Dmitry Antipov f3372c8789 Block-based vector allocation of small vectors. ... * src/lisp.h (struct vectorlike_header): New field `nbytes', adjust comment accordingly. * src/alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK' to denote vector blocks. Adjust users (live_vector_p, mark_maybe_pointer, valid_lisp_object_p) accordingly. (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG. (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES), (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX), (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST), (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros. (roundup_size): New constant. (struct vector_block): New data type. (vector_blocks, vector_free_lists, zero_vector): New variables. (all_vectors): Renamed to `large_vectors'. (allocate_vector_from_block, init_vectors, allocate_vector_from_block) (sweep_vectors): New functions. (allocate_vectorlike): Return `zero_vector' as the only vector of 0 items. Allocate new vector from block if vector size is less than or equal to VBLOCK_BYTES_MAX. (Fgarbage_collect): Move all vector sweeping code to sweep_vectors. (init_alloc_once): Add call to init_vectors. * doc/lispref/internals.text (Garbage Collection): Document new vector management code and vectorlike_header structure.		2012-06-08 12:44:30 +04:00
