I need to use this cleanup logic for the testsuite for libdiagnostics where it's too awkward to directly use gcc-dg.exp itself. No functional change intended. gcc/testsuite/ChangeLog: * lib/dg-test-cleanup.exp: New file, from material moved from lib/gcc-dg.exp. * lib/gcc-dg.exp: Add load_lib of dg-test-cleanup.exp. (cleanup-after-saved-dg-test): Move to lib/dg-test-cleanup.exp. (dg-test): Likewise for override. (initialize_prune_notes): Likewise. libatomic/ChangeLog: * testsuite/lib/libatomic.exp: Add "load_gcc_lib dg-test-cleanup.exp". libgomp/ChangeLog: * testsuite/lib/libgomp.exp: Add "load_gcc_lib dg-test-cleanup.exp". libitm/ChangeLog: * testsuite/lib/libitm.exp: Add "load_gcc_lib dg-test-cleanup.exp". libphobos/ChangeLog: * testsuite/lib/libphobos-dg.exp: Add "load_gcc_lib dg-test-cleanup.exp". libstdc++-v3/ChangeLog: * testsuite/lib/libstdc++.exp: Add "load_gcc_lib dg-test-cleanup.exp". libvtv/ChangeLog: * testsuite/lib/libvtv.exp: Add "load_gcc_lib dg-test-cleanup.exp".
