| hashval_t | hash ) |
Appends tree node T to CACHE, even if T already existed in it.

◆ streamer_tree_cache_insert_1()
|
static |
Helper for streamer_tree_cache_insert and streamer_tree_cache_insert_at. CACHE, T, and IX_P are as in streamer_tree_cache_insert. If INSERT_AT_NEXT_SLOT_P is true, T is inserted at the next available slot in the cache. Otherwise, T is inserted at the position indicated in *IX_P. If T already existed in CACHE, return true. Otherwise, return false.

Table indexed by machine_mode, used for 2 different purposes. During streaming out we record there non-zero value for all modes that were streamed out. During streaming in, we translate the on the disk mode using this table. For normal LTO it is set to identity, for ACCEL_COMPILER depending on the mode_table content.
