bool gate_lto_out ( void )

Gate function for all LTO streaming passes.

References seen_error().

bitmap lto_bitmap_alloc ( void )

Allocate a bitmap from heap.  Initializes the LTO obstack if necessary.

References bitmap_obstack_initialize(), and lto_obstack_initialized.

Referenced by lto_output().

void lto_bitmap_free ( )

Free bitmap B.

Referenced by lto_output().

void lto_check_version ( )

Check that the version MAJOR.MINOR is the correct version number.

References fatal_error().

Referenced by lto_input_toplevel_asms(), and lto_read_body().

char* lto_get_section_name ( )

Get a section name for a particular type or name.  The NAME field
   is only used if SECTION_TYPE is LTO_section_function_body. For all
   others it is ignored.  The callee of this function is responsible
   to free the returned name.

intptr_t lto_orig_address_get ( )

Get the original address of T as it was seen by the writer.  This
   is only valid while T is being reconstructed.

References hash_table< Descriptor, Allocator >::find_slot(), tree_hash_entry::key, and tree_hash_entry::value.

void lto_orig_address_map ( )

Add a mapping between T and ORIG_T, which is the numeric value of
   the original address of T as it was seen by the LTO writer.  This
   mapping is useful when debugging streaming problems.  A debugging
   session can be started on both reader and writer using ORIG_T
   as a breakpoint value in both sessions.

   Note that this mapping is transient and only valid while T is
   being reconstructed.  Once T is fully built, the mapping is
   removed.

void lto_orig_address_remove ( )

Clear the mapping of T to its original address.

void lto_streamer_hooks_init ( void )

Initialize all the streamer hooks used for streaming GIMPLE.

void lto_streamer_init ( void )

Initialization common to the LTO reader and writer.

Show various memory usage statistics related to LTO.

bitmap_obstack lto_obstack

LTO uses bitmaps with different life-times.  So use a separate
   obstack for all LTO bitmaps.
