◆ stream_write_tree_ref()
| void stream_write_tree_ref | ( | struct output_block * | ob, |

Output reference to tree T to the stream. Assume that T is already in encoder cache. This is used to stream tree bodies where we know the DFS walk arranged everything to cache. Must be matched with stream_read_tree_ref.

Emit the chain of tree nodes starting at T. OB is the output block to write to. REF_P is true if chain elements should be emitted as references.

◆ subtract_estimated_size()
Very rough estimate of streaming size of the initializer. If we ignored presence of strings, we could simply just count number of non-indexable tree nodes and number of references to indexable nodes. Strings however may be very large and we do not want to dump them int othe global stream. Count the size of initializer until the size in DATA is positive.

◆ tree_is_indexable()
Return true if tree node T is written to various tables. For these nodes, we sometimes want to write their phyiscal representation (via lto_output_tree), and sometimes we need to emit an index reference into a table (via lto_output_tree_ref).

◆ write_global_stream()
|
static |
Write each node in encoded by ENCODER to OB, as well as those reachable from it and required for correct representation of its semantics. Each node in ENCODER must be a global declaration or a type. A node is written only once, even if it appears multiple times in the vector. Certain transitively-reachable nodes, such as those representing expressions, may be duplicated, but such nodes must not appear in ENCODER itself.
