        PR c++/27574
        * gcc/cgraph.c (cgraph_remove_node): Do not remove the body of
          abstract functions. It might be useful to emit debugging
          information. This is a patch from Ian Lance Taylor.
        * cgraphunit.c (cgraph_optimize): Do not cry when bodies of abstract
          functions are still around. They are useful to output debug info.
