2019-10-17Fix creation of stamp-h by gdb's configure scriptTom Tromey1-2/+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. Create stamp-h there, not in AC_CONFIG_FILES invocation. * Makefile.in (Makefile, data-directory/Makefile, stamp-h): Use new-style config.status invocation. gdb/gdbserver/ChangeLog 2019-10-17 Tom Tromey <tromey@adacore.com> * configure: Rebuild. * configure.ac: Use AC_CONFIG_HEADERS.

2019-10-15gdb/gdbserver: Remove reference to vec-ipa.oAndrew Burgess1-1/+0
This comit: commit 0dc327459b19e6765c8fe80957f5c8620611628e Date: Mon Oct 7 16:38:53 2019 +0100 gdb: Remove vec.{c,h} and update code to not include vec.h Broke the GDB build due to leaving a reference to vec-ipa.o in the Makefile.in, this file is built from vec.c which has been removed. I got away with this as I had an old version of the vec-ipa.o file still in my build tree. With this commit in place a clean build now completed successfully. gdb/ChangeLog: * Makefile.in: Remove references to vec-ipa.o. Change-Id: I4cf55951158dd7ee8f60cd054311a7c367e1d7bf

Removes vec.c and vec.h from the source tree, and remove all the remaining includes of vec.h. There should be no user visible changes after this commit.

2019-10-02Fix type of startup_with_shell in gdbserverTom Tromey1-0/+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 moves the declaration to common-inferior.h, and introduces a new common-inferior.c, as suggested by Pedro. gdb/ChangeLog 2019-10-02 Tom Tromey <tromey@adacore.com> * Makefile.in (COMMON_SFILES): Add common-inferior.c. * gdbsupport/common-inferior.c: New file. * infcmd.c (startup_with_shell): Don't define. * nat/fork-inferior.h (startup_with_shell): Don't declare. * gdbsupport/common-inferior.h (startup_with_shell): Declare. * inferior.h (startup_with_shell): Don't declare. gdb/gdbserver/ChangeLog 2019-10-02 Tom Tromey <tromey@adacore.com> * Makefile.in (SFILES): Add common-inferior.c.

2019-07-09Rename common to gdbsupportTom Tromey1-68/+68
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.

2019-06-14Move gnulib to top levelTom Tromey1-2/+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. ChangeLog 2019-06-14 Tom Tromey <tom@tromey.com> * MAINTAINERS: Add gnulib. * gnulib: New directory, move from gdb/gnulib. * configure.ac (host_libs): Add gnulib. * configure: Rebuild. * Makefile.def (host_modules, dependencies): Add gnulib. * Makefile.in: Rebuild. gdb/ChangeLog 2019-06-14 Tom Tromey <tom@tromey.com> * gnulib: Move directory to top-level. * configure.ac: Don't configure gnulib. * configure: Rebuild. * common/common-defs.h: Use new path to gnulib. * Makefile.in (GNULIB_BUILDDIR): Now ../gnulib.

2019-06-11Move gdb's xmalloc and friends to new fileTom Tromey1-0/+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. 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.

2019-01-30[PR gdb/23985] Fix libinproctrace.so buildSzabolcs Nagy1-0/+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' ...

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.

2018-07-11Implement IPv6 support for GDB/gdbserverSergio Durigan Junior1-0/+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'.

2018-06-08Make gdbreplay use more common routinesPedro Alves1-1/+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.

Share target description declarations and selection among ppc linux native targets, core files, gdbserver and IPA. To avoid complicated define guards, gdbserver and IPA now have declarations for all descriptions, including 64-bit generated descriptions when compiled in 32-bit mode. These have always been linked into the gdbserver and IPA binaries.

2018-04-19Fix dependency tracking in gdbserver subdirectoriesSimon Marchi1-2/+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.

2018-03-16Add silent Makefile rulesSimon Marchi1-27/+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.

2018-02-28Create new common/pathstuff.[ch]Sergio Durigan Junior1-0/+2
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.

2017-10-04Introduce gdb_tilde_expandSergio Durigan Junior1-0/+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.

2017-09-05Share i386-linux target description between GDB and GDBserverYao Qi1-0/+8
The code on creating i386-linux target descriptions are quite similar between GDB and GDBserver, so this patch moves them into a shared file arch/i386.c.

2017-09-05Use VEC for target_desc.reg_defsYao Qi1-0/+1
Nowadays, target_desc.reg_defs is a pointer points to a pre-generated array, which is not flexible. This patch changes it from an array to a VEC so that GDBserver can create target descriptions dynamically later. Instead of using pre-generated array, the -generated.c calls VEC_safe_push to add each register to vector. Since target_desc.reg_defs is used in IPA, we need to build common/vec.c for IPA too. gdb/gdbserver: 2017-09-05 Yao Qi <yao.qi@linaro.org> * Makefile.in (IPA_OBJS): Add vec-ipa.o * regcache.c (get_thread_regcache): Use VEC_length.

2017-09-04gdbserver Makefile: don't delete intermediary filesSimon Marchi1-0/+3
If you "make" from scratch in gdbserver/, you'll notice that make deletes the files it considers as intermediary at the end: $ make clean && make ... rm i386-mmx-linux-generated.c x32-avx-avx512-linux-generated.c ... Then, if you type make again, make will rebuild these files and rebuild gdbserver. To avoid this, we can add the .SECONDARY special target. If it has no pre-requisites, all intermediary files will be kept. gdb/gdbserver/ChangeLog: * Makefile.in (.SECONDARY): Define target.

Because we are compiling .c files containing C++ code, clang++ complains with: clang: error: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated If renaming all the source files to .cpp is out of the question, an alternative is to pass "-x c++" to convince the compiler that we are really compiling C++.

2017-06-07Share fork_inferior et al with gdbserverSergio Durigan Junior1-0/+1
This is the most important (and the biggest, sorry) patch of the series. It moves fork_inferior from gdb/fork-child.c to nat/fork-inferior.c and makes all the necessary adjustments to both GDB and gdbserver to make sure everything works OK. There is no "most important change" with this patch; all changes are made in a progressive way, making sure that gdbserver had the necessary features while not breaking GDB at the same time. I decided to go ahead and implement a partial support for starting the inferior with a shell on gdbserver, although the full feature comes in the next patch. The user won't have the option to disable the startup-with-shell, and also won't be able to change which shell gdbserver will use (other than setting the $SHELL environment variable, that is). Everything is working as expected, and no regressions were present during the tests. gdb/ChangeLog: 2017-06-07 Sergio Durigan Junior <sergiodj@redhat.com> Pedro Alves <palves@redhat.com> * Makefile.in (HFILES_NO_SRCDIR): Add "common/common-inferior.h" and "nat/fork-inferior.h". * common/common-inferior.h: New file, with contents from "gdb/inferior.h". * commom/common-utils.c: Include "common-utils.h".

2017-06-07Move parts of inferior job control to common/Sergio Durigan Junior1-0/+2
This commit moves a few bits responsible for dealing with inferior job control from GDB to common/, which makes them available to gdbserver. This is necessary for the upcoming patches that will share fork_inferior et al between GDB and gdbserver. We move some parts of gdb/terminal.h to gdb/common/common-terminal.h, especifically the code that checks terminal features and that are used to set job_control accordingly. After sharing parts of gdb/terminal.h, we also to share the two functions on gdb/inflow.c that are going to be needed by the fork_inferior rework. They are 'gdb_setpgid' and the new 'have_job_control'. I've also taken the opportunity to give a more meaningful name to "inflow.c" on common/. Now it is called "job-control.c" (thanks Pedro for the suggestion). gdb/ChangeLog: 2017-06-07 Sergio Durigan Junior <sergiodj@redhat.com> * Makefile.in (SFILES): Add "common/job-control.c".

2017-04-04gdbserver: Clear .deps on cleanSimon Marchi1-0/+1
In some situations, the dependency tracking files in .deps can refer to source files that were removed or renamed, leading to errors like: make: *** No rule to make target `version.c', needed by `version.o'. Stop. This patch makes the clean target clear the .deps directory, which gives the user a chance to recover from the error wihtout knowing about the internals of the build system. It is already done for GDB. See here for more details: https://sourceware.org/ml/gdb-patches/2009-03/msg00000.html gdb/gdbserver/ChangeLog: * Makefile.in (clean): Clear .deps.
2017-03-31gdbserver: Suffix generated C files with -generatedSimon Marchi1-48/+20
I noticed that there were some missing files in gdbserver's gitignore (some generated register format .c files). Of course the easy fix would be to add those files to .gitignore, but I think we can do a better job, so that we don't have to worry about adding generated files to .gitignore or the clean Makefile target. I suggest naming all generated source files -generated.c. This way, we can use a single rule in .gitignore and do a "rm -f *-generated.c" to clean them up. New in v2: - Don't rename version.o and xml-builtin.o gdb/gdbserver/ChangeLog: * .gitignore: Remove generated files, replace with wildcard. * (clean): Replace removal of generated files with wildcard.

2017-03-07Share gdb/environ.[ch] with gdbserverSergio Durigan Junior1-0/+5
We will need access to the environment functions when we share fork_inferior between GDB and gdbserver, therefore we simply make the API on gdb/environ.[ch] available on common/. No extra adjustments are needed to make it compile on gdbserver. gdb/ChangeLog: 2017-03-07 Sergio Durigan Junior <sergiodj@redhat.com> * Makefile.in (SFILES): Replace "environ.c" with "common/environ.c". (HFILES_NO_SRCDIR): Likewise, for "environ.h". * environ.c: Include "common-defs.h" instead of "defs.h. Moved to... * common/environ.c: ... here. * environ.h: Moved to... * common/environ.h: ... here. gdb/gdbserver/ChangeLog: 2017-03-07 Sergio Durigan Junior <sergiodj@redhat.com> * Makefile.in (SFILES): Add "common/environ.c". (OBJS): Add "common/environ.h".
