This is the final patch to add frozen variable objects. It includes testsuite changes and documentation. Since the time I've posted the first version the code has seen some extra testing, and basically works fine. The only change is that now the "frozen=1" fields is only output for frozen variable objects and "frozen=0" is never output. This is to avoid adjusting everything single use of -var-create in the testsuite. This patch depends on some of my previously posted patches, namely: - mi_continue_to cleanup - varobj doc cleanup - simplified MI tests OK? - Volodya gdb/ * varobj.h (varobj_set_frozen): New (varobj_get_frozen): New. (varobj_update): New parameter explicit. * varobj.c (struct varobj): New fields frozen and not_fetched. (varobj_set_frozen, varobj_get_frozen): New. (install_new_value): Don't fetch values for frozen variable object, or children thereof. Allow a frozen variable object to have non-fetched value. (varobj_update): Allow updating child variables. Don't traverse frozen children. (new_variable): Initialize the frozen field. (c_value_of_variable): Return NULL for frozen variable without any value yet. * mi/mi-cmd-var.c (varobj_update_one): New parameter 'explicit'. (mi_cmd_var_create): Output the 'frozen' field, as soon as testsuite is adjusted to expect that field. (mi_cmd_var_set_frozen): New. (mi_cmd_var_update): Pass the 'explicit' parameter to varobj_update_one. * mi/mi-cmds.c (mi_cmds): Register '-var-set-frozen'. * mi/mi-cmds.h (mi_cmd_var_set_frozen): Declare. doc/ * gdb.texinfo (GDB/MI Variable Objects): Document frozen variables objects. testsuite/ * gdb.mi/mi-var-cmd.exp: Delete varobjs left by previous tests. Run the frozen varobjs test. * gdb.mi/var-cmd.c (do_frozen_tests): New. * lib/mi-support.exp (mi_varobj_delete): New. (mi_varobj_update): Fix thinko.
