| tree streamer_alloc_tree | ( | struct lto_input_block * | ib, |
| struct data_in * | data_in, | ||
| enum LTO_tags | tag | ||
| ) |
Materialize a new tree from input block IB using descriptors in DATA_IN. The code for the new tree should match TAG. Store in *IX_P the index into the reader cache where the new tree is stored.
We should never see an SSA_NAME tree. Only the version numbers of SSA names are ever written out. See input_ssa_names.
Instantiate a new tree using the header data.
For all other nodes, materialize the tree with a raw
make_node call.

inlinestatic |
Return true if tree node EXPR should be streamed as a builtin. For these nodes, we just emit the class and function code.

| void streamer_pack_tree_bitfields | ( | struct output_block * | ob, |
| struct bitpack_d * | bp, | ||

Pack all the bitfields in EXPR into a bit pack.
Note that all these functions are highly sensitive to changes in the types and sizes of each of the fields being packed.

read |
Read all the language-independent bitfield values for EXPR from IB. Return the partially unpacked bitpack so the caller can unpack any other bitfield values that the writer may have written.
Read the bitpack of non-pointer values from IB.
The first word in BP contains the code of the tree that we are about to read.
Unpack all the value fields from BP.

Read all pointer fields in EXPR from input block IB. DATA_IN contains tables and descriptors for the file being read.
| void streamer_tree_cache_append | ( | struct streamer_tree_cache_d * | cache, |
