2019-09-20Remove Cell Broadband Engine debugging supportUlrich Weigand1-20/+0
This patch implements removal of Cell/B.E. support, including - Support for the spu-*-* target - Support for native stand-alone SPU debugging - Support for integrated debugging of combined PPU/SPU applications - Remote debugging (gdbserver) support for all the above. The patch also removes the TARGET_OBJECT_SPU target object type, as this is available only on Cell/B.E. targets, including - Native Linux support - Core file support (including core file generation) - Remote target support, including removal of the qXfer:spu:read and qXfer:spu:write remote protocal packets and associated support in gdbserver. gdb/ChangeLog 2019-09-20 Ulrich Weigand <uweigand@de.ibm.com> * NEWS: Mention that Cell/B.E. debugging support was removed. * MAINTAINERS: Remove spu target. * config/djgpp/fnchange.lst: Remove entries for removed files. * Makefile.in (ALL_TARGET_OBS): Remove solib-spu.o, spu-multiarch.o, and spu-tdep.o.

2019-08-15Replace write_inferior_memory with target_write_memoryTom Tromey1-1/+1
target_write_memory is just a simple wrapper for write_inferior_memory. Because target_write_memory is needed for gdbsupport, and because gdb uses the name "target_write_memory" everywhere, this patch renames write_inferior_memory and removes the wrapper. I think this brings gdb and gdbserver slightly more in sync. gdb/gdbserver/ChangeLog 2019-08-15 Tom Tromey <tromey@adacore.com> * tracepoint.c (write_inferior_data_pointer) (write_inferior_integer, write_inferior_int8) (write_inferior_uinteger, m_tracepoint_action_download) (r_tracepoint_action_download, x_tracepoint_action_download) (l_tracepoint_action_download, clear_inferior_trace_buffer) (download_agent_expr, download_tracepoint_1) (download_trace_state_variables, upload_fast_traceframes): Update. * server.c (gdb_write_memory): Update. * remote-utils.c (relocate_instruction): Update. * proc-service.c (ps_pdwrite): Update. * mem-break.c (remove_memory_breakpoint) (delete_fast_tracepoint_jump, set_fast_tracepoint_jump) (uninsert_fast_tracepoint_jumps_at) (reinsert_fast_tracepoint_jumps_at): Update. * linux-x86-low.c (append_insns) (i386_install_fast_tracepoint_jump_pad) (amd64_write_goto_address, i386_write_goto_address): Update. * linux-s390-low.c (append_insns, s390_write_goto_address): Update. * linux-ppc-low.c (ppc_relocate_instruction) (ppc_install_fast_tracepoint_jump_pad, emit_insns) (ppc_write_goto_address): Update. * linux-aarch64-low.c (append_insns): Update. * target.h (struct target_ops): Update.

2019-07-09Rename common to gdbsupportTom Tromey1-15/+15
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty. Tested by the buildbot. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

2019-06-04Introduce and use make_unique_xstrdupPedro Alves1-1/+1
Adds an utility function to make it shorter to write the common case of wrapping an xstrdup with a unique_xmalloc_ptr, and uses it throughout. Note: I tried to put this in common/common-utils.h near skip_spaces, etc. but that is included in common/common-defs.h before common/gdb_unique_ptr.h is included, so it would fail to compile because gdb::unique_xmalloc_ptr isn't defined at that point yet. I tried moving the gdb_unique_ptr.h inclusion before common-utils.h, but that doesn't work because gdb_unique_ptr.h depends on common-utils.h for xfree. gdb/ChangeLog: 2019-06-04 Pedro Alves <palves@redhat.com> * common/gdb_unique_ptr.h (make_unique_xstrdup): New. * ada-lang.c (catch_ada_completer): Use make_unique_xstrdup. * breakpoint.c (condition_completer): Likewise. * cli/cli-dump.c (scan_expression): Likewise. * common/filestuff.c (mkdir_recursive): Likewise. * common/gdb_tilde_expand.c (gdb_tilde_expand_up) * common/pathstuff.c (gdb_realpath, gdb_realpath_keepfile) (gdb_abspath): Likewise. * compile/compile-cplus-types.c (compile_cplus_instance::decl_name): Likewise. * completer.c (complete_explicit_location): (signal_completer, reg_or_group_completer_1): Likewise. * cp-support.c (cp_remove_params_if_any): Likewise. * fbsd-tdep.c (fbsd_core_vnode_path): Likewise. * guile/scm-safe-call.c (gdbscm_safe_eval_string): Likewise. * infcmd.c (strip_bg_char): Likewise. * linespec.c (copy_token_string): Likewise. * mi/mi-main.c (output_cores): Likewise. * psymtab.c (psymtab_search_name): * symfile.c (test_set_ext_lang_command): Likewise. * target.c (target_fileio_read_stralloc): Likewise. * tui/tui-regs.c (tui_reggroup_completer): Likewise. * value.c (complete_internalvar): Likewise. gdb/gdbserver/ChangeLog: 2019-06-04 Pedro Alves <palves@redhat.com> * server.c (captured_main): Use make_unique_xstrdup.

2019-04-17gdbserver: Move remote_debug to a single placeAlan Hayward1-2/+0
A comment in debug.h (written in 2014) states: "We declare debug format variables here, and debug_threads but no other debug content variables (e.g., not remote_debug) because while this file is not currently used by IPA it may be some day, and IPA may have its own set of debug content variables". This has resulted in remote_debug being declared in many .c/.h files throughout gdbserver. It would be much simplier to define it one place. The most logical place to define it is in debug.h, surrounded by #define guards. If IPA is changed, then at that point the variable can be moved elsewhere. gdb/gdbserver/ChangeLog: * debug.c (remote_debug): Add definition. * debug.h (remote_debug): Add declaration. * hostio.c (remote_debug): Remove declaration. * remote-utils.c (struct ui_file): Likewise. (remote_debug): Likewise. * remote-utils.h (remote_debug): Likewise, * server.c (remote_debug): Remove definition.
2019-04-08Rename gdb exception typesTom Tromey1-6/+6
This renames the gdb exception types. The old types were only needed due to the macros in common-exception.h that are now gone. The intermediate layer of gdb_exception_RETURN_MASK_ALL did not seem needed, so this patch removes it entirely. gdb/ChangeLog 2019-04-08 Tom Tromey <tom@tromey.com> * common/common-exceptions.h (gdb_exception_RETURN_MASK_ALL): Remove.

2019-04-08Make exceptions use std::string and be self-managingTom Tromey1-6/+7
This changes the exception's "message" member to be a shared_ptr wrapping a std::string. This allows removing the stack of exception messages, because now exceptions will self-destruct when needed.

2019-04-05Use upper-case for metasyntactic in gdbserver helpTom Tromey1-2/+2
I noticed that "gdbserver --help" contains a few metasyntactic variables that aren't in upper-case. This patch fixes them to conform to the GNU standard. gdb/gdbserver/ChangeLog 2019-04-05 Tom Tromey <tromey@adacore.com> * server.c (gdbserver_usage): Use upper-case for metasyntactic variables.
2019-03-06Remove last cleanup from gdbserverTom Tromey1-5/+6
This removes the last cleanup from gdbserver, replacing it with SCOPE_EXIT. This could perhaps be done in a different way, but this approach was direct and obviously correct. 2019-03-06 Tom Tromey <tom@tromey.com> * server.c (detach_or_kill_for_exit_cleanup): Remove parameter. (captured_main): Use SCOPE_EXIT.
2019-02-07gdbserver: When attaching, add process before lwpsAlan Hayward1-0/+3
The recent BP/WP changes for AArch64 swapping the order in add_lwp() so that the process was added before the lwp. This was due to the lwp creation requiring the process data. This also needs changing in linux_attach(). Also add additional checks to make sure cannot attach to the same process twice. Add test case for this - do this by splitting attach.exp into distinct pass and error case sections. Fixes gdb.server/ext-attach.exp on Aarch64. gdb/gdbserver/ChangeLog: * linux-low.c (linux_attach): Add process before lwp. * server.c (attach_inferior): Check if already attached. gdb/testsuite/ChangeLog: * gdb.base/attach.exp: Add double attach test.

2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+1
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.
2018-11-29Fix use-after-free in gdbserverTom Tromey1-3/+7
-fsanitize=address pointed out a use-after-free in gdbserver. In particular, handle_detach could reference "process" after it was deleted by detach_inferior. Avoiding this also necessitated changing target_ops::join to take a pid rather than a process_info*. Tested by the buildbot using a few of the gdbserver builders. gdb/gdbserver/ChangeLog 2018-11-29 Tom Tromey <tom@tromey.com> * win32-low.c (win32_join): Take pid, not process. * target.h (struct target_ops) <join>: Change argument type.

2018-10-10Add parameter to allow enabling/disabling selftests via configureSergio Durigan Junior1-1/+1
This is a follow-up of: https://sourceware.org/ml/gdb-patches/2018-08/msg00347.html Instead of going throttle and always enabling our selftests (even in non-development builds), this patch is a bit more conservative and introduces a configure option ("--enable-unit-tests") that allows the user to choose whether she wants unit tests in the build or not. Note that the current behaviour is retained: if no option is provided, GDB will have selftests included in a development build, and will *not* have selftests included in a non-development build. The rationale for having this option is still the same: due to the many racy testcases and random failures we see when running the GDB testsuite, it is unfortunately not possible to perform a full test when one is building a downstream package. As the Fedora GDB maintainer and one of the Debian GDB uploaders, I feel like this situation could be improved by, at least, executing our selftests after the package has been built. This patch introduces no regressions to our build.

2018-07-11GDBserver: Don't assume a current process in D;PID implementation (PR gdb/23377)Pedro Alves1-18/+21
This fixes a gdb.base/multi-forks.exp regression with GDBserver. Git commit f2ffa92bbce9 ("gdb: Eliminate the 'stop_pc' global") caused the regression by exposing a latent bug in gdbserver. The bug is that GDBserver's implementation of the D;PID packet incorrectly assumes that the selected thread points to the process being detached. This happens via the any_persistent_commands call, which calls current_process: (gdb) bt #0 0x000000000040a57e in internal_error(char const*, int, char const*, ...) (file=0x4a53c0 "src/gdb/gdbserver/inferiors.c", line=212, fmt=0x4a539e "%s: Assertion `%s' failed.") at src/gdb/gdbserver/../common/errors.c:54 #1 0x0000000000420acf in current_process() () at src/gdb/gdbserver/inferiors.c:212 #2 0x00000000004226a0 in any_persistent_commands() () at gdb/gdbserver/mem-break.c:308 #3 0x000000000042cb43 in handle_detach(char*) (own_buf=0x6f0280 "D;62ea") at src/gdb/gdbserver/server.c:1210 #4 0x0000000000433af3 in process_serial_event() () at src/gdb/gdbserver/server.c:4055 #5 0x0000000000434878 in handle_serial_event(int, void*) (err=0, client_data=0x0) The "eliminate stop_pc" commit exposes the problem because before that commit, GDB's switch_to_thread always read the newly-selected thread's PC, and that would end up forcing GDBserver's selected thread to change accordingly as side effect. After that commit, GDB no longer reads the thread's PC, and GDBserver does not switch the thread. Fix this by removing the assumption from GDBserver. gdb/gdbserver/ChangeLog: 2018-07-11 Pedro Alves <palves@redhat.com> PR gdb/23377 * mem-break.c (any_persistent_commands): Add process_info parameter and use it instead of relying on the current process. Change return type to bool. * mem-break.h (any_persistent_commands): Add process_info parameter and change return type to bool. * server.c (handle_detach): Remove require_running_or_return call. Look up the process_info for the process we're about to detach. If not found, return back error to GDB. Adjust any_persistent_commands call to pass down a process pointer.

2018-03-01btrace, gdbserver: check btrace target pointersMarkus Metzger1-10/+28
By removing the supports_btrace gdbserver target method we relied on GDB trying to enable branch tracing and failing on the attempt. For targets that do not provide the btrace methods, however, an initial request from GDB for the branch trace configuration to detect whether gdbserver is already recording resulted in a protocol error. Have the btrace target methods throw a "Target does not suppor branch tracing" error and be prepared to handle exceptions in all functions that call btrace target methods. We therefore turn the target_* macros into static inline functions. Also remove the additional btrace target method checks that resulted in the above protocol error. Thanks to Maciej W. Rozycki <macro@mips.com> for reporting this. gdbserver/ * target.h (target_enable_btrace, target_disable_btrace) (target_read_btrace, target_read_btrace_conf): Turn macro into inline function. Throw error if target method is not defined. * server.c (handle_qxfer_btrace, handle_qxfer_btrace_conf): Remove check for btrace target method. Be prepared to handle exceptions from btrace target methods.
2018-02-28Change order of error message printed when gdbserver can't find CWDSergio Durigan Junior1-1/+1
I forgot to address Pedro's comment about my last patch and change the order of the message printed when getcwd returns NULL on gdbserver.

2018-02-28Make gdbserver work with filename-only binariesSergio Durigan Junior1-13/+40
Simon mentioned on IRC that, after the startup-with-shell feature has been implemented on gdbserver, it is not possible to specify a filename-only binary, like: $ gdbserver :1234 a.out /bin/bash: line 0: exec: a.out: not found During startup program exited with code 127. Exiting This happens on systems where the current directory "." is not listed in the PATH environment variable. Although including "." in the PATH variable is a possible workaround, this can be considered a regression because before startup-with-shell it was possible to use only the filename (due to reason that gdbserver used "exec*" directly). The idea of the patch is to verify if the program path provided by the user (or by the remote protocol) contains a directory separator character. If it doesn't, it means we're dealing with a filename-only binary, so we call "gdb_abspath" to properly expand it and transform it into a full path. Otherwise, we leave the program path untouched. This mimicks the behaviour seen on GDB (look at "openp" and "attach_inferior", for example). I am also submitting a testcase which exercises the scenario described above. This test requires gdbserver to be executed in a different CWD than the original, so I also created a helper function, "with_cwd" (on testsuite/lib/gdb.exp), which takes care of cd'ing into and out of the specified dir. Built and regtested on BuildBot, without regressions. gdb/ChangeLog: 2018-02-28 Sergio Durigan Junior <sergiodj@redhat.com> Simon Marchi <simon.marchi@polymtl.ca> * common/common-utils.c: Include "sys/stat.h".

2018-02-28Create new common/pathstuff.[ch]Sergio Durigan Junior1-0/+11
This commit moves the path manipulation routines found on utils.c to a new common/pathstuff.c, and updates the Makefile.in's accordingly. The routines moved are "gdb_realpath", "gdb_realpath_keepfile" and "gdb_abspath". This will be needed because gdbserver will have to call "gdb_abspath" on my next patch, which implements a way to expand the path of the inferior provided by the user in order to allow specifying just the binary name when starting gdbserver, like: $ gdbserver :1234 a.out With the recent addition of the startup-with-shell feature on gdbserver, this scenario doesn't work anymore if the user doesn't have the current directory listed in the PATH variable. I had to do a minor adjustment on "gdb_abspath" because we don't have access to "tilde_expand" on gdbserver, so now the function is using "gdb_tilde_expand" instead. Otherwise, the code is the same. Regression tested on the BuildBot, without regressions. gdb/ChangeLog: 2018-02-28 Sergio Durigan Junior <sergiodj@redhat.com> * Makefile.in (COMMON_SFILES): Add "common/pathstuff.c".

2018-02-09btrace, gdbserver: remove the to_supports_btrace target methodMarkus Metzger1-21/+4
Remove the to_supports_btrace target method and instead rely on detecting errors when trying to enable recording. This will also provide a suitable error message explaining why recording is not possible. For remote debugging, gdbserver will now always advertise branch tracing related packets. When talking to an older GDB, this will cause GDB to try to enable branch tracing and gdbserver to report a suitable error message every time. An older gdbserver will not advertise branch tracing related packets if the one-time check failed, so a newer GDB with this patch will fail to enable branch tracing at remote_enable_btrace() rather than at btrace_enable(). The error message is the same in both cases so there should be no user-visible change. gdb/ * btrace.c (btrace_enable): Remove target_supports_btrace call. * nat/linux-btrace.c (perf_event_pt_event_type): Move.

Change error reporting to use exceptions and be prepared to catch them in gdbserver. We use the exception message in our error reply to GDB.

In handle_extended_wait, the code that handles exec events destroys the existing process_info and creates a new one. It moves the content of syscalls_to_catch from the old to the new vector.

2017-10-14gdbserver: use std::list for all_threadsSimon Marchi1-44/+31
Remove the usage of inferior_list for the all_threads list in gdbserver. The entry field in thread_info is removed, and replaced by a simple ptid field. I added some functions to iterate (for_each_thread) and find threads (find_thread). However, changing all the users of find_inferior & co to use these new functions would have made the patch way too big. So I opted instead to make find_inferior & co some shims, so that the existing code only needs to be updated minimally. We can then update the existing code to use the new functions incrementally (I've started to do the work, but I'll post it afterwards, see [1] if you want a peek). This patch has been built-tested on all relevant platforms, except lynx. I also regtested using the native-gdbserver and native-extended-gdbserver boards on x86.
