The encoding for a function consists of the following sections:
1) The header.
2) FIELD_DECLS.
3) FUNCTION_DECLS.
4) global VAR_DECLS.
5) type_decls
6) types.
7) Names for the labels that have names
8) The SSA names.
9) The control flow graph.
10-11)Gimple for local decls.
12) Gimple for the function.
13) Strings.
1) THE HEADER.
2-6) THE GLOBAL DECLS AND TYPES.
The global decls and types are encoded in the same way. For each
entry, there is word with the offset within the section to the
entry.
7) THE LABEL NAMES.
Since most labels do not have names, this section my be of zero
length. It consists of an array of string table references, one
per label. In the lto code, the labels are given either
positive or negative indexes. the positive ones have names and
the negative ones do not. The positive index can be used to
find the name in this array.
9) THE CFG.
10) Index into the local decls. Since local decls can have local
decls inside them, they must be read in randomly in order to
properly restore them.
11-12) GIMPLE FOR THE LOCAL DECLS AND THE FUNCTION BODY.
The gimple consists of a set of records.
THE FUNCTION
At the top level of (8) is the function. It consists of five
pieces:
LTO_function - The tag.
eh tree - This is all of the exception handling regions
put out in a post order traversial of the
tree. Siblings are output as lists terminated
by a 0. The set of fields matches the fields
defined in except.cc.
last_basic_block - in uleb128 form.
basic blocks - This is the set of basic blocks.
zero - The termination of the basic blocks.
BASIC BLOCKS
There are two forms of basic blocks depending on if they are
empty or not.
The basic block consists of:
LTO_bb1 or LTO_bb0 - The tag.
bb->index - the index in uleb128 form.
#succs - The number of successors un uleb128 form.
the successors - For each edge, a pair. The first of the
pair is the index of the successor in
uleb128 form and the second are the flags in
uleb128 form.
the statements - A gimple tree, as described above.
These are only present for LTO_BB1.
Following each statement is an optional
exception handling record LTO_eh_region
which contains the region number (for
regions >= 0).
zero - This is only present for LTO_BB1 and is used
to terminate the statements and exception
regions within this block.
12) STRINGS
String are represented in the table as pairs, a length in ULEB128
form followed by the data for the string.

◆ lto_free_section_data_f
| typedef void lto_free_section_data_f(struct lto_file_decl_data *, enum lto_section_type, const char *, const char *, size_t) |
Return the data found from the above call. The first three parameters are the same as above. The fourth parameter is the data itself and the fifth is the length of the data.
◆ lto_get_section_data_f
| typedef const char * lto_get_section_data_f(struct lto_file_decl_data *, enum lto_section_type, const char *, int, size_t *) |
Return a char pointer to the start of a data stream for an lto pass or function. The first parameter is the file data that contains the information. The second parameter is the type of information to be obtained. The third parameter is the name of the function and is only used when finding a function body; otherwise it is NULL. The fourth parameter is the length of the data returned.

◆ lto_compression
| enum lto_compression |
◆ lto_decl_stream_e_t
| enum lto_decl_stream_e_t |
◆ lto_section_type
| enum lto_section_type |
Set of section types that are in an LTO file. This list will grow as the number of IPA passes grows since each IPA pass will need its own section type to store its summary information. When adding a new section type, you must also extend the LTO_SECTION_NAME array in lto-section-in.cc.
◆ LTO_tags
| enum LTO_tags |
Tags representing the various IL objects written to the bytecode file (GIMPLE statements, basic blocks, EH regions, tree nodes, etc). NOTE, when adding new LTO tags, also update lto_tag_name.

◆ compute_ltrans_boundary()
| lto_symtab_encoder_t compute_ltrans_boundary | ( | lto_symtab_encoder_t | in_encoder | ) |
Find all symbols we want to stream into given partition and insert them to encoders. The function actually replaces IN_ENCODER by new one. The reason is that streaming code needs clone's origin to be streamed before clone. This means that we need to insert the nodes in specific order. This order is ignored by the partitioning logic earlier.
