* Move gdbserver to top levelTom Tromey2020-02-071-719/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Add install-strip target to gdbserverHannes Domani2020-01-241-0/+10
| | | | | | | | | | | | | So far this was only possible indirectly when invoked from the gdb directory. This makes the install-strip target independent from gdb. 2020-01-24 Hannes Domani <ssbssa@yahoo.de> * Makefile.in (install-strip): New target. (install_sh, INSTALL_STRIP_PROGRAM, STRIP): New variables. * aclocal.m4: Regenerate. * configure: Regenerate. * configure.ac: Add AM_PROG_INSTALL_STRIP.

| | | | | | | | | | Complement commit 7ea814144a31 ("Fully disentangle gdb and gdbserver"), <https://sourceware.org/ml/gdb-patches/2002-02/msg00692.html> (from 2002!), and remove a recipe to include config files in `make TAGS', which are no longer used by `gdbserver' as from that commit. gdb/gdbserver/ * Makefile.in (TAGS): Remove config files from the recipe.
* Move gdbsupport to the top levelTom Tromey2020-01-141-31/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* gdbserver: remove rule for files from regformats/i386Simon Marchi2020-01-131-3/+0
| | | | | | | | | | The dat files in regformats/i386 were removed a while ago, this rule is no longer necessary. gdb/gdbserver/ChangeLog: * Makefile.in (%-generated.c): Remove rule for files from regformats/i386.
* gdbserver: fix Makefile dependency of regformat-generated files on regdat.shSimon Marchi2020-01-131-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | The intent of the rules modified by this patch is that the *-generated.c files generated by regdat.sh are re-generated in the event that regdat.sh is modified. However, if I build, touch regdat.sh, and build again, the files are not re-generated during the second build. This is because regdat.sh is specified as an order-only dependency [1], after the pipe. Make therefore only ensures that regdat.sh exists before generating the target file, it doesn't check the timestamp of regdat.sh. This patch changes it to be a regular prerequisite. The rules use the $< variable, which is substituted by the first prerequisite only, so the command lines won't change.

* Improve process exit status macros on MinGWEli Zaretskii2020-01-061-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a Windows program is terminated by a fatal exception, its exit code is the value of that exception, as defined by the various EXCEPTION_* symbols in the Windows API headers. This commit emulates WTERMSIG etc. by translating the fatal exception codes to more-or-less equivalent Posix signals. gdb/ChangeLog: 2020-01-06 Eli Zaretskii <eliz@gnu.org> Pedro Alves <palves@redhat.com> * Makefile.in (COMMON_SFILES): Add gdbsupport/gdb_wait.c. * windows-tdep.c: New enumeration of WINDOWS_SIG* signals.

* Fix install-strip for cross-compilationHannes Domani2020-01-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The variable INSTALL_PROGRAM_ENV sets up STRIPPROG for the cross-compiler. If this is not done, the host 'strip' is used, and fails: /bin/sh /c/src/repos/binutils-gdb.git/install-sh -c -s gdb.exe \ /gdb/gdb64-git/bin/$transformed_name.exe strip.exe:C:/gdb/gdb64-git/bin/_inst.33599_: file format not recognized With this change, it's fine: STRIPPROG='x86_64-w64-mingw32-strip' \ /bin/sh /c/src/repos/binutils-gdb.git/install-sh -c -s gdb.exe \ /gdb/gdb64-git/bin/$transformed_name.exe gdb/ChangeLog: 2020-01-01 Hannes Domani <ssbssa@yahoo.de> * Makefile.in: Use INSTALL_PROGRAM_ENV. gdb/gdbserver/ChangeLog: 2020-01-01 Hannes Domani <ssbssa@yahoo.de> * Makefile.in: Use INSTALL_PROGRAM_ENV.
* Update copyright year range in all GDB files.Joel Brobecker2020-01-011-1/+1
| | | | | | gdb/ChangeLog: Update copyright year range in all GDB files.
* Fix build with GNU Make 3.81Bernd Edlinger2019-12-191-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GNU Make 3.81 is apparently confused when the same source file is processed by a pattern rule and an explicit rule at the same time with different output file. The pattern %.o: ../%.c and alloc-ipa.o: ../alloc.c both have the source ../alloc.c but two independent object files alloc.o and alloc-ipa.o, so while building gdbserver I see the following message: make[4]: Circular alloc-ipa.o <- ../alloc.c dependency dropped. CXX alloc-ipa.o g++: warning: '-x c++' after last input file has no effect g++: fatal error: no input files compilation terminated. In the make debug output I see the pattern is first correct: alloc-ipa.o: ../alloc.c | config.h build-gnulib-gdbserver/import/string.h $(IPAGENT_COMPILE) $(WARN_CFLAGS_NO_FORMAT) $< $(POSTCOMPILE) But after the "Circular" dependency is dropped, the pattern is changed to: alloc-ipa.o: | config.h build-gnulib-gdbserver/import/string.h $(IPAGENT_COMPILE) $(WARN_CFLAGS_NO_FORMAT) $< $(POSTCOMPILE) So indeed now $< is empty, and the build step fails. This happens only when alloc.o needs to be built, when alloc.o was already built, the build succeeds, but it takes often several attempts until the build succeeds. By rewriting the alloc-ipa.c: ../alloc.c rule into a pattern rule, the problem goes away. While already at it, this patch removes also the $(WARN_CFLAGS_NO_FORMAT) from the build rule, which is just a copy/paste thing that is not necessary for alloc.c at all.
* Replace the remaining uses of strerror with safe_strerrorChristian Biesinger2019-12-101-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To do that, this patch makes IPA compile safe-strerror as well. Because it doesn't use Gnulib, it calls the Glibc version of strerror_r directly. Consequently this patch also removes the configure checks for strerror. gdb/ChangeLog: 2019-12-10 Christian Biesinger <cbiesinger@google.com> * config.in: Regenerate. * configure: Regenerate. * gdbsupport/agent.c (gdb_connect_sync_socket): Call safe_strerror instead of strerror. * gdbsupport/common.m4: Don't check for strerror. * gdbsupport/safe-strerror.c: Support both the glibc version of strerror_r and the XSI version. gdb/gdbserver/ChangeLog: 2019-12-10 Christian Biesinger <cbiesinger@google.com> * Makefile.in: Add safe-strerror.c to gdbreplay and IPA, and change UNDO_GNULIB_CFLAGS to undo strerror_r instead of strerror. * config.in: Regenerate. * configure: Regenerate. * configure.ac: Don't check for strerror. * linux-i386-ipa.c (initialize_fast_tracepoint_trampoline_buffer): Call safe_strerror instead of strerror. * server.h (strerror): Remove this now-unnecessary declaration. * tracepoint.c (init_named_socket): Call safe_strerror instead of strerror.

* Add configure check for std::threadTom Tromey2019-11-261-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 MinGWChristian Biesinger2019-11-151-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Unfortunately the code can't be moved into common-utils.c because libinproctrace.so uses common-utils but not gnulib. gdb/ChangeLog: 2019-11-15 Christian Biesinger <cbiesinger@google.com> * Makefile.in: Replace {posix,mingw}-strerror.c with safe-strerror.c. * configure: Regenerate. * configure.ac: Don't source common.host. * gdbsupport/common.host: Remove. * gdbsupport/mingw-strerror.c: Remove. * gdbsupport/posix-strerror.c: Rename to... * gdbsupport/safe-strerror.c: ...this. gdb/gdbserver/ChangeLog: 2019-11-15 Christian Biesinger <cbiesinger@google.com> * Makefile.in: Add safe-strerror.c. * configure: Regenerate. * configure.ac: Don't source common.host.

* Fix creation of stamp-h by gdb's configure scriptTom Tromey2019-10-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. It's no longer necessary to pass the output file names via environment variables. gdb/ChangeLog 2019-10-17 Tom Tromey <tromey@adacore.com> * configure: Rebuild. * configure.ac: Use AC_CONFIG_HEADERS.

* Fix type of startup_with_shell in gdbserverTom Tromey2019-10-021-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | startup_with_shell was changed to be of "bool" type, but I noticed that the definition in gdbserver disagreed. This disagreement caused some regressions on a big-endian machine. This patch removes the redundant declaration and definition of startup_with_shell and ensures that such clashes will be diagnosed.

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.

* Move gnulib to top levelTom Tromey2019-06-141-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Move gdb's xmalloc and friends to new fileTom Tromey2019-06-111-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [PR gdb/23985] Fix libinproctrace.so buildSzabolcs Nagy2019-01-301-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The IPA objects currently may use gnulib replacement apis, which is wrong: gnulib is not linked into the produced dso and it cannot be because it is not built with -fPIC -fvisibility=hidden. The gnulib replacement detection is broken under cross compilation: for targets other than *-gnu*, replacements are enabled that depend on execution time detection. This causes unnecessary build failure when the target has proper support for the replaced api. This fix tries to undo the replacements, which is tricky because the gnulib headers are still used for various compile time fixups and there is no simple knob in gnulib to only turn the replacements off. Without this workaround gdb fails to cross build to non-gnu targets: ld: tracepoint-ipa.o: in function `gdb_agent_helper_thread(void*)': gdb/gdbserver/tracepoint.c:7221: undefined reference to `rpl_strerror' ...

* Implement IPv6 support for GDB/gdbserverSergio Durigan Junior2018-07-111-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements IPv6 support for both GDB and gdbserver. Based on my research, it is the fourth attempt to do that since 2006. Since I used ideas from all of the previous patches, I also added their authors's names on the ChangeLogs as a way to recognize their efforts. For reference sake, you can find the previous attempts at: https://sourceware.org/ml/gdb-patches/2006-09/msg00192.html https://sourceware.org/ml/gdb-patches/2014-02/msg00248.html https://sourceware.org/ml/gdb-patches/2016-02/msg00226.html The basic idea behind the patch is to start using the new 'getaddrinfo'/'getnameinfo' calls, which are responsible for translating names and addresses in a protocol-independent way. This means that if we ever have a new version of the IP protocol, we won't need to change the code again (or, at least, won't have to change the majority of the code). The function 'getaddrinfo' returns a linked list of possible addresses to connect to. Dealing with multiple addresses proved to be a hard task with the current TCP auto-retry mechanism implemented on ser-tcp:net_open. For example, when gdbserver listened only on an IPv4 socket: $ ./gdbserver --once 127.0.0.1:1234 ./a.out and GDB was instructed to try to connect to both IPv6 and IPv4 sockets: $ ./gdb -ex 'target extended-remote localhost:1234' ./a.out the user would notice a somewhat big delay before GDB was able to connect to the IPv4 socket. This happened because GDB was trying to connect to the IPv6 socket first, and had to wait until the connection timed out before it tried to connect to the IPv4 socket. For that reason, I had to rewrite the main loop and implement a new method for handling multiple connections. After some discussion, Pedro and I agreed on the following algorithm: 1) For each entry returned by 'getaddrinfo', we try to open a socket and connect to it. 2.a) If we have a successful 'connect', we just use that connection. 2.b) If we don't have a successfull 'connect', but if we've got a ECONNREFUSED (meaning the the connection was refused), we keep track of this fact by using a flag. 2.c) If we don't have a successfull 'connect', but if we've got a EINPROGRESS (meaning that the connection is in progress), we perform a 'select' call on the socket until we have a result (either a successful connection, or an error on the socket). 3) If tcp_auto_retry is true, and we haven't gotten a successful connection, and at least one of our attempts failed with ECONNREFUSED, then we wait a little bit (i.e., call 'wait_for_connect'), check to see if there was a timeout/interruption (in which case we bail out), and then go back to (1). After multiple tests, I was able to connect without delay on the scenario described above, and was also able to connect in all other types of scenarios. I also implemented some hostname parsing functions (along with their corresponding unit tests) which are used to help GDB and gdbserver to parse hostname strings provided by the user. These new functions are living inside common/netstuff.[ch]. I've had to do that since IPv6 introduces a new URL scheme, which defines that square brackets can be used to enclose the host part and differentiate it from the port (e.g., "[::1]:1234" means "host ::1, port 1234"). I spent some time thinking about a reasonable way to interpret what the user wants, and I came up with the following: - If the user has provided a prefix that doesn't specify the protocol version (i.e., "tcp:" or "udp:"), or if the user has not provided any prefix, don't make any assumptions (i.e., assume AF_UNSPEC when dealing with 'getaddrinfo') *unless* the host starts with "[" (in which case, assume it's an IPv6 host). - If the user has provided a prefix that does specify the protocol version (i.e., "tcp4:", "tcp6:", "udp4:" or "udp6:"), then respect that. This method doesn't follow strictly what RFC 2732 proposes (that literal IPv6 addresses should be provided enclosed in "[" and "]") because IPv6 addresses still can be provided without square brackets in our case, but since we have prefixes to specify protocol versions I think this is not an issue. Another thing worth mentioning is the new 'GDB_TEST_SOCKETHOST' testcase parameter, which makes it possible to specify the hostname (without the port) to be used when testing GDB and gdbserver. For example, to run IPv6 tests: $ make check-gdb RUNTESTFLAGS='GDB_TEST_SOCKETHOST=tcp6:[::1]' Or, to run IPv4 tests: $ make check-gdb RUNTESTFLAGS='GDB_TEST_SOCKETHOST=tcp4:127.0.0.1' This required a few changes on the gdbserver-base.exp, and also a minimal adjustment on gdb.server/run-without-local-binary.exp. Finally, I've implemented a new testcase, gdb.server/server-connect.exp, which is supposed to run on the native host and perform various "smoke tests" using different connection methods. This patch has been regression-tested on BuildBot and locally, and also built using a x86_64-w64-mingw32 GCC, and no problems were found. gdb/ChangeLog: 2018-07-11 Sergio Durigan Junior <sergiodj@redhat.com> Jan Kratochvil <jan.kratochvil@redhat.com> Paul Fertser <fercerpav@gmail.com> Tsutomu Seki <sekiriki@gmail.com> Pedro Alves <palves@redhat.com> * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add 'unittests/parse-connection-spec-selftests.c'.

* Make gdbreplay use more common routinesPedro Alves2018-06-081-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix dependency tracking in gdbserver subdirectoriesSimon Marchi2018-04-191-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dependency tracking (the thing that knows which source file included which other source file during last build to know what to rebuild when an included file changes) is broken for gdbserver subdirectories (arch and common). The dependency tracking files are created in the form arch/.deps/i386.Po but we try to include .deps/arch/i386.Po An easy smoke test is too "touch" the gdb/features/i386/32bit-core.c file in the source directory and try to rebuild gdbserver. This file is included by gdb/arch/i386.c, so it should cause gdb/gdbserver/arch/i386.o in the build directory to be rebuilt. It currently isn't rebuilt, but is with this patch applied. This patch copies the technique used in GDB to transform the dep file paths to the proper form. Also, while testing using the depcomp method of dependency tracking (by just hacking the condition), I noticed that depcomp was not found. The path to depcomp seems to be missing a "..". gdb/gdbserver/ChangeLog: * Makefile.in (depcomp): Add "..". (all_deps_files): New and use it.

* Add silent Makefile rulesSimon Marchi2018-03-161-27/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many projects (e.g. the Linux kernel) and build systems use "silent" rules, which means that they'll only print a summary of what's being done instead of printing all the detailed command lines. While chatting on the #gdb IRC channel, I realized a few people (including me) thought it would be nice to have it in GDB too. The idea is that too much text is not useful, the important information gets lost. If there's only the essential information, it's more likely to be useful. Most of the time, when I look at the build output, it's to see how it's progressing. By just printing a brief summary of each operation, I can easily spot what's currently being compiled and therefore how the build progresses (with time you know the order in which files are compiled almost by heart). As with other projects (Linux, automake-based things, probably others), it's possible to print the complete command lines by passing V=1 to make (or any other non-zero value). I had one hesitation about this: when people report build failures, we are more likely to miss the full compile command line. We'll probably sometimes need to ask people to include the build log with "make V=1". I don't think it's a big downside, if other projects the size of the Linux kernel can live with it, I'm sure we can too. gdb/ChangeLog: * silent-rules.mk: New. * Makefile.in: Include silent-rules.mk (srcdir, VPATH, top_srcdir): Move up.

* Create new common/pathstuff.[ch]Sergio Durigan Junior2018-02-281-0/+2

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.

* Introduce gdb_tilde_expandSergio Durigan Junior2017-10-041-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, whenever we want to handle paths provided by the user and perform tilde expansion on GDB, we rely on "tilde_expand", which comes from readline. This was enough for our use cases so far, but the situation will change when we start dealing with paths on gdbserver as well, which is what the next patches implement. Unfortunately it is not possible to use "tilde_expand" in this case because gdbserver doesn't use readline. For that reason I decided to implement a new "gdb_tilde_expand" function, which is basically a wrapper for "glob" and its GNU extension, GLOB_TILDE_CHECK. With the import of the "glob" module from gnulib, we're sure that "glob" always supports this extension. gdb/ChangeLog: 2017-10-04 Sergio Durigan Junior <sergiodj@redhat.com> * Makefile.in (SFILES): Add gdb_tilde_expand.c.
