Add support for catching system calls to native FreeBSD targets. All platforms on FreeBSD use a shared system call table, so use a single XML file to describe the system calls available on each FreeBSD platform. Recent versions of FreeBSD include the identifier of the current system call when reporting a system call entry or exit event in the ptrace_lwpinfo structure obtained via PT_LWPINFO in fbsd_wait. As such, FreeBSD native targets do not use the gdbarch method to fetch the system call code. In addition, FreeBSD register sets fetched via ptrace do not include an equivalent of 'orig_rax' (on amd64 for example), so the system call code cannot be extracted from the available registers during a system call exit. However, GDB assumes that system call catch points are not supported if the gdbarch method is not present. As a workaround, FreeBSD ABIs install a dummy gdbarch method that throws an internal_error if it is ever invoked. gdb/ChangeLog: * configure.ac: Check for support for system call LWP fields on FreeBSD. * config.in, configure: Rebuild. * data-directory/Makefile.in (SYSCALLS_FILES): Add freebsd.xml. * fbsd-nat.c (fbsd_wait) [HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE]: Report system call events. [HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE] (fbsd_set_syscall_catchpoint): New function. (fbsd_nat_add_target) [HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE]: Set "to_set_syscall_catchpoint" to "fbsd_set_syscall_catchpoint". * fbsd-tdep.c: Include xml-syscall.h (fbsd_get_syscall_number): New function. (fbsd_init_abi): Set XML system call file name. Add "get_syscall_number" gdbarch method. * syscalls/freebsd.xml: New file.

Change pid_to_str to return std::string 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.

Change pid_to_str to return std::string 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.

Split size in regset section iterators In the existing code, when using the regset section iteration functions, the size parameter is used in different ways. With collect, size is used to create the buffer in which to write the regset. (see linux-tdep.c::linux_collect_regset_section_cb). With supply, size is used to confirm the existing regset is the correct size. If REGSET_VARIABLE_SIZE is set then the regset can be bigger than size. Effectively, size is the minimum possible size of the regset. (see corelow.c::get_core_register_section). There are currently no targets with both REGSET_VARIABLE_SIZE and a collect function. In SVE, a corefile can contain one of two formats after the header, both of which are different sizes. However, when writing a core file, we always want to write out the full bigger size.

Split size in regset section iterators In the existing code, when using the regset section iteration functions, the size parameter is used in different ways. With collect, size is used to create the buffer in which to write the regset. (see linux-tdep.c::linux_collect_regset_section_cb). With supply, size is used to confirm the existing regset is the correct size. If REGSET_VARIABLE_SIZE is set then the regset can be bigger than size. Effectively, size is the minimum possible size of the regset. (see corelow.c::get_core_register_section). There are currently no targets with both REGSET_VARIABLE_SIZE and a collect function. In SVE, a corefile can contain one of two formats after the header, both of which are different sizes. However, when writing a core file, we always want to write out the full bigger size.

s/get_regcache_arch (regcache)/regcache->arch ()/g This patches removes get_regcache_arch, and use regache->arch () instead.

Per-inferior thread list, thread ranges/iterators, down with ALL_THREADS, etc. 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.

Per-inferior thread list, thread ranges/iterators, down with ALL_THREADS, etc. 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.

Add support for 'info proc files' on FreeBSD core dumps. Walk the list of struct kinfo_file objects in the NT_FREEBSD_PROCSTAT_FILES core dump note outputting a description of each open file descriptor.

Add support for catching system calls to native FreeBSD targets. All platforms on FreeBSD use a shared system call table, so use a single XML file to describe the system calls available on each FreeBSD platform. Recent versions of FreeBSD include the identifier of the current system call when reporting a system call entry or exit event in the ptrace_lwpinfo structure obtained via PT_LWPINFO in fbsd_wait. As such, FreeBSD native targets do not use the gdbarch method to fetch the system call code. In addition, FreeBSD register sets fetched via ptrace do not include an equivalent of 'orig_rax' (on amd64 for example), so the system call code cannot be extracted from the available registers during a system call exit. However, GDB assumes that system call catch points are not supported if the gdbarch method is not present. As a workaround, FreeBSD ABIs install a dummy gdbarch method that throws an internal_error if it is ever invoked. gdb/ChangeLog: * configure.ac: Check for support for system call LWP fields on FreeBSD. * config.in, configure: Rebuild. * data-directory/Makefile.in (SYSCALLS_FILES): Add freebsd.xml. * fbsd-nat.c (fbsd_wait) [HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE]: Report system call events.

(fbsd_nat_add_target) [HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE]: Set "to_set_syscall_catchpoint" to "fbsd_set_syscall_catchpoint". * fbsd-tdep.c: Include xml-syscall.h (fbsd_get_syscall_number): New function. (fbsd_init_abi): Set XML system call file name. Add "get_syscall_number" gdbarch method. * syscalls/freebsd.xml: New file.

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

fbsd_get_syscall_number (struct gdbarch *gdbarch, thread_info *thread)
Add support for catching system calls to native FreeBSD targets. All platforms on FreeBSD use a shared system call table, so use a single XML file to describe the system calls available on each FreeBSD platform. Recent versions of FreeBSD include the identifier of the current system call when reporting a system call entry or exit event in the ptrace_lwpinfo structure obtained via PT_LWPINFO in fbsd_wait. As such, FreeBSD native targets do not use the gdbarch method to fetch the system call code. In addition, FreeBSD register sets fetched via ptrace do not include an equivalent of 'orig_rax' (on amd64 for example), so the system call code cannot be extracted from the available registers during a system call exit. However, GDB assumes that system call catch points are not supported if the gdbarch method is not present. As a workaround, FreeBSD ABIs install a dummy gdbarch method that throws an internal_error if it is ever invoked. gdb/ChangeLog: * configure.ac: Check for support for system call LWP fields on FreeBSD. * config.in, configure: Rebuild. * data-directory/Makefile.in (SYSCALLS_FILES): Add freebsd.xml. * fbsd-nat.c (fbsd_wait) [HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE]: Report system call events. [HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE] (fbsd_set_syscall_catchpoint): New function. (fbsd_nat_add_target) [HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE]: Set "to_set_syscall_catchpoint" to "fbsd_set_syscall_catchpoint". * fbsd-tdep.c: Include xml-syscall.h (fbsd_get_syscall_number): New function. (fbsd_init_abi): Set XML system call file name. Add "get_syscall_number" gdbarch method. * syscalls/freebsd.xml: New file.

Add support for catching system calls to native FreeBSD targets. All platforms on FreeBSD use a shared system call table, so use a single XML file to describe the system calls available on each FreeBSD platform. Recent versions of FreeBSD include the identifier of the current system call when reporting a system call entry or exit event in the ptrace_lwpinfo structure obtained via PT_LWPINFO in fbsd_wait. As such, FreeBSD native targets do not use the gdbarch method to fetch the system call code. In addition, FreeBSD register sets fetched via ptrace do not include an equivalent of 'orig_rax' (on amd64 for example), so the system call code cannot be extracted from the available registers during a system call exit. However, GDB assumes that system call catch points are not supported if the gdbarch method is not present. As a workaround, FreeBSD ABIs install a dummy gdbarch method that throws an internal_error if it is ever invoked. gdb/ChangeLog: * configure.ac: Check for support for system call LWP fields on FreeBSD. * config.in, configure: Rebuild. * data-directory/Makefile.in (SYSCALLS_FILES): Add freebsd.xml. * fbsd-nat.c (fbsd_wait) [HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE]: Report system call events. [HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE] (fbsd_set_syscall_catchpoint): New function. (fbsd_nat_add_target) [HAVE_STRUCT_PTRACE_LWPINFO_PL_SYSCALL_CODE]: Set "to_set_syscall_catchpoint" to "fbsd_set_syscall_catchpoint". * fbsd-tdep.c: Include xml-syscall.h (fbsd_get_syscall_number): New function. (fbsd_init_abi): Set XML system call file name. Add "get_syscall_number" gdbarch method. * syscalls/freebsd.xml: New file.
