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.
