tree cilk_arrow	(	tree	,
		int	,
		bool
	)

tree cilk_call_setjmp ( tree )

tree cilk_dot	(	tree	,
		int	,
		bool
	)

void cilk_init_builtins ( void )

Creates and initializes all the built-in Cilk keywords functions and three structures: __cilkrts_stack_frame, __cilkrts_pedigree and __cilkrts_worker. Detailed information about __cilkrts_stack_frame and __cilkrts_worker structures are given in libcilkrts/include/internal/abi.h. __cilkrts_pedigree is described in libcilkrts/include/cilk/common.h.

 Now build the following __cilkrts_pedigree struct:
 struct __cilkrts_pedigree {
    uint64_t rank;
    struct __cilkrts_pedigree *parent;
  }

 Build the Cilk Stack Frame:
 struct __cilkrts_stack_frame {
   uint32_t flags;
   uint32_t size;
   struct __cilkrts_stack_frame *call_parent;
   __cilkrts_worker *worker;
   void *except_data;
   void *ctx[4];
   uint32_t mxcsr;
   uint16_t fpcsr;
   uint16_t reserved;
   __cilkrts_pedigree pedigree;
 };

 Now add them to a common structure whose fields are #defined to something
 that is used at a later stage.

 We don't care about reserved, so no need to store it in cilk_trees.

 Now let's do the following worker struct:

 struct __cilkrts_worker {
   __cilkrts_stack_frame *volatile *volatile tail;
   __cilkrts_stack_frame *volatile *volatile head;
   __cilkrts_stack_frame *volatile *volatile exc;
   __cilkrts_stack_frame *volatile *volatile protected_tail;
   __cilkrts_stack_frame *volatile *ltq_limit;
   int32_t self;
   global_state_t *g;
   local_state *l;
   cilkred_map *reducer_map;
   __cilkrts_stack_frame *current_stack_frame;
   void *reserved;
   __cilkrts_worker_sysdep_state *sysdep;
   __cilkrts_pedigree pedigree;
}

 void __cilkrts_enter_frame_1 (__cilkrts_stack_frame *);

 void __cilkrts_enter_frame_fast_1 (__cilkrts_stack_frame *);

 void __cilkrts_pop_frame (__cilkrts_stack_frame *);

 void __cilkrts_leave_frame (__cilkrts_stack_frame *);

 void __cilkrts_sync (__cilkrts_stack_frame *);

 void __cilkrts_detach (__cilkrts_stack_frame *);

 __cilkrts_rethrow (struct stack_frame *);

 __cilkrts_save_fp_ctrl_state (__cilkrts_stack_frame *);

void expand_builtin_cilk_detach ( tree )

void expand_builtin_cilk_pop_frame ( tree )

bool fn_contains_cilk_spawn_p ( )

inline

Returns true if Cilk Plus is enabled and if F->cilk_frame_decl is not NULL_TREE.
