27
|
|
|
28 FSF: Original version; a long time ago.
|
|
|
29 Mly: Significantly rewritten to use new 3-bit tags and
|
|
|
30 nicely abstracted object definitions, for 19.8.
|
|
|
31 JWZ: Improved code to keep track of purespace usage and
|
|
|
32 issue nice purespace and GC stats.
|
|
|
33 Ben Wing: Cleaned up frob-block lrecord code, added error-checking
|
|
|
34 and various changes for Mule, for 19.12.
|
|
|
35 Added bit vectors for 19.13.
|
|
|
36 Added lcrecord lists for 19.14.
|
|
|
37 slb: Lots of work on the purification and dump time code.
|
|
|
38 Synched Doug Lea malloc support from Emacs 20.2.
|
|
442
|
39 og: Killed the purespace. Portable dumper (moved to dumper.c)

814 size for an object of that type. This is more efficient than
|
|
|
815 malloc()ing each object separately because we save on malloc() time
|
|
|
816 and overhead due to the fewer number of malloc()ed blocks, and
|
|
|
817 also because we don't need any extra pointers within each object
|
|
|
818 to keep them threaded together for GC purposes. For less common
|
|
|
819 (and frequently large-size) types, we use lcrecords, which are
|
|
|
820 malloc()ed individually and chained together through a pointer
|
|
|
821 in the lcrecord header. lcrecords do not need to be fixed-size
|
|
|
822 (i.e. two objects of the same type need not have the same size;
|
|
|
823 however, the size of a particular object cannot vary dynamically).
|
|
|
824 It is also much easier to create a new lcrecord type because no
|
|
|
825 additional code needs to be added to alloc.c. Finally, lcrecords
|
|
|
826 may be more efficient when there are only a small number of them.
|
|
|
827
|
|
|
828 The types that are stored in these large blocks (or "frob blocks")
|
|
1983
|
829 are cons, all number types except fixnum, compiled-function, symbol,
|
|
|
830 marker, extent, event, and string.
|
|
428
|
831
|
|
|
832 Note that strings are special in that they are actually stored in
|
|
|
833 two parts: a structure containing information about the string, and
|
|
|
834 the actual data associated with the string. The former structure
|
|
|
835 (a struct Lisp_String) is a fixed-size structure and is managed the
|
|
|
836 same way as all the other such types. This structure contains a
|
|
|
837 pointer to the actual string data, which is stored in structures of
|
|
|
838 type struct string_chars_block. Each string_chars_block consists
|
|
|
839 of a pointer to a struct Lisp_String, followed by the data for that
|
|
440
|
840 string, followed by another pointer to a Lisp_String, followed by
|
|
|
841 the data for that string, etc. At GC time, the data in these
|
|
|
842 blocks is compacted by searching sequentially through all the
|
|
428
|
843 blocks and compressing out any holes created by unmarked strings.
|
|
|
844 Strings that are more than a certain size (bigger than the size of
|
|
|
845 a string_chars_block, although something like half as big might
|
|
|
846 make more sense) are malloc()ed separately and not stored in
|
|
|
847 string_chars_blocks. Furthermore, no one string stretches across
|
|
|
848 two string_chars_blocks.
|
|
|
849
|
|
1204
|
850 Vectors are each malloc()ed separately as lcrecords.
|
|
428
|
851
|
|
|
852 In the following discussion, we use conses, but it applies equally
|
|
|
853 well to the other fixed-size types.
|
|
|
854
|
|
|
855 We store cons cells inside of cons_blocks, allocating a new
|
|
|
856 cons_block with malloc() whenever necessary. Cons cells reclaimed
|
|
|
857 by GC are put on a free list to be reallocated before allocating
|
|
|
858 any new cons cells from the latest cons_block. Each cons_block is
|
|
|
859 just under 2^n - MALLOC_OVERHEAD bytes long, since malloc (at least
|
|
|
860 the versions in malloc.c and gmalloc.c) really allocates in units
|
|
|
861 of powers of two and uses 4 bytes for its own overhead.
|
|
|
862
|
|
|
863 What GC actually does is to search through all the cons_blocks,
|
|
|
864 from the most recently allocated to the oldest, and put all
|
|
|
865 cons cells that are not marked (whether or not they're already
|
|
|
866 free) on a cons_free_list. The cons_free_list is a stack, and
|
|
|
867 so the cons cells in the oldest-allocated cons_block end up
|
|
|
868 at the head of the stack and are the first to be reallocated.
|
|
|
869 If any cons_block is entirely free, it is freed with free()
|
|
|
870 and its cons cells removed from the cons_free_list. Because
|
|
|
871 the cons_free_list ends up basically in memory order, we have
|
|
|
872 a high locality of reference (assuming a reasonable turnover
|
|
|
873 of allocating and freeing) and have a reasonable probability
|
|
|
874 of entirely freeing up cons_blocks that have been more recently
|
|
|
875 allocated. This stage is called the "sweep stage" of GC, and
|
|
|
876 is executed after the "mark stage", which involves starting
|
|
|
877 from all places that are known to point to in-use Lisp objects
|
|
|
878 (e.g. the obarray, where are all symbols are stored; the
|
|
|
879 current catches and condition-cases; the backtrace list of
|
|
|
880 currently executing functions; the gcpro list; etc.) and
|
|
|
881 recursively marking all objects that are accessible.
|
|
|
882
|
|
454
|
883 At the beginning of the sweep stage, the conses in the cons blocks
|
|
|
884 are in one of three states: in use and marked, in use but not
|
|
|
885 marked, and not in use (already freed). Any conses that are marked
|
|
|
886 have been marked in the mark stage just executed, because as part
|
|
|
887 of the sweep stage we unmark any marked objects. The way we tell
|
|
|
888 whether or not a cons cell is in use is through the LRECORD_FREE_P
|
|
|
889 macro. This uses a special lrecord type `lrecord_type_free',
|
|
|
890 which is never associated with any valid object.
|
|
|
891
|
|
|
892 Conses on the free_cons_list are threaded through a pointer stored
|
|
|
893 in the conses themselves. Because the cons is still in a
|
|
|
894 cons_block and needs to remain marked as not in use for the next
|
|
|
895 time that GC happens, we need room to store both the "free"
|
|
|
896 indicator and the chaining pointer. So this pointer is stored
|
|
|
897 after the lrecord header (actually where C places a pointer after
|
|
|
898 the lrecord header; they are not necessarily contiguous). This
|
|
|
899 implies that all fixed-size types must be big enough to contain at
|
|
|
900 least one pointer. This is true for all current fixed-size types,
|
|
|
901 with the possible exception of Lisp_Floats, for which we define the
|
|
|
902 meat of the struct using a union of a pointer and a double to
|
|
|
903 ensure adequate space for the free list chain pointer.
|
|
428
|
904
|
|
|
905 Some types of objects need additional "finalization" done
|
|
|
906 when an object is converted from in use to not in use;
|
|
|
907 this is the purpose of the ADDITIONAL_FREE_type macro.
|
|
|
908 For example, markers need to be removed from the chain
|
|
|
909 of markers that is kept in each buffer. This is because
|
|
|
910 markers in a buffer automatically disappear if the marker
|
|
|
911 is no longer referenced anywhere (the same does not
|
|
|
912 apply to extents, however).
|
|
|
913
|
|
|
914 WARNING: Things are in an extremely bizarre state when
|
|
|
915 the ADDITIONAL_FREE_type macros are called, so beware!
|
|
|
916
|
|
454
|
917 When ERROR_CHECK_GC is defined, we do things differently so as to
|
|
|
918 maximize our chances of catching places where there is insufficient
|
|
|
919 GCPROing. The thing we want to avoid is having an object that
|
|
|
920 we're using but didn't GCPRO get freed by GC and then reallocated
|
|
|
921 while we're in the process of using it -- this will result in
|
|
|
922 something seemingly unrelated getting trashed, and is extremely
|
|
|
923 difficult to track down. If the object gets freed but not
|
|
|
924 reallocated, we can usually catch this because we set most of the
|
|
|
925 bytes of a freed object to 0xDEADBEEF. (The lisp object type is set
|
|
|
926 to the invalid type `lrecord_type_free', however, and a pointer
|
|
|
927 used to chain freed objects together is stored after the lrecord
|
|
|
928 header; we play some tricks with this pointer to make it more
|
|
428
|
929 bogus, so crashes are more likely to occur right away.)
|
|
|
930
|
|
|
931 We want freed objects to stay free as long as possible,
|
|
|
932 so instead of doing what we do above, we maintain the
|
|
|
933 free objects in a first-in first-out queue. We also
|
|
|
934 don't recompute the free list each GC, unlike above;
|
|
|
935 this ensures that the queue ordering is preserved.
|
|
|
936 [This means that we are likely to have worse locality
|
|
|
937 of reference, and that we can never free a frob block
|
|
|
938 once it's allocated. (Even if we know that all cells
|
|
|
939 in it are free, there's no easy way to remove all those
|
|
|
940 cells from the free list because the objects on the
|
|
|
941 free list are unlikely to be in memory order.)]
|
|
|
942 Furthermore, we never take objects off the free list
|
|
|
943 unless there's a large number (usually 1000, but
|
|
|
944 varies depending on type) of them already on the list.
|
|
|
945 This way, we ensure that an object that gets freed will
|
|
|
946 remain free for the next 1000 (or whatever) times that
|
|
440
|
947 an object of that type is allocated. */

4695 It seems that the following holds:

4696

4697 1. When using the old allocator (malloc.c):
|
|
|
4698
|
|
|
4699 -- blocks are always allocated in chunks of powers of two. For
|
|
|
4700 each block, there is an overhead of 8 bytes if rcheck is not
|
|
|
4701 defined, 20 bytes if it is defined. In other words, a
|
|
|
4702 one-byte allocation needs 8 bytes of overhead for a total of
|
|
|
4703 9 bytes, and needs to have 16 bytes of memory chunked out for
|
|
|
4704 it.
|
|
|
4705
|
|
|
4706 2. When using the new allocator (gmalloc.c):
|
|
|
4707
|
|
|
4708 -- blocks are always allocated in chunks of powers of two up
|
|
|
4709 to 4096 bytes. Larger blocks are allocated in chunks of
|
|
|
4710 an integral multiple of 4096 bytes. The minimum block
|
|
|
4711 size is 2*sizeof (void *), or 16 bytes if SUNOS_LOCALTIME_BUG
|
|
|
4712 is defined. There is no per-block overhead, but there
|
|
|
4713 is an overhead of 3*sizeof (size_t) for each 4096 bytes
|
|
|
4714 allocated.
|
|
|
4715
|
|
|
4716 3. When using the system malloc, anything goes, but they are
|
|
|
4717 generally slower and more space-efficient than the GNU
|
|
|
4718 allocators. One possibly reasonable assumption to make
|
|
|
4719 for want of better data is that sizeof (void *), or maybe
|
|
|
4720 2 * sizeof (void *), is required as overhead and that
|
|
|
4721 blocks are allocated in the minimum required size except
|
|
|
4722 that some minimum block size is imposed (e.g. 16 bytes). */
