Don't mark offload symbols with force_output in ltrans
2016-02-15 Tom de Vries <tom@codesourcery.com>
PR lto/69655
* lto-cgraph.c (input_offload_tables): Add and handle bool parameter
do_force_output.
* lto-streamer.h (input_offload_tables): Add and handle bool parameter.
* lto.c (read_cgraph_and_symbols): Call input_offload_tables with
argument.
