gdbserver/gdbsupport: Add .dir-locals.el file Copy the .dir-locls.el file from gdb/ to gdbserver/ and gdbsupport/ so that we get the GNU/GDB style when editing these files in Emacs. I initially wanted to remove the (c-mode . ((mode . c++))) that switches c-mode files into c++-mode as we store C++ code in *.cc files in the gdbserver/ directory, unlike gdb/ where we use *.c, however, I was forgetting about the header files - we still use *.h for our C++ header files, so for now I left the settings in place to open all C files in c++-mode. We now have three copies of this file, which are all identical. It would be nice if we could remove this duplication, however, for now we haven't found a good way to do this. Some options considered were: 1. Use symlinks to only have one copy of the file. This was rejected as not all targets support symlinks in the way. 2. Have two of the .dir-locals.el files contain some mechanism by which the third copy of the file is sourced. Though this would, in theory, be possible, it would involve some advanced Emacs scripting, would be fragile, and a maintenance burdon. 3. Move the .dir-locals up into top level src/ directory, then use Emacs dir-locals directory pattern matching to only apply the rules for the three directories we care about. The problem is that each directory has to be listed separately, so we still end up having to duplicate all the rules. In the end, it was decided that having three copies of the file, though not ideal, is probably easiest for now. This was all discussed in this mailing list thread: https://sourceware.org/ml/gdb-patches/2020-03/msg00024.html The copyright date in the new files is left as for gdb/.dir-locals.el, as the new files are a copy of the old, this is inline with this rule: https://sourceware.org/gdb/wiki/ContributionChecklist#Copyright_Header gdb/ChangeLog: * .dir-locals.el: Add a comment referencing the other copies of this file. gdbserver/ChangeLog: * .dir-locals.el: New file. gdbsupport/ChangeLog: * .dir-locals.el: New file.

gdbsupport/configure.ac: source development.sh [Commit message by Simon Marchi] The GDB build in non-development mode (turn development to false in bfd/development.sh if you want to try) is currently broken: CXXLD gdb /home/smarchi/src/binutils-gdb/gdb/disasm-selftests.c:218: error: undefined reference to 'selftests::register_test_foreach_arch(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, void (*)(gdbarch*))' /home/smarchi/src/binutils-gdb/gdb/disasm-selftests.c:220: error: undefined reference to 'selftests::register_test_foreach_arch(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, void (*)(gdbarch*))' /home/smarchi/src/binutils-gdb/gdb/dwarf2/frame.c:2310: error: undefined reference to 'selftests::register_test_foreach_arch(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, void (*)(gdbarch*))' /home/smarchi/src/binutils-gdb/gdb/gdbarch-selftests.c:168: error: undefined reference to 'selftests::register_test_foreach_arch(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, void (*)(gdbarch*))' /home/smarchi/src/binutils-gdb/gdbsupport/selftest.cc:96: error: undefined reference to 'selftests::reset()' This is because the gdbsupport configure script doesn't source bfd/development.sh to set the development variable. When $development is unset, GDB_AC_SELFTEST defaults to enabling selftests. I don't think the macro was written with this intention in mind, it just happens to be that way. So gdbsupport thinks selftests are enabled, while gdb thinks they are disabled. gdbsupport compiles in code that calls selftests:: functions, which are normally provided by gdb, but gdb doesn't provide them, hence the undefined references. Fix this by sourcing bfd/development.sh in gdbsupport/configure.ac, so that the development variable is set. gdbsupport/ChangeLog: * configure.ac: Added call development.sh. * configure: Regenerate.

gdb, gdbserver, gdbsupport: add .gitattributes files Create .gitattributes files in gdb/, gdbserver/, and gdbsupport/. The files specify cpp-style diffs for .h and .c files. This is particularly helpful if a class in a header file is modified. For instance, if the `stop_requested` field of `thread_info` in gdb/gdbthread.h is modified, we get the following diff with 'git diff' (using git version 2.17.1): @@ -379,7 +379,7 @@ public: struct target_waitstatus pending_follow; /* True if this thread has been explicitly requested to stop. */ - int stop_requested = 0; + bool stop_requested = 0; /* The initiating frame of a nexting operation, used for deciding which exceptions to intercept.

If it is null_frame_id no The context is successfully shown as 'class thread_info'. This patch creates a .gitattributes file per each of gdb, gdbserver, and gdbsupport folders. An alternative would be to define the attributes in the root folder -- this would impact all the top-level folders, though. I opted for the more conservative approach. gdb/ChangeLog: 2020-03-05 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * .gitattributes: New file. gdbserver/ChangeLog: 2020-03-05 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * .gitattributes: New file. gdbsupport/ChangeLog: 2020-03-05 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * .gitattributes: New file.

Merge changes from GCC for the config/ directory GCC's config/ChangeLog since the last time this merge was done (in the binutils-gdb commit 0b4d000cc4e8e77c823) is included at the end of this commit message. It is worth noting that the binutils-gdb commit 301a9420d947da1458 added the file config/debuginfod.m4 which is not present in GCC's config/ directory. This file is preserved, unmodified, after this commit. In order to regenerate all of the configure files, I configured with --enable-maintainer-mode, and built the 'all' target. I then did the same thing on a source tree without this patch, and only committed those files that changed when this patch was added.

Fix gdbsupport build I'm seeing this on F27 (a clean build from scratch): ~~~~~~~~~~~~~~~~~~~~~~~~~~~ make[3]: Entering directory '/home/pedro/brno/pedro/gdb/binutils-gdb/build/gdbsupport' CC gdb_tilde_expand.o In file included from /home/pedro/gdb/binutils-gdb/src/gdbsupport/../gnulib/import/libc-config.h:33:0, from ../gnulib/import/glob.h:544, from /home/pedro/gdb/binutils-gdb/src/gdbsupport/gdb_tilde_expand.c:22: ../bfd/config.h:7:4: error: #error config.h must be #included before system headers # error config.h must be #included before system headers ^~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~ libc-config.h, where it includes config.h, says: ~~~~~~~~~~~~~~~~~~~~~~~~~~~ /* This is intended to be a good-enough substitute for glibc system macros like those defined in <sys/cdefs.h>, so that Gnulib code shared with glibc can do this as the first #include: #ifndef _LIBC # include <libc-config.h> #endif When compiled as part of glibc this is a no-op; when compiled as part of Gnulib this includes Gnulib's <config.h> and defines macros that glibc library code would normally assume. */ #include <config.h> ~~~~~~~~~~~~~~~~~~~~~~~~~~~ The issue is that that '#include <config.h>' picks up bfd's config.h instead of gnulib's. This problem doesn't trigger in the gdb dir because there we generate config.h under that exact name so gnulib's libc-config.h ends up picking gdb's config.h instead of gnulib.c and that ends up harmless. In gdbsupport, the config.h file is really named support-config.h, so that '#include <config.h>' in libc-config.h doesn't pick it like it would if it had the conventional config.h name. This patch fixes it by simply renaming gdbserver's support-config.h to config.h. gdbsupport/ChangeLog: 2020-01-17 Pedro Alves <palves@redhat.com> * configure.ac: Generate config.h instead of support-config.h. * common-defs.h: Include <gdbsupport/config.h> instead of <gdbsupport/support-config.h>. * Makefile.in: Regenerate. * configure: Regenerate.

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.
