Create dwarf2/comp-unit.[ch]
This creates the new files dwarf2/comp-unit.[ch], moving comp_unit_head and helpers to those files. A couple of functions are turned into methods, because it was convenient to do so now. 2020-02-08 Tom Tromey <tom@tromey.com> * Makefile.in (COMMON_SFILES): Add dwarf2/comp-unit.c. * dwarf2/read.c (struct comp_unit_head): Move to dwarf2/comp-unit.h. (enum class rcuh_kind): Move to comp-unit.h. (get_cu_length, offset_in_cu_p): Now methods on comp_unit_head. (read_comp_unit_head, error_check_comp_unit_head) (read_and_check_comp_unit_head): Move to comp-unit.c. (read_offset, dwarf_unit_type_name): Likewise.

Move gdbserver to top level
This patch moves gdbserver to the top level. This patch is as close to a pure move as possible -- gdbserver still builds its own variant of gnulib and gdbsupport. Changing this will be done in a separate patch. [v2] Note that, per Simon's review comment, this patch changes the tree so that gdbserver is not built for or1k or score. This makes sense, because there is apparently not actually a gdbserver port here. [v3] This version of the patch also splits out some configury into a new file, gdbserver/configure.host, so that the top-level configure script can simply rely on it in order to decide whether gdbserver should be built. [v4] This version adds documentation and removes some unnecessary top-level dependencies. [v5] Update docs to mention "make all-gdbserver" and change how top-level configure decides whether to build gdbserver, switching to a single, shared script. Tested by the buildbot. ChangeLog 2020-02-07 Tom Tromey <tom@tromey.com> Pedro Alves <palves@redhat.com> * src-release.sh (GDB_SUPPORT_DIRS): Add gdbserver. * gdbserver: New directory, moved from gdb/gdbserver. * configure.ac (host_tools): Add gdbserver.

Move gdbsupport to the top level
This patch moves the gdbsupport directory to the top level. This is the next step in the ongoing project to move gdbserver to the top level. The bulk of this patch was created by "git mv gdb/gdbsupport gdbsupport". This patch then adds a build system to gdbsupport and wires it into the top level. Then it changes gdb to use the top-level build. gdbserver, on the other hand, is not yet changed. It still does its own build of gdbsupport.

Add "info connections" command, "info inferiors" connection number/string
This commit extends the CLI a bit for multi-target, in three ways. #1 - New "info connections" command. This is a new command that lists the open connections (process_stratum targets). For example, if you're debugging two remote connections, a couple local/native processes, and a core dump, all at the same time, you might see something like this: (gdb) info connections Num What Description 1 remote 192.168.0.1:9999 Remote serial target in gdb-specific protocol 2 remote 192.168.0.2:9998 Remote serial target in gdb-specific protocol * 3 native Native process 4 core Local core dump file #2 - New "info inferiors" "Connection" column You'll also see a new matching "Connection" column in "info inferiors", showing you which connection an inferior is bound to: (gdb) info inferiors Num Description Connection Executable 1 process 18526 1 (remote 192.168.0.1:9999) target:/tmp/a.out 2 process 18531 2 (remote 192.168.0.2:9998) target:/tmp/a.out 3 process 19115 3 (native) /tmp/prog1 4 process 6286 4 (core) myprogram * 5 process 19122 3 (native) /bin/hello #3 - Makes "add-inferior" show the inferior's target connection "add-inferior" now shows you the connection you've just bound the inferior to, which is the current process_stratum target: (gdb) add-inferior [New inferior 2] Added inferior 2 on connection 1 (extended-remote localhost:2346) gdb/ChangeLog: 2020-01-10 Pedro Alves <palves@redhat.com> * Makefile.in (COMMON_SFILES): Add target-connection.c. * inferior.c (uiout_field_connection): New function.

Improve process exit status macros on MinGW

Fix install-strip for cross-compilation

Compare iterators, not values, in filtered_iterator::operator{==,!=}
The == and != operators on filtered_iterator are not doing the right thing, they compare values pointed by the wrapped iterators instead of comparing the iterators themselves. As a result, operator== will return true if the two iterators point to two equal values at different positions. operator!= will fail similarly. Also, this causes it to deference past-the-end iterators when doing. For example, in for (iter = ...; iter != end_iter; ++iter) the != comparison dereferences end_iter. I don't think this should happen. I don't think it's a problem today, given that we only use filtered_iterator to wrap linked lists of threads and inferiors. Dereferencing past-the-end iterators of these types is not fatal, it just returns NULL, which is not a value we otherwise find in the lists. But in other contexts, it could become problematic. I have added a simple self test that fails without the fix applied. gdb/ChangeLog: * filtered-iterator.h (filtered_iterator) <operator==, operator!=>: Compare wrapped iterators, not wrapped pointers. * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add unittests/filtered_iterator-selftests.c. * unittests/filtered_iterator-selftests.c: New file. |

Implement a thread pool
This adds a simple thread pool to gdb. In the end, this seemed preferable to the approach taken in an earlier version of this series; namely, starting threads in the parallel-foreach implementation. This approach reduces the overhead of starting new threads, and also lets the user control (in a subsequent patch) exactly how many worker threads are running. gdb/ChangeLog 2019-11-26 Christian Biesinger <cbiesinger@google.com> Tom Tromey <tom@tromey.com> * gdbsupport/thread-pool.h: New file. * gdbsupport/thread-pool.c: New file. * Makefile.in (COMMON_SFILES): Add thread-pool.c.

Add RAII class for blocking gdb signals
This adds configury support and an RAII class that can be used to temporarily block signals that are used by gdb. (This class is not used in this patch, but it split out for easier review.) The idea of this patch is that these signals should only be delivered to the main thread. So, when creating a background thread, they are temporarily blocked; the blocked state is inherited by the new thread. The sigprocmask man page says: The use of sigprocmask() is unspecified in a multithreaded process; see pthread_sigmask(3). This patch changes gdb to use pthread_sigmask when appropriate, by introducing a convenience define. I've updated gdbserver as well, because I had to touch gdbsupport, and because the threading patches will make it link against the thread library.

Add configure check for std::thread
This adds a configure check for std::thread. This is needed because std::thread is not available on some systems, like some versions of mingw and DJGPP. This also adds configury to make sure that a threaded gdb links against the correct threading library (-lpthread or the like), and passes the right flags (e.g., -pthread) to the compilations. Note that this also links gdbserver against the thread library. This is not strictly necessary at this point in the series, but a later patch will change gdbsupport to use pthread_sigmask, at which point this will be needed. gdb/ChangeLog 2019-11-26 Tom Tromey <tom@tromey.com> * acinclude.m4: Include ax_pthread.m4. * Makefile.in (PTHREAD_CFLAGS, PTHREAD_LIBS): New variables.

Use gnulib's strerror_r on MinGW
There is no need to keep mingw-strerror around; we can just always use the code from posix-strerror. The main reason we had that code, it seems, is to handle winsock error codes, but gnulib's version handles those.

gdb_vecs.h: Avoid self move assign
While working on another patch I ran into an issue with unordered_remove (in gdb_vecs.h), where removing the last item of the vector can cause a self move assign. When compiling the C++ standard library in debug mode (with -D_GLIBCXX_DEBUG=1) this causes an error to trigger. I've fixed the issue in this patch and provided a unit test. The provided unit test includes an assignment operator which checks for self move assign, this removes the need to compile with -D_GLIBCXX_DEBUG=1 in order to spot the bug. If you're keen to see the error reported from the C++ standard library then remove operator= from the unit test and recompile GDB with -D_GLIBCXX_DEBUG=1. gdb/ChangeLog: * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add new file to the list. * unittests/vec-utils-selftests.c: New file. * gdbsupport/gdb_vecs.h (unordered_remove): Avoid self move assign.

Move readline to the readline/readline subdirectory
readline turns out to be a bit of a stumbling block for the project to
move gdbsupport (and then gdbserver) to the top-level.
The issue is that readline headers are intended to be included with
names like "readline/readline.h". To support this, gdb effectively
adds a -I option pointing to the top-level source directory -- but,
importantly, this option is not used when the system readline is used.
For gdbsupport, a -I option like this would always be needed, but that
in turn would break the system readline case. This was PR build/17077,
fixed in commit

Fix creation of stamp-h by gdb's configure script
I happened to notice that "make" would always print: CONFIG_HEADERS=config.h:config.in \ CONFIG_COMMANDS="default depdir" \ CONFIG_FILES= \ CONFIG_LINKS= \ /bin/sh config.status config.status: creating config.h config.status: config.h is unchanged on every rebuild. This seems to have changed due to an autoconf upgrade at some point in the past. In the autoconf gdb uses now, it works to use AC_CONFIG_HEADERS and then create the stamp file via the "commands" argument. This patch also fixes up Makefile.in to use the new-style config.status invocation.

Create xml-builtin.h to declare xml_builtins
xml-builtin.c only has character arrays and no dependencies, so this creates a simple header file for that purpose so that gdbserver can include that instead of re-declaring xml_builtin.

gdb: CTF support
This patch adds the CTF (Compact Ansi-C Type Format) support in gdb. Two submissions on which this gdb work depends were posted earlier in May: * On the binutils mailing list - adding libctf which creates, updates, reads, and manipulates the CTF data. * On the gcc mailing list - expanding gcc to directly emit the CFT data with a new command line option -gt. CTF is a reduced form of debugging information whose main purpose is to describe the type of C entities such as structures, unions, typedefs and function arguments at the global scope only. It does not contain debug information about source lines, location expressions, or local variables. For more information on CTF, see the documentation in the libdtrace-ctf source tree, available here: <https://raw.githubusercontent.com/oracle/libdtrace-ctf/master/doc/ctf-format>. This patch expands struct elfinfo by adding the .ctf section, which contains CTF debugging info, and modifies elf_symfile_read() to read it. If both DWARF and CTF exist in a program, only DWARF will be read. CTF data will be read only when there is no DWARF. The two-stage symbolic reading and setting strategy, partial and full, was used. File ctfread.c contains functions to transform CTF data into gdb's internal symbol table structures by iterately reading entries from CTF sections of "data objects", "function info", "variable info", and "data types" when setting up either partial or full symbol table. If the ELF symbol table is available, e.g. not stripped, the CTF reader will associate the found type information with these symbol entries. Due to the proximity between DWARF and CTF (CTF being a much simplified subset of DWARF), some DWARF implementation was reused to support CTF. Test cases ctf-constvars.exp, ctf-cvexpr.exp, ctf-ptype.exp, and ctf-whatis.exp have been added to verify the correctness of this support. This patch has missing features and limitations which we will add and address in the future patches. gdb/ChangeLog +2019-10-07 Weimin Pan <weimin.pan@oracle.com> + + * gdb/ctfread.c: New file. + * gdb/ctfread.h: New file. + * gdb/elfread.c: Include ctfread.h. + (struct elfinfo text_p): New member ctfsect. + (elf_locate_sections): Mark CTF section. + (elf_symfile_read): Call elfctf_build_psymtabs. + * gdb/Makefile.in (LIBCTF): Add. + (CLIBS): Use it. + (CDEPS): Likewise. + (DIST): Add ctfread.c. + * Makefile.def (dependencies): Add all-libctf to all-gdb + * Makefile.in: Add "all-gdb: maybe-all-libctf" + gdb/testsuite/ChangeLog +2019-10-07 Weimin Pan <weimin.pan@oracle.com> + + * gdb.base/ctf-whatis.exp: New file. + * gdb.base/ctf-whatis.c: New file. + * gdb.base/ctf-ptype.exp: New file. + * gdb.base/ctf-ptype.c: New file. + * gdb.base/ctf-constvars.exp: New file. + * gdb.base/ctf-constvars.c: New file. + * gdb.base/ctf-cvexpr.exp: New file. + |

Add a selftest that checks documentation invariants.
Several approaches were discussed (mail or irc) to verify the invariants of the GDB help documentation : checking with apropos ., modifying add_cmd to do the check and output a warning, implement maintenance check-doc. A selftest was finally chosen as: * this can be run on demand, including by users if they want to check user defined commands. * it does not interact with the normal behaviour of apropos, define, python, ... (such as output warnings when a user defines a command help that does not respect the doc). * when the selftest runs, it checks the user defined and python defined commands currently defined. gdb/ChangeLog * unittests/help-doc-selftests.c: New file. * Makefile.in: Add the new file. |

[PR build/24886] disable glibc mcheck support
This patch drops gdb's configury support for glibc's mcheck function. It has been observed to cause false abort()s, because it is thread-unsafe yet interposes every malloc/free operation. So if any library transitively used by gdb also uses threads, then these functions can easily corrupt their own checking data. These days, gcc ASAN and valgrind provide high quality checking, and mcheck is apparently itself being slowly deprecated. So, let's stop linking to it. Attached patch drops the autoconf/Makefile machinery for both gdb and gdbserver. No testsuite-visible impact. IMHO not worth mentioning in NEWS.

Arm: Add read_description read funcs and use in GDB
Switch the Arm target to get target descriptions via arm_read_description and aarch32_read_description, in the same style as other feature targets.

Rearrange TUI data window code
An earlier patch caused tui-windata.h to be essentially empty. And, other earlier patches implemented TUI data window methods in any spot that happened to be convenient at the time. This patch rearranges all the data window code to be somewhat more organized. It moves tui_data_window to tui-regs.h, and moves the implementation of all methods to tui-regs.c. It then removes tui-windata.h and tui-windata.c. It also removes the "structuring" comments from tui-regs.c; these are not the usual gdb style, and were out of date anyhow. Finally, it moves _initialize_tui_regs to the end of the file, per the usual gdb convention. gdb/ChangeLog 2019-07-17 Tom Tromey <tom@tromey.com> * tui/tui.c: Update. * tui/tui-wingeneral.c (tui_data_window::refresh_window): Move to tui-regs.c. * tui/tui-windata.h: Remove file. * tui/tui-windata.c: Remove file. * tui/tui-win.c (tui_data_window::set_new_height) (tui_data_window::do_make_visible_with_new_height): Move to tui-regs.c. * tui/tui-regs.h (struct tui_data_window): Move from tui-data.h. * tui/tui-regs.c: Remove "structuring" comments.

Rename common to gdbsupport
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. *

Move gnulib to top level
This patch moves the gdb/gnulib subdirectory to the top level. It adjusts the top-level build system to build gnulib when necessary, and changes gdb to use this. However, gdbserver still builds its own copy of gnulib, just from the new source location. A small hack was needed to ensure that gnulib is only built when gdb is enabled. The Makefile only provides an ordering -- the directory must be mentioned in configdirs to actually be compiled at all. Most of the patch is just a "git mv" of gnulib, though a few minor path adjustments were needed in some files there. Tested by the buildbot.

Introduce generic command options framework
This commit adds a generic command options framework, that makes it easy enough to add '-'-style options to commands in a uniform way, instead of each command implementing option parsing in its own way. Options are defined in arrays of option_def objects (for option definition), and the same options definitions are used for supporting TAB completion, and also for generating the relevant help fragment of the "help" command. See the gdb::options::build_help function, which returns a string with the result of replacing %OPTIONS% in a template string with an auto-generated "help" string fragment for all the passed-in options. Since most options in GDB are in the form of "-OPT", with a single dash, this is the format that the framework supports. I like to think of gdb's "-OPT" as the equivalent to getopt's long options format ("--OPT"), and gdb's "/" as the equivalent to getopt's short options format. getopt's short options format allows mixing several one-character options, like "ls -als", kind of similar to gdb's "x /FMT" and "disassemble /MOD", etc. While with gdb's "-" options, the option is expected to have a full name, and to be abbreviatable. E.g., "watch -location", "break -function main", etc. This patch only deals with "-" options. The above comment serves more to disclose why I don't think we should support mixing several unrelated options in a single "-" option invocation, like "thread apply -qcs" instead of "thread apply -q -c -s". The following patches will add uses of the infrastructure to several key commands. Most notably, "print", "compile print", "backtrace", "frame apply" and "thread apply". I tried to add options to several commands in order to make sure the framework didn't leave that many open holes open. Options use the same type as set commands -- enum var_types. So boolean options are var_boolean, enum options are var_enum, etc. The idea is to share code between settings commands and command options. The "print" options will be based on the "set print" commands, and their names will be the same. Actually, their definitions will be the same too. There is a function to create "set/show" commands from an array for option definitions: /* Install set/show commands for options defined in OPTIONS. DATA is a pointer to the structure that holds the data associated with the OPTIONS array. */ extern void add_setshow_cmds_for_options (command_class cmd_class, void *data, gdb::array_view<const option_def> options, struct cmd_list_element **set_list, struct cmd_list_element **show_list); That will be used by several following patches. Other features: - You can use the "--" delimiter to explicitly indicate end of options. Several existing commands use this token sequence for this effect already, so this just standardizes it. - You can shorten option names, as long as unambiguous. Currently, some commands allow this (e.g., break -function), while others do not (thread apply all -ascending). As GDB allows abbreviating command names and other things, it feels more GDB-ish to allow abbreviating option names too, to me. - For boolean options, 0/1 stands for off/on, just like with boolean "set" commands. - For boolean options, "true" is implied, just like with boolean "set commands. These are the option types supported, with a few examples: - boolean options (var_boolean). The option's argument is optional. (gdb) print -pretty on -- *obj (gdb) print -pretty off -- *obj (gdb) print -p -- *obj (gdb) print -p 0 -- *obj - flag options (like var_boolean, but no option argument (on/off)) (gdb) thread apply all -s COMMAND - enum options (var_enum) (gdb) bt -entry-values compact (gdb) bt -e c - uinteger options (var_uinteger) (gdb) print -elements 100 -- *obj (gdb) print -e 100 -- *obj (gdb) print -elements unlimited -- *obj (gdb) print -e u -- *obj - zuinteger-unlimited options (var_zuinteger_unlimited) (gdb) print -max-depth 100 -- obj (gdb) print -max-depth -1 -- obj (gdb) print -max-depth unlimited -- obj Other var_types could be supported, of course. These were just the types that I needed for the commands that I ported over, in the following patches. It was interesting (and unfortunate) to find that we need at least 3 different modes to cover the existing commands: - Commands that require ending options with "--" if you specify any option: "print" and "compile print". - Commands that do not want to require "--", and want to error out if you specify an unknown option (i.e., an unknown argument that starts with '-'): "compile code" / "compile file". - Commands that do not want to require "--", and want to process unknown options themselves: "bt", because of "bt -COUNT", "thread/frame apply", because "-" is a valid command. The different behavior is encoded in the process_options_mode enum, passed to process_options/complete_options. For testing, this patch adds one representative maintenance command for each of the process_options_mode values, that are used by the testsuite to exercise the options framework: (gdb) maint test-options require-delimiter (gdb) maint test-options unknown-is-error (gdb) maint test-options unknown-is-operand and adds another command to help with TAB-completion testing: (gdb) maint show test-options-completion-result See their description at the top of the maint-test-options.c file.

New set/show testing framework (gdb.base/settings.exp)
This commit adds new representative commands for all types of settings commands supported by gdb (enum var_types), and then uses them to exercise settings parsing and completion. (gdb) maint test-settings s[TAB] set show (gdb) maint test-settings set [TAB] auto-boolean integer uinteger boolean optional-filename zinteger enum string zuinteger filename string-noescape zuinteger-unlimited (gdb) maint test-settings set enum [TAB] xxx yyy zzz etc. This is basically unit testing, except that it goes fully via GDB. It must be done this way in order to exercise TAB completion properly, which must go via readline. gdb/ChangeLog: 2019-06-13 Pedro Alves <palves@redhat.com> * Makefile.in (COMMON_SFILES): Add maint-test-settings.c. * NEWS: Mention maint test-settings KIND. * maint-test-settings.c: New file. gdb/doc/ChangeLog: 2019-06-13 Pedro Alves <palves@redhat.com> * gdb.texinfo (Maintenance Commands): Document "maint test-settings" commands. gdb/testsuite/ChangeLog: 2019-06-13 Pedro Alves <palves@redhat.com> * gdb.base/settings.c: New file. * gdb.base/settings.exp: New file. |

Move gdb's xmalloc and friends to new file
When "common" becomes a library, linking will cause a symbol clash, because "xmalloc" and some related symbols are defined in that library, libiberty, and readline. To work around this problem, this patch moves the clashing symbols to a new file, which is then compiled separately for both gdb and gdbserver. gdb/ChangeLog 2019-06-11 Tom Tromey <tom@tromey.com> * common/common-utils.c (xmalloc, xrealloc, xcalloc) (xmalloc_failed): Move to alloc.c. * alloc.c: New file. * Makefile.in (COMMON_SFILES): Add alloc.c. gdb/gdbserver/ChangeLog 2019-06-11 Tom Tromey <tom@tromey.com> * Makefile.in (SFILES): Add alloc.c. (OBS): Add alloc.o. (IPA_OBJS): Add alloc-ipa.o. (alloc-ipa.o): New target. (%.o: ../%.c): New pattern rule. |

Move type stack handling to a new class
This introduces a new "type_stack" class, and moves all the parser type stack handling to this class. Parsers that wish to use this facility must now instantiate this class somehow. I chose this approach because a minority of the existing parsers require this. gdb/ChangeLog 2019-04-04 Tom Tromey <tom@tromey.com> * type-stack.h: New file. * type-stack.c: New file. * parser-defs.h (enum type_pieces, union type_stack_elt): Move to type-stack.h. (insert_into_type_stack, insert_type, push_type, push_type_int) (insert_type_address_space, pop_type, pop_type_int) (pop_typelist, pop_type_stack, append_type_stack) (push_type_stack, get_type_stack, push_typelist) (follow_type_instance_flags, follow_types): Don't declare. * parse.c (type_stack): Remove global.

Add a new function child_path.
child_path returns a pointer to the first component in a child path that comes after a parent path. This does not depend on trying to stat() the paths since they may describe remote paths but instead relies on filename parsing. The function requires that the child path describe a filename that contains at least one component below the parent path and returns a pointer to the first component. gdb/ChangeLog: * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add unittests/child-path-selftests.c. * common/pathstuff.c (child_path): New function. * common/pathstuff.h (child_path): New prototype. * unittests/child-path-selftests.c: New file. |
