2020-10-31gdb: use AC_PROG_CC_STDC instead of AM_PROG_CC_STDCSimon Marchi1-1/+0
`autoconf -Wall` notes that AM_PROG_CC_STDC is obsolete: Fixes this autoconf warning: configure.ac:40: warning: 'AM_PROG_CC_STDC': this macro is obsolete. configure.ac:40: You should simply use the 'AC_PROG_CC' macro instead. configure.ac:40: Also, your code should no longer depend upon 'am_cv_prog_cc_stdc', configure.ac:40: but upon 'ac_cv_prog_cc_stdc'. aclocal.m4:770: AM_PROG_CC_STDC is expanded from... configure.ac:40: the top level Since we build with a C++ compiler now, I don't think this is relevant. If you look at the messages removed from gdbsupport/aclocal.m4, it says that this functionality is now integrated in AC_PROG_CC, which we already call. So it might not even make a difference. We had a local version of AM_PROG_CC_STDC, in gdb/acinclude.m4 (only used by gdb/configure.ac), remove it. gdb/ChangeLog: * acinclude.m4 (AM_PROG_CC_STDC): Remove. * configure: Re-generate. * configure.ac: Remove AM_PROG_CC_STDC. gdbsupport/ChangeLog: * aclocal.m4: Re-generate. * configure: Re-generate. * configure.ac: Remove AM_PROG_CC_STDC.

2020-10-31gdb, gdbserver, gdbsupport: use AC_CANONICAL_{BUILD,HOST,TARGET} instead of ↵Simon Marchi1-1/+10
AC_CANONICAL_SYSTEM `autoreconf -Wall` notes that AC_CANONICAL_SYSTEM is obsolete: configure.ac:36: warning: The macro `AC_CANONICAL_SYSTEM' is obsolete. Replace it by AC_CANONICAL_BUILD, AC_CANONICAL_HOST and AC_CANONICAL_TARGET in configure.ac files in gdb, gdbserver and gdbsupport. All three macros may not be needed everywhere, but it is hard to completely audit the configure files to see which are required, so I think it's better (and that there's no downside) to just call all three. gdb/ChangeLog: * configure.ac: Use AC_CANONICAL_{BUILD,HOST,TARGET} instead of AC_CANONICAL_SYSTEM. * configure: Re-generate. gdbserver/ChangeLog: * configure.ac: Use AC_CANONICAL_{BUILD,HOST,TARGET} instead of AC_CANONICAL_SYSTEM. * configure: Re-generate. gdbsupport/ChangeLog: * configure.ac: Use AC_CANONICAL_{BUILD,HOST,TARGET} instead of AC_CANONICAL_SYSTEM. * configure: Re-generate.

2020-03-12Move sourcing of development.sh to GDB_AC_COMMONSimon Marchi1-3/+0
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.
2020-03-05gdbsupport/configure.ac: source development.shVyacheslav Petrishchev1-0/+3
[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.
2020-02-11gdbsupport: use AM_GDB_WARNINGSSimon Marchi1-0/+3
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.
2020-01-17Fix gdbsupport buildPedro Alves1-1/+1
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.
2020-01-14Move many configure checks to common.m4Tom Tromey1-0/+3
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.

2020-01-14Move gdbsupport to the top levelTom Tromey1-0/+63
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.
