2015-03-21 Tom de Vries <tom@codesourcery.com>
PR tree-optimization/65458
* cgraph.c (cgraph_node::dump): Handle parallelized_function field.
* cgraph.h (cgraph_node): Add parallelized_function field.
* lto-cgraph.c (lto_output_node): Write parallelized_function field.
(input_overwrite_node): Read parallelized_function field.
* omp-low.c (expand_omp_taskreg, finalize_task_copyfn): Set
parallelized_function on cgraph_node for child_fn.
* tree-parloops.c: Add include of plugin-api.h, ipa-ref.h and cgraph.h.
Remove include of gt-tree-parloops.h.
(parallelized_functions): Remove static variable.
(parallelized_function_p): Rewrite using parallelized_function field of
cgraph_node.
(create_loop_fn): Remove adding to parallelized_functions.
* Makefile.in (GTFILES): Remove tree-parloops.c
