Add parameter to allow enabling/disabling selftests via configure 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. OK? gdb/ChangeLog: 2018-10-10 Sergio Durigan Junior <sergiodj@redhat.com> Simon Marchi <simark@simark.ca> * README (`configure' options): Add documentation for new "--enable-unit-tests" option. * acinclude.m4: Include "selftest.m4". * configure: Regenerate. * configure.ac: Use "GDB_AC_SELFTEST". * maint.c (maintenance_selftest): Update message informing that selftests have been disabled.

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.

gdb: Require C++11 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. Makefile:9451: recipe for target 'configure-gdb' failed make[1]: *** [configure-gdb] Error 1 make[1]: Leaving directory '/home/pedro/brno/pedro/gdb/mygit/cxx-convertion/build-gcc-4.7' If we need to revert back to making C++11 optional, all that's necessary is to change the "mandatory" to "optional" in configure.ac and regenerate configure (both gdb and gdbserver). gdb/ChangeLog: 2016-10-28 Pedro Alves <palves@redhat.com> * Makefile.in (CXX_DIALECT): Get from configure.
