A purely virtual class containing functions from gdb/regcache.h Both the gdb regcache structures and gdbserver regcache inherit directly from reg_buffer_common.

2018-06-10Remove use of queue from remote.cTom Tromey2-228/+108
This removes a use of the queue data structure (common/queue.h) from remote.c. The queue is replaced with a std::vector. A queue was not needed, as the code never de-queued items. This removes quite a bit of boilerplate code, mostly involved with marshalling arguments to be passed through the queue iterator. Tested by the buildbot. gdb/ChangeLog 2018-06-10 Tom Tromey <tom@tromey.com> * remote.c (stop_reply_p): Remove typedef. Don't declare queue. (class remote_state) <stop_reply_queue>: Now std::vector.

2018-06-10Remove cleanups from record-full.cTom Tromey2-269/+290
This removes cleanups from record-full.c. In this case, the cleanups were only ever run when an exception was thrown. So, I replaced these with try/catch, rather than introduce a new specialized RAII type. Tested by the buildbot. gdb/ChangeLog 2018-06-10 Tom Tromey <tom@tromey.com> * record-full.c (record_full_arch_list_cleanups): Remove. (record_full_message): Use try/catch.

2018-06-10Remove a VEC from record-full.cTom Tromey2-44/+45
This replaces a VEC in record-full.c with a std::vector. This version of the patch also catches a memory leak in the original code noticed by Simon. Tested by the buildbot. gdb/ChangeLog 2018-06-10 Tom Tromey <tom@tromey.com> * record-full.c (record_full_breakpoint_p): Remove typedef. Don't declare VEC. Add constructor. <in_target_beneath>: Now bool. (record_full_breakpoints): Now a std::vector, static. (record_full_sync_record_breakpoints) (record_full_init_record_breakpoints) (record_full_target::insert_breakpoint) (record_full_target::remove_breakpoint): Update. Don't use XNEW.

2018-06-10Fix some missed "beneath" conversionsTom Tromey6-12/+25
The buildbot pointed out that arm-linux-nat.c was not properly using "beneath" as a method. A search showed a few more places with this issue. Tested by the buildbot, though of course this only checked arm-linux-nat.c. Nevertheless I'm checking this in under the obvious rule. gdb/ChangeLog 2018-06-10 Tom Tromey <tom@tromey.com> * procfs.c (procfs_target::xfer_partial): Use "beneath" as a method. * nto-procfs.c (nto_procfs_target::xfer_partial): Use "beneath" as a method. * go32-nat.c (go32_nat_target::xfer_partial): Use "beneath" as a method. * arm-linux-nat.c (arm_linux_nat_target::read_description): Use "beneath" as a method. * arm-fbsd-nat.c (arm_fbsd_nat_target::read_description): Use "beneath" as a method.
2018-06-10Remove cleanups from tracefile.cTom Tromey2-32/+25
This removes cleanups from tracefile.c, by introducing a unique_ptr specialization. This code could be made even simpler via a deeper C++-ification, but I have not attempted that. Tested by the buildbot. gdb/ChangeLog 2018-06-10 Tom Tromey <tom@tromey.com> * tracefile.c (struct trace_file_writer_deleter): New. <operator()>: Rename from trace_file_writer_xfree. (trace_file_writer_up): New typedef. (tsave_command, trace_save_tfile, trace_save_ctf): Update.
2018-06-09Use std::unique_ptr in reg_bufferSimon Marchi3-16/+21
Using std::unique_ptr allows to remove the manual xfree in the destructor. If I understand correctly, using the () after the new operator will make sure the allocated objects will be value initialized, which for scalars means they are zero-initialized. So it should have the same behavior as XCNEWVEC. gdb/ChangeLog: * regcache.h (reg_buffer) <~reg_buffer>: Use default destructor. <m_registers, m_register_status>: Change type to std::unique_ptr. * regcache.c (reg_buffer::reg_buffer): Use new instead of XCNEWVEC.
2018-06-09Change type of reg_buffer::m_register_status to register_statusSimon Marchi4-9/+23
The type of reg_buffer::m_register_status is an array of signed char, probably to ensure that each element takes up only one byte. Instead, since we use C++11, we can force the underlying type of register_status to be signed char and use the enum type. gdb/ChangeLog: * common/common-regcache.h (enum register_status): Add underlying type "signed char". * regcache.h (reg_buffer) <m_register_status>: Change type to register_status *. * regcache.c (reg_buffer::reg_buffer): Alocate arrays of register_status instead of signed char. (reg_buffer::save): Use REG_UNKNOWN instead of 0. (reg_buffer::get_register_status): Remove cast. (readable_regcache::raw_read): Remove cast. (readable_regcache::cooked_read): Remove cast.

2018-06-09Remove use of queue.h from gdbserver/event-loop.cTom Tromey2-22/+20
This removes a use of queue.h from gdbserver/event-loop.c, replacing it with std::queue. I was not completely sure whether std::queue is even that useful. Perhaps plain std::list could be used just as easily. Tested by the buildbot. gdb/gdbserver/ChangeLog 2018-06-09 Tom Tromey <tom@tromey.com> * event-loop.c (gdb_event, gdb_event_p): Remove typedefs. Don't declare queue. (event_queue): Use std::queue. (gdb_event_xfree): Remove. (initialize_event_loop, process_event, wait_for_event): Update.
2018-06-09Remove two more uses of make_cleanup_closeTom Tromey2-18/+17
This removes two more uses of make_cleanup_close, replacing them with relatively straightforward uses of scoped_fd. Tested by the buildbot. gdb/ChangeLog 2018-06-09 Tom Tromey <tom@tromey.com> * source.c (reverse_search_command, forward_search_command): Use scoped_fd.
2018-06-09Remove a VEC from serial.cTom Tromey2-9/+9
This replaces a VEC in serial.c with a std::vector. Tested by the buildbot. gdb/ChangeLog 2018-06-09 Tom Tromey <tom@tromey.com> * serial.c (serial_ops_p): Remove typedef. Don't declare VEC. (serial_ops_list): Now static, std::vector. (serial_interface_lookup, serial_add_interface): Update.
2018-06-09Remove a VEC from dwarf2read.cTom Tromey3-10/+11
This removes a VEC from dwarf2read.c, replacing it with a std::vector. Tested by the buildbot. gdb/ChangeLog 2018-06-09 Tom Tromey <tom@tromey.com> * dwarf2read.c (process_cu_includes): Update. (process_full_comp_unit): Update. * dwarf2read.h (struct dwarf2_per_objfile) <just_read_cus>: Now a std::vector.

2018-06-08Make gdbreplay use more common routinesPedro Alves3-37/+52
This makes gdbreplay share a bit more code with gdbserver, and paves the way to share more in future. Including common-defs.h pulls in defines and headers that gdb and gdbserver assume are always defined/available too, such as for example _(), ansidecl.h or a set of system headers. Including that revealed (static vs extern conflict) gdbreplay had a local copy of perror_with_name (which exited directly instead of throwing an error). So I removed gdbreplay's local copy, and then added enough .o files until gdbreplay linked successfully. Also, use xstrdup instead of strdup. gdb/gdbserver/ChangeLog: 2018-06-08 Pedro Alves <palves@redhat.com> * Makefile.in (GDBREPLAY_OBS): Add common/cleanups.o, common/common-exceptions.o, common/common-utils.o, common/errors.o, common/print-utils.o and utils.o. * gdbreplay.c: Include "common-defs.h" instead of the two 'config.h's here. Don't include stdio.h, errno.h, stdlib.h, string.h or alloca.h. (perror_with_name): Delete. (remote_open): Use xstrdup instead of strdup. (main): Rename to ... (captured_main): ... this. (main): New.

2018-06-08linux: Add maintenance commands to test libthread_dbGary Benson8-0/+524
This commit adds two new commands which may be used to test thread debugging libraries used by GDB: * "maint check libthread-db" tests the thread debugging library GDB is using for the current inferior. * "maint set/show check-libthread-db" selects whether libthread_db tests should be run automatically as libthread_db is auto-loaded. The default is to not run tests automatically. The test itself is a basic integrity check exercising all libthread_db functions used by GDB on GNU/Linux systems. By extension this also exercises the proc_service functions provided by GDB that libthread_db uses. This functionality is useful for NPTL developers and libthread_db developers. It could also prove useful investigating bugs reported against GDB where the thread debugging library or GDB's proc_service layer is suspect. gdb/ChangeLog: * linux-thread-db.c (valprint.h): New include. (struct check_thread_db_info): New structure. (check_thread_db_on_load, tdb_testinfo): New static globals. (check_thread_db, check_thread_db_callback): New functions.

2018-06-08Define various symbols conditionally in shared librariesAlan Modra268-2108/+2241
The values of symbols in shared libraries like _end, _edata, and __bss_start are generally not that useful outside of the shared library. This patch defines them conditionally with PROVIDE, since a shared library might need the local value. An example is glibc ld.so local access to "_begin", "_etext" and "_end".

2018-06-07Introduce class target_stackPedro Alves3-62/+119
Currently, the target stack is represented by a singly linked list, with target_ops having a pointer to the target beneath. This poses a problem for multi-process / multi-target debugging. In that case, we will naturally want multiple instances of target stacks. E.g., one stack for inferior 1 which is debugging a core file, and another target stack for inferior 2 which is debugging a remote process. The problem then is in finding a target's "beneath" target, if we consider that for some target_ops types, we'll be sharing a single target_ops instance between several inferiors. For example, so far, I found no need to have multiple instances of the spu_multiarch_target / exec_target / dummy_target targets. Thus this patch, which changes the target stack representation to an array of pointers. For now, there's still a single global instance of this new target_stack class, though further down in the multi-target work, each inferior will have its own instance. gdb/ChangeLog: 2018-06-07 Pedro Alves <palves@redhat.com> * target.h (target_ops) <beneath>: Now a method.

2018-06-07target_ops::beneath -> target_ops::beneath()Pedro Alves10-747/+747
This changes target_ops::beneath from a pointer to a method, and adjusts all references throughout. The idea here is to make it easier to change the target stack representation from an intrusive singly linked list to something else without leaking implementation details throughout. The commit does not change the representation yet, that will be done in a following patch. That is why a new target_ops::m_beneath field appears here. That new field isn't really documented properly or made private, simply because it will be removed shortly. Note that target_ops::beneath() is essentially the same as the current find_target_beneath routine. The following patch will eliminate the latter. gdb/ChangeLog: 2018-06-07 Pedro Alves <palves@redhat.com> * target.h (target_ops) <beneath>: Now a method. All references updated.

2018-06-07target_stack -> current_top_target() throughoutPedro Alves49-305/+378
The recent C++ification of target_ops replaced references to the old "current_target" squashed target throughout with references to a "target_stack" pointer. I had picked the "target_stack" name very early in the multi-target work, and managed to stick with it, even though it's a bit of a misnomer, since it isn't really a "target stack" object, but a pointer into the current top target in the stack. As I'm splitting more pieces off of the multi-target branch, I've come to think that it's better to rename it now. A following patch will introduce a new class to represent a target stack, and "target_stack" would be _its_ ideal name. (In the branch, the class is called a_target_stack to work around the clash.) Thus this commit renames target_stack to current_top_target and replaces all references throughout. Also, while at it, current_top_target is made a function instead of a pointer, to make it possible to change its internal implementation without leaking implementation details out. In a couple patches, the implementation of the function will change to refer to a target stack object, and then further down the multi-target work, it'll change again to find the right target stack for the current inferior. gdb/ChangeLog: 2018-06-07 Pedro Alves <palves@redhat.com> * target.h (target_stack): Delete.
