	gcc/
	Add target hook invoked when cfun changes.

	* doc/tm.texi (TARGET_SET_CURRENT_FUNCTION): Document.
	* target.h (struct gcc_target): Add set_current_function.
	* target-def.h (TARGET_SET_CURRENT_FUNCTION): Define.
	(TARGET_INITIALIZER): Add initializer for set_current_function.
	* tree.h (push_struct_function): New.
	* tree-inline.h (push_cfun, pop_cfun): Move declarations to...
	* function.h: Here.
	(set_cfun): Declare.
	* tree-inline.c (cfun_stack, push_cfun, pop_cfun): Moved to...
	* function.c:  Here.
	(push_function_context_to): Use allocate_struct_function
	to create null context, not init_dummy_function_start.  Use set_cfun.
	(pop_function_context_from): Use set_cfun.
	(in_dummy_function): New.
	(invoke_set_current_function_hook): New.
	(set_cfun): New.
	(push_cfun, pop_cfun): Use set_cfun.
	(push_struct_function): New.
	(allocate_struct_function): Call invoke_set_current_function_hook
	before returning.
	(prepare_function_start): Don't set cfun here.  Remove unused
	argument; fix all callers.
	(init_dummy_function_start): Fiddle with in_dummy_function.  Call
	push_struct_function.
	(init_function_start): Set cfun here.
	(expand_dummy_function_end): Fiddle with in_dummy_function.  Pop cfun.
	* omp-low.c (create_omp_child_function): Use push_struct_function
	and pop_cfun to save/restore state.
	(expand_omp_parallel): Remove unused saved_cfun variable.
	* cgraphunit.c (ipa_passes): Use set_cfun.
	* gimple-low.c (record_vars_into): Use push_cfun/pop_cfun here.
	* dwarf2out.c (dwarf2out_abstract_function): Likewise.
	* matrix-reorg.c (transform_allocation_sites): Likewise.
	(matrix_reorg): Use set_cfun.
	* gimplify.c (gimplify_function_tree): Use push_cfun/pop_cfun here.
	* tree-optimize.c (tree_rest_of_compilation): Remove one redundant
	assignment to cfun; use set_cfun for the other.
	* tree-cfg.c (move_sese_region_to_fn): Use set_cfun.
	(dump_function_to_file): Use push_cfun/pop_cfun here.
	* c-decl.c (finish_function): Use set_cfun.

	gcc/ada/
	* trans.c (Compilation_unit_to_gnu): Use set_cfun.
	* utils.c (end_subprog_body): Likewise.

	gcc/cp/
	* decl.c (finish_function): Use set_cfun.
	* method.c (use_thunk): Likewise.

	gcc/fortran/
	* trans-decl.c (build_entry_thunks): Use set_cfun.
	(gfc_generate_function_code): Likewise.

	gcc/java/
	* decl.c (finish_method): Use set_cfun.

	gcc/treelang/
	* treetree.c (tree_code_create_function_wrapup):  Use set_cfun.
