clang gives this warning: ..../gdb/unittests/environ-selftests.c:139:7: error: explicitly moving variable of type 'gdb_environ' to itself [-Werror,-Wself-move] env = std::move (env); ~~~ ^ ~~~ Ignoring the warning locally is the right thing to do, since it warns about behavior we want to unit test, while an explicit self-move in real code would likely be a mistake that we'd want to catch. To avoid cluttering the code with preprocessor conditionals, this commit adds the file common/diagnostics.h, in which we can put macros used to control compiler diagnostics. GCC enhancement request here: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81159 gdb/ChangeLog: 2017-06-22 Pedro Alves <palves@redhat.com> Simon Marchi <simon.marchi@ericsson.com> * unittests/environ-selftests.c (run_tests): Ignore -Wself-move warning. * common/diagnostics.h: New file.
