Prune removed funcs from offload table
2017-12-30 Tom de Vries <tom@codesourcery.com>
PR libgomp/83046
* omp-expand.c (expand_omp_target): If in_lto_p, mark offload_funcs with
DECL_PRESERVE_P.
* lto-streamer-out.c (prune_offload_funcs): New function. Remove
offload_funcs entries that no longer have a corresponding cgraph_node.
Mark the remaining ones as DECL_PRESERVE_P.
(output_lto): Call prune_offload_funcs.
* testsuite/libgomp.oacc-c-c++-common/pr83046.c: New test.
* testsuite/libgomp.c-c++-common/pr83046.c: New test.
