low.c:lynx_resume: if (ptid_equal (ptid, minus_one_ptid)) ptid = thread_to_gdb_id (current_inferior); So far on all LynxOS platforms, this has been good enough. But not so on LynxOS 178. If the ptid used to resume the execution is not the same as the thread that did the step, we get the weird signal. This patch fixes the problem by saving the ptid of the thread that last caused an event, received during a call to waitpid. The ptid is saved in per-process private data. gdb/gdbserver/ChangeLog: * lynx-low.c (struct process_info_private): New type. (lynx_add_process): New function.

Linux: No need to set ptrace event options in fork/clone children. Oleg Nesterov told me that the Linux kernel copies the parent's ptrace options to fork/clone children, so there's no need for GDB to do that manually. I was actually a bit surprised, since I thought the ptracer had to always set the ptrace options itself, and GDB is indeed calling PTRACE_SETOPTIONS for each new fork child, if it'll stay attached. Looking at the history of that code, I found that is was actually I who added that set-ptrace-options-in-children bit, back in http://sourceware.org/ml/gdb-patches/2009-05/msg00656.html. But, honestly, I don't recall why I needed that. I think I may have just blindly believed it was necessary. I then looked back at the history of all the PTRACE_SETOPTIONS code we have, and found that gdb never did copy the ptrace options before my patch. But, when gdbserver learnt to use PTRACE_EVENT_CLONE, at http://sourceware.org/ml/gdb-patches/2007-10/msg00547.html, it was made to do 'ptrace (PTRACE_SETOPTIONS, new_pid, 0, PTRACE_O_TRACECLONE)' for all new clones. Hmmm. But, GDB itself never did that, so it can't really ever have been necessary, I believe, otherwise GDB should have been doing it too. (GDBserver doesn't support following forks, and so naturally doesn't do any PTRACE_SETOPTIONS on fork children.) So this patch removes the -I believe- unnecessary ptrace syscalls. Tested on x86_64 Fedora 17, native/gdbserver, and on x86_64 RHEL5 native/gdbserver (Linux 2.6.18, I think a ptrace-on-utrace kernel).

Consistent use of (C) after "Copyright". While writing the previous patch, I noticed that we're not consistent with the (C) in the copyright header. The maintainers manual prefers having it, though also says it's optional. We have over 10x more files with (C) than without in gdb's code, so I spent a few minutes grepping and fixing. Funny enough, the testsuite has it backwards.
