Change gdbserver to use existing gnulib and libiberty 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. ChangeLog 2020-02-14 Tom Tromey <tom@tromey.com> * Makefile.in: Rebuild. * Makefile.def: Make gdbserver require gnulib and libiberty. gdbserver/ChangeLog 2020-02-14 Tom Tromey <tom@tromey.com> * acinclude.m4: Don't include acx_configure_dir.m4. * Makefile.in (LIBIBERTY_BUILDDIR, GNULIB_BUILDDIR): Update. (SUBDIRS, CLEANDIRS, REQUIRED_SUBDIRS): Remove. (all, install-only, uninstall, clean-info, clean) (maintainer-clean): Don't recurse. (subdir_do, all-lib): Remove. ($(LIBGNU) $(LIBIBERTY) $(GNULIB_H)): Remove rule. (GNULIB_H): Remove. (generated_files): Update. ($(GNULIB_BUILDDIR)/Makefile): Remove rule. * configure: Rebuild. * configure.ac: Don't configure gnulib or libiberty. (GNULIB): Update. gdbsupport/ChangeLog 2020-02-14 Tom Tromey <tom@tromey.com> * common-defs.h: Change path to gnulib/config.h. Change-Id: I469cbbf5db2ab37109c058e9e3a1e4f4dabdfc98

gdbsupport: rename source files to .cc This patch renames the .c source files in gdbsupport to .cc. In the gdb directory, there is an argument against renaming the source files, which is that it makes using some git commands more difficult to do archeology. Some commands have some kind of "follow" option that makes git try to follow renames, but it doesn't work in all situations. Given that we have just moved the gdbsupport directory, that argument doesn't hold for source files in that directory. I therefore suggest renaming them to .cc, so that they are automatically recognized as C++ by various tools and editors. The original motivation behind this is that when building gdbsupport with clang, I get: CC agent.o clang: error: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated [-Werror,-Wdeprecated] In the gdb/ directory, we make clang happy by passing "-x c++". We could do this in gdbsupport too, but I think that renaming the files is a better long-term solution. gdbserver still does its own build of gdbsupport, so a few changes in its Makefile are necessary. gdbsupport/ChangeLog: * Makefile.am: Rename source files from .c to .cc. (CC, CFLAGS): Don't override. (AM_CFLAGS): Rename to ... (AM_CXXFLAGS): ... this. * Makefile.in: Re-generate. * %.c: Rename to %.cc. gdbserver/ChangeLog: * Makefile.in: Rename gdbsupport source files from .c to .cc.

Re-generate gdb/gdbserver/gdbsupport configure scripts 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.

Add -Wstrict-null-sentinel to gdbsupport/warning.m4 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.

Move gdb/warning.m4 to gdbsupport This file is used by gdbsupport, gdbserver and gdb, so I think it belongs in gdbsupport. Move it there and update the references the various acinclude.m4 files. gdbsupport/ChangeLog: * warning.m4: Move here, from gdb/warning.m4. * acinclude.m4: Update warning.m4 path. * Makefile.in: Re-generate. gdbserver/ChangeLog: * acinclude.m4: Update warning.m4 path. gdb/ChangeLog: * acinclude: Update warning.m4 path. * warning.m4: Move to gdbsupport.

gdbsupport: use AM_GDB_WARNINGS Since gdbsupport has been given its own build system, it is no longer compiled with the warning flags specified in gdb/warning.m4. This patch makes it use AM_GDB_WARNINGS. gdbsupport/ChangeLog: * acinclude.m4: Include ../gdb/warning.m4. * configure.ac: Use AM_GDB_WARNINGS. * Makefile.am: Set AM_CFLAGS to WARN_CFLAGS and WERROR_CFLAGS. * Makefile.in: Re-generate. * configure: Re-generate.

[gdb] Fix -Wstrict-null-sentinel warnings When passed in CXXFLAGS, -Wstrict-null-sentinel triggers twice in a gdb/gdbserver build. Fix the two occurrences. Build and reg-tested on x86_64-linux. gdb/ChangeLog: 2020-02-10 Tom de Vries <tdevries@suse.de> * dwarf2/read.c (process_psymtab_comp_unit_reader): Cast concat NULL sentinel to char *. gdbsupport/ChangeLog: 2020-02-10 Tom de Vries <tdevries@suse.de> * environ.c (gdb_environ::set): Cast concat NULL sentinel to char *.

Support the NetBSD version of pthread_setname_np On NetBSD, pthread_setname_np takes a printf-style format string plus one argument: https://netbsd.gw.com/cgi-bin/man-cgi?pthread_setname_np++NetBSD-current This patch makes thread-pool.c handle that. gdbsupport/ChangeLog: 2020-01-24 Christian Biesinger <cbiesinger@google.com> * thread-pool.c (set_thread_name): Add an overload for the NetBSD version of pthread_setname_np.

Fix gdbsupport build on compilers that don't default to C++11 or above gdbsupport fails to build with compilers that don't default to C++11 or above. gdbsupport's configure.ac is already using AX_CXX_COMPILE_STDCXX, which sets CXX_DIALECT to the -std=gnu++11 switch if necessary, but the problem is that nowhere are we using CXX_DIALECT. This fixes it. gdbsupport/ChangeLog: 2020-01-17 Pedro Alves <palves@redhat.com> * Makefile.am: Append CXX_DIALECT to CXX. * Makefile.in: Regenerate.

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.

Add gdbsupport check-defines script This adds a new script that tries to check that none of the support code uses defines that are not defined by common.m4. This check is necessarily inexact, but this script caught all the issues fixed in the previous patches. gdbsupport/ChangeLog 2020-01-14 Tom Tromey <tom@tromey.com> * Makefile.in: Rebuild. * Makefile.am (check-defines): New target. * check-defines.el: New file.

Move many configure checks to common.m4 This moves many needed configure checks from gdb and gdbserver into common.m4. This helps gdbsupport, nat, and target be self-contained. The result is a bit spaghetti-ish, because gdbsupport uses another m4 file from gdb/. The resulting code is somewhat non-obvious. However, these problems already exist, so it's not really that much worse than what is already done. gdb/ChangeLog 2020-01-14 Tom Tromey <tom@tromey.com> * configure: Rebuild. * configure.ac: Move many checks to ../gdbsupport/common.m4. gdb/gdbserver/ChangeLog 2020-01-14 Tom Tromey <tom@tromey.com> * configure: Rebuild. * configure.ac: Remove any checks that were added to common.m4. * acinclude.m4: Include lib-ld.m4, lib-prefix.m4, and lib-link.m4. gdbsupport/ChangeLog 2020-01-14 Tom Tromey <tom@tromey.com> * configure, Makefile.in, aclocal.m4, common.m4, config.in: Rebuild. * common.m4 (GDB_AC_COMMON): Move many checks from gdb/configure.ac. * acinclude.m4: Include bfd.m4, ptrace.m4.

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.
