◆ add_node_to()

Add NODE into encoder as well as nodes it is cloned from. Do it in a way so clones appear first.

◆ 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.

Overwrite the information in NODE based on FILE_DATA, TAG, FLAGS, STACK_SIZE, SELF_TIME and SELF_SIZE.

BP is a bitpack with all the bitflags for NODE read from the stream. Initialize HAS_THUNK_INFO to indicate if thunk info should be streamed in.

WRITTEN_DECLS is the set of FUNCTION_DECLs that have had their callgraph node written so far. This is used to determine if NODE is a clone of a previously written node.

◆ output_offload_tables()
| void output_offload_tables | ( | void | ) |
Output function/variable tables that will allow libgomp to look up offload target code. OFFLOAD_FUNCS is filled in expand_omp_target, OFFLOAD_VARS is filled in varpool_node::get_create. In WHOPR (partitioned) mode during the WPA stage both OFFLOAD_FUNCS and OFFLOAD_VARS are filled by input_offload_tables.
