libgcc2.c (__empty): An empty function used by the C++ frontend for defaulting cleanup actions.
* libgcc2.c (__empty): An empty function used by the C++ frontend for
defaulting cleanup actions.
* tree.c (save_tree_status, restore_tree_status): Save and restore
temporary_firstobj, so that in progress objects that live on the
temporary obstack are not reallocated, if we save and restore the
tree status in their lifetime.
