* gdb: use libtool in GDB_AC_CHECK_BFDJose E. Marchesi2022-11-151-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GDB_AC_CHECK_BFD macro defined in gdb/acinclude.m4 uses the AC_LINK_IFELSE autoconf macro in order to link a simple program to check features of libbfd. If libbfd's link dependencies change, it was necessary to reflect them either in the definition of the macro, or as a consequence of checking for them with an autoconf macro resulting in an addition to LIBS. This patch modifies the definition of the GDB_CHECK_BFD macro in order to use libtool to perform the test link. This makes it possible to not have to list dependencies of libbfd (which are indirect to GDB) at all. After this patch: configure:28553: checking for ELF support in BFD configure:28573: ./libtool --quiet --mode=link gcc -o conftest \ -I../../gdb/../include -I../bfd \ -I../../gdb/../bfd -g -O2 \ -L../bfd -L../libiberty conftest.c -lbfd -liberty \ -lncursesw -lm -ldl >&5 configure:28573: $? = 0 configure:28583: result: yes Tests performed: - Configure --with-system-zlib and --without-system-zlib. - Check link dependencies of installed GDB with both --enable-shared and --disable-shared. - Run installed GDB in both cases.

* binutils, gdb: support zstd compressed debug sectionsFangrui Song2022-09-261-1/+2

* gdb: don't use -Wmissing-prototypes with g++Andrew Burgess2022-01-131-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit aims to not make use of -Wmissing-prototypes when compiling with g++. Use of -Wmissing-prototypes was added with this commit: commit a0761e34f054767de6d6389929d27e9015fb299b Date: Wed Mar 11 15:15:12 2020 -0400 gdb: enable -Wmissing-prototypes warning Because clang can provide helpful warnings with this flag. Unfortunately, g++ doesn't accept this flag, and will give this warning: cc1plus: warning: command line option ‘-Wmissing-prototypes’ is valid for C/ObjC but not for C++ In theory the fact that this flag is not supported should be detected by the configure check in gdbsupport/warning.m4, but for users of ccache, this check doesn't work due to a long standing ccache issue: https://github.com/ccache/ccache/issues/738 The ccache problem is that -W... options are reordered on the command line, and so -Wmissing-prototypes is seen before -Werror. Usually this doesn't matter, but the above warning (about the flag not being valid) is issued before the -Werror flag is processed, and so is not fatal. There have been two previous attempts to fix this that I'm aware of. The first is: https://sourceware.org/pipermail/gdb-patches/2021-September/182148.html In this attempt, instead of just relying on a compile to check if a flag is valid, the proposal was to both compile and link. As linking doesn't go through ccache, we don't suffer from the argument reordering problem, and the link phase will correctly fail when using -Wmissing-prototypes with g++. The configure script will then disable the use of this flag. This approach was rejected, and the suggestion was to only add the -Wmissing-prototypes flag if we are compiling with gcc. The second attempt, attempts this approach, and can be found here: https://sourceware.org/pipermail/gdb-patches/2021-November/183076.html This attempt only adds the -Wmissing-prototypes flag is the value of GCC is not 'yes'. This feels like it is doing the right thing, unfortunately, the GCC flag is really a 'is gcc like' flag, not a strict, is gcc check. As such, GCC is set to 'yes' for clang, which would mean the flag was not included for clang or gcc. The entire point of the original commit was to add this flag for clang, so clearly the second attempt is not sufficient either. In this new attempt I have added gdbsupport/compiler-type.m4, this file defines AM_GDB_COMPILER_TYPE. This macro sets the variable GDB_COMPILER_TYPE to either 'gcc', 'clang', or 'unknown'. In future the list of values might be extended to cover other compilers, if this is ever useful. I've then modified gdbsupport/warning.m4 to only add the problematic -Wmissing-prototypes flag if GDB_COMPILER_TYPE is not 'gcc'. I've tested this with both gcc and clang and see the expected results, gcc no longer attempts to use the -Wmissing-prototypes flag, while clang continues to use it. When compiling using ccache, I am no longer seeing the warning.
* gdb/gdbserver: switch to AC_CONFIG_MACRO_DIRSMike Frysinger2021-06-191-37/+10
| | | | | | | These dirs don't use automake, so use AC_CONFIG_MACRO_DIRS to specify ../config as a search dir for m4 macros. This allows removal of a lot of hand-written m4_include's from acinclude.m4 files, and simplifies use of `aclocal` or `autoreconf` as manual -I is not needed.

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 configure check for std::threadTom Tromey2019-11-261-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [PR build/24886] disable glibc mcheck supportFrank Ch. Eigler2019-08-061-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

* Update copyright year range in all GDB files.Joel Brobecker2019-01-011-1/+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.
* Add parameter to allow enabling/disabling selftests via configureSergio Durigan Junior2018-10-101-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* gdb: Require C++11Pedro Alves2016-10-281-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use AX_CXX_COMPILE_STDCXX to detect if the compiler supports C++11, and if -std=xxx switches are necessary to enable C++11. We need to tweak AX_CXX_COMPILE_STDCXX a bit though. Pristine upstream AX_CXX_COMPILE_STDCXX appends -std=gnu++11 to CXX directly. That doesn't work for us, because the top level Makefile passes CXX down to subdirs, and that overrides whatever gdb/Makefile may set CXX to. The result would be that a make invocation from the build/gdb/ directory would use "g++ -std=gnu++11" as expected, while a make invocation at the top level would not. So instead of having AX_CXX_COMPILE_STDCXX set CXX directly, tweak it to AC_SUBST a separate variable -- CXX_DIALECT -- and use '$(CXX) (CXX_DIALECT)' to compile/link. Confirmed that this enables C++11 starting with gcc 4.8, the first gcc release with full C++11 support. Also confirmed that configure errors out gracefully with older GCC releases: checking whether /opt/gcc-4.7/bin/g++ supports C++11 features by default... no checking whether /opt/gcc-4.7/bin/g++ supports C++11 features with -std=gnu++11... no checking whether /opt/gcc-4.7/bin/g++ supports C++11 features with -std=gnu++0x... no checking whether /opt/gcc-4.7/bin/g++ supports C++11 features with -std=c++11... no checking whether /opt/gcc-4.7/bin/g++ supports C++11 features with -std=c++0x... no checking whether /opt/gcc-4.7/bin/g++ supports C++11 features with +std=c++11... no checking whether /opt/gcc-4.7/bin/g++ supports C++11 features with -h std=c++11... no configure: error: *** A compiler with support for C++11 language features is required.

The name of the switch should be familiar to those who followed GCC's own C++ conversion process. . Adding -fpermissive to COMPILER in C++ mode (see the new build-with-cxx.m4 file) makes errors like these be warnings instead: gdb/infrun.c:6597:1: error: initializing argument 1 of ‘void sig_print_info(gdb_signal)’ [-fpermissive] sig_print_info (enum gdb_signal oursig) ^ gdb/infrun.c: In function ‘void do_restore_infcall_suspend_state_cleanup(void*)’: gdb/infrun.c:7164:39: error: invalid conversion from ‘void*’ to ‘infcall_suspend_state*’ [-fpermissive] restore_infcall_suspend_state (state); ^ so that the compiler carries on compiling the file. -Werror still catches the warnings, so nothing is lost, only our lifes are made easier by concentrating on getting other more important things out of the way first. There's no way to quiet those warnings. Until they're all fixed, when building in C++ mode, -Werror is disabled by default. . Adding -Wno-narrowing suppresses thousands of instances of this warning: gdb/arm-linux-tdep.c:439:1: error: narrowing conversion of ‘-1’ from ‘int’ to ‘ULONGEST {aka long unsigned int}’ inside { } is ill-formed in C++11 [-Werror=narrowing] gdb/arm-linux-tdep.c:439:1: error: narrowing conversion of ‘-1l’ from ‘LONGEST {aka long int}’ to ‘ULONGEST {aka long unsigned int}’ inside { } is ill-formed in C++11 [-Werror=narrowing] gdb/arm-linux-tdep.c:450:1: error: narrowing conversion of ‘-1’ from ‘int’ to ‘ULONGEST {aka long unsigned int}’ inside { } is ill-formed in C++11 [-Werror=narrowing] We can defer handling those until we target C++11. .

This adds an m4 file that both GDB and GDBserver's configury use to pull in the autoconf checks that libiberty clients needs done in order to use these libiberty.h/ansidecl.h. gdb/ChangeLog: 2015-02-27 Pedro Alves <palves@redhat.com> * libiberty.m4: New file. * acinclude.m4: Include libiberty.m4. * configure.ac: Call libiberty_INIT. * config.in, configure: Regenerate. gdb/gdbserver/ 2015-02-27 Pedro Alves <palves@redhat.com> * acinclude.m4: Include libiberty.m4. * configure.ac: Call libiberty_INIT. * config.in, configure: Regenerate.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces a new M4 macro GDB_AC_TRANSFORM to avoid repeating the common idiom which is the transformation of target program names, i.e. from gdb to sparc64-linux-gnu-gdb.

* introduce common.m4Tom Tromey2013-11-081-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It has bothered me for a while that files in common/ use macros defined via autoconf checks, but rely on each configure.ac doing the proper checks independently. This patch introduces common/common.m4 which consolidates the checks assumed by code in common. The rule I propose is that if something is needed or used by common, it should be checked for by common.m4. However, if the check is also needed by gdb or gdbserver, then it should be duplicated there. Built and regtested on x86-64 Fedora 18 (though this is hardly the most strenuous case) and using the Fedora 18 mingw cross compilers. I also examined the config.in diffs to ensure that symbols did not go missing. 2013-11-08 Tom Tromey <tromey@redhat.com> * acinclude.m4: Include common.m4. * common/common.m4: New file. * configure, config.in: Rebuild. * configure.ac: Use GDB_AC_COMMON. 2013-11-08 Tom Tromey <tromey@redhat.com> * acinclude.m4: Include common.m4, codeset.m4. * configure, config.in: Rebuild. * configure.ac: Use GDB_AC_COMMON.
* On mainline/development, also link GDBserver with -lmcheck.Pedro Alves2013-07-031-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This factors --enable-libmcheck related bits from GDB's configure.ac and makes GDBserver use them too. Specifically, the 'development' global is moved to a separate script to it can be sourced by both GDB and GDBserver, and the --enable-libmcheck/--disable-libmcheck bits proper are moved to a new m4 file. I started out by defining 'development' in the m4 file, but in the end decided against it, as a separate script has the advantage that changing it in release branches does not require regenerating configure, unlike today. I had also started out by making the new GDB_AC_LIBMCHECK itself handle the yes/no default fallback depending on release/developement, but since I had split out 'development' to a separate script, and, GDB needs the python checks anyway (hence we'd need to do the python checks in gdb's configure.ac, and pass in a 'default lmcheck yes/no' parameter to GDB_AC_LIBMCHECK anyway), I ended up keeping GDB_AC_LIBMCHECK isolated from the 'development' global. IOW, it's the caller's business to handle it. Tested on x86_64 Fedora 17. Built GDB and GDBserver with and without --enable-libmcheck, and observed --enable-libmcheck overrides the disablement of -lmcheck caused by python supporting threads, and that GDBserver links with -lmcheck when expected. Also observed that changing the 'development' global, and issuing "make" triggers a relink, and '-lmcheck' is included or not from the link accordingly. gdb/ 2013-07-03 Pedro Alves <palves@redhat.com> * Makefile.in (config.status): Depend on development.sh.
