		enum lto_section_type	section_type,
		const char **	datar,
		size_t *	len
	)

read

Load a section of type SECTION_TYPE from FILE_DATA, parse the
   header and then return an input block pointing to the section.  The
   raw pointer to the section is returned in DATAR and LEN.  These are
   used to free the section.  Return NULL if the section is not present.

void lto_delete_in_decl_state ( )

Delete STATE and its components.

		enum lto_section_type	section_type,
		struct lto_input_block *	ib,
		const char *	data,
		size_t	len
	)

Close the section returned from a call to
   LTO_CREATE_SIMPLE_INPUT_BLOCK.  IB is the input block returned from
   that call.  The FILE_DATA and SECTION_TYPE are the same as what was
   passed to that call and the DATA and LEN are what was returned from
   that call.

int lto_eq_in_decl_state ( )

Return true if the fn_decl field of the lto_in_decl_state pointed to by
   P1 equals to the function decl P2.

void lto_free_section_data	(	struct lto_file_decl_data *	file_data,
		enum lto_section_type	section_type,
		const char *	name,
		const char *	data,
		size_t	len
	)

Free the data found from the above call.  The first three
   parameters are the same as above.  DATA is the data to be freed and
   LEN is the length of that data.

const char* lto_get_decl_name_mapping	(	struct lto_file_decl_data *	decl_data,
		const char *	name
	)

Given a string NAME, return the string that it has been mapped to
   by lto_record_renamed_decl.  If NAME was not renamed, it is
   returned unchanged.  DECL_DATA holds the renaming hash table to use.

		size_t *	len
	)

Return a char pointer to the start of a data stream for an LTO pass
   or function.  FILE_DATA indicates where to obtain the data.
   SECTION_TYPE is the type of information to be obtained.  NAME is
   the name of the function and is only used when finding a function
   body; otherwise it is NULL.  LEN is the size of the data
   returned.
