2020-03-12Change gdbserver to use existing gdbsupportTom Tromey1-3/+4
This changes the gdbserver build to use the gdbsupport that was built for gdb. gdbserver and gdbreplay now must use WIN32APILIBS (aka -lws2_32). Before this change, gdbserver did not define USE_WIN32API when building gdbsupport, but now this is always done. ChangeLog 2020-03-12 Tom Tromey <tom@tromey.com> * Makefile.in: Rebuild. * Makefile.def (gdbserver): Depend on gdbsupport. gdbserver/ChangeLog 2020-03-12 Tom Tromey <tom@tromey.com> * configure: Rebuild. * configure.ac (GDBSERVER_DEPFILES): Remove srv_selftest_objs.

2020-03-12Fix gdbserver build when intl already builtTom Tromey1-0/+83
gdbserver uses gdb's alloc.c, and this in turn can include headers from intl via gdbsupport/gdb_locale.h. This can cause build failures in some situations, for example if you build gdb and gdbserver on mingw. This patch restores the gdbsupport dependency on intl, and changes gdbserver to use ZW_GNU_GETTEXT_SISTER_DIR. This fixes this build problem. ChangeLog 2020-03-12 Tom Tromey <tom@tromey.com> * Makefile.in: Rebuild. * Makefile.def (gdbsupport): Depend on intl. gdbserver/ChangeLog 2020-03-12 Tom Tromey <tom@tromey.com> * config.in, configure: Rebuild. * configure.ac: Call ZW_GNU_GETTEXT_SISTER_DIR. * acinclude.m4: Include gettext-sister.m4. * Makefile.in (top_builddir, INTL, INTL_DEPS, INTL_CFLAGS): New variables.

2020-03-12Move sourcing of development.sh to GDB_AC_COMMONSimon Marchi1-435/+436
The same is done for gdb, gdbserver and gdbsupport. I therefore think it makes sense to move that to GDB_AC_COMMON. It is required to move the call to GDB_AC_COMMON so it is before GDB_AC_SELFTEST in gdbserver/configure.ac, otherwise the $development variable isn't set when the code behind GDB_AC_SELFTEST executes. gdb/ChangeLog: * configure.ac: Don't source bfd/development.sh. * selftest.m4: Modify comment. * configure: Re-generate. gdbserver/ChangeLog: * configure.ac: Don't source bfd/development.sh, move GDB_AC_COMMON higher. * configure: Re-generate. gdbsupport/ChangeLog: * configure.ac: Don't source bfd/development.sh. * common.m4: Source bfd/development.sh. * configure: Re-generate.
2020-03-12gdb/selftest.m4: ensure $development is setSimon Marchi1-0/+5
Before commit 3d1e5a43cbe ("gdbsupport/configure.ac: source development.sh"), the GDB build in non-development mode (turn development to false in bfd/development.sh if you want to try) was broken because the gdbsupport configure script didn't source bfd/development.sh to set the development variable. Since the GDB_AC_SELFTEST macro relies on the `development` variable, I propose to modify it such that it errors out if $development does not have an expected value of "true" or "false". This could prevent a future similar problem from happening while refactoring the configure scripts. It would have caught the problem fixed by the patch mentioned earlier. gdb/ChangeLog: * selftest.m4 (GDB_AC_SELFTEST): Error out if $development is not "true" or "false". * configure: Re-generate. gdbserver/ChangeLog: * configure: Re-generate. gdbsupport/ChangeLog: * configure: Re-generate.
2020-03-11gdb: enable -Wmissing-prototypes warningSimon Marchi1-0/+1
While compiling with clang, I noticed it didn't catch cases where my function declaration didn't match my function definition. This is normally caught by gcc with -Wmissing-declarations. On clang, this is caught by -Wmissing-prototypes instead. Note that on gcc, -Wmissing-prototypes also exists, but is only valid for C and Objective-C. It gets correctly rejected by the configure script since gcc rejects it with: cc1plus: error: command line option '-Wmissing-prototypes' is valid for C/ObjC but not for C++ -Werror So this warning flag ends up not used for gcc (which is what we want). gdb/ChangeLog: * configure: Re-generate. gdbserver/ChangeLog: * configure: Re-generate. gdbsupport/ChangeLog: * configure: Re-generate. * warning.m4: Enable -Wmissing-prototypes.
2020-02-19Merge changes from GCC for the config/ directoryAndrew Burgess1-6/+23
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.

2020-02-14Change gdbserver to use existing gnulib and libibertyTom Tromey1-218/+1
This changes gdbserver so that it no longer builds its own gnulib and libiberty. Instead, it now relies on the ones that were already built at the top level. gdbsupport is still built specially for gdbserver. This is more complicated and will be tackled in a subsequent patch.

2020-02-13gdbserver: rename source files to .ccSimon Marchi1-1/+1
For the same reasons outlined in the previous patch, this patch renames gdbserver source files to .cc. I have moved the "-x c++" switch to only those rules that require it. gdbserver/ChangeLog: * Makefile.in: Rename source files from .c to .cc. * %.c: Rename to %.cc. * configure.ac: Rename server.c to server.cc. * configure: Re-generate.
2020-02-11Re-generate gdb/gdbserver/gdbsupport configure scriptsSimon Marchi1-1/+2
In my previous commit, I did a last minute modification of warning.m4, but forgot to re-generate the configure scripts, this commit fixes that. gdb/ChangeLog: * configure: Re-generate. gdbserver/ChangeLog: * configure: Re-generate. gdbsupport/ChangeLog: * configure: Re-generate.
2020-02-11Add -Wstrict-null-sentinel to gdbsupport/warning.m4Simon Marchi1-1/+2
Commit 85f0dd3ce ("[gdb] Fix -Wstrict-null-sentinel warnings") fixed some violations of -Wstrict-null-sentinel. If we want to enforce this warning, I think we should enable it in our warning.m4 file. gdbsupport/ChangeLog: * warning.m4: Add -Wstrict-null-sentinel. * configure: Re-generate. gdbserver/ChangeLog: * configure: Re-generate. gdb/ChangeLog: * configure: Re-generate.
2020-02-07Move gdbserver to top levelTom Tromey1-0/+12159
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.
