| 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) |

932 /* Fixed-size type macros */ |
| 428 | 933 /************************************************************************/ |
| 934 | |
| 935 /* For fixed-size types that are commonly used, we malloc() large blocks | |
| 936 of memory at a time and subdivide them into chunks of the correct | |
| 937 size for an object of that type. This is more efficient than | |
| 938 malloc()ing each object separately because we save on malloc() time | |
| 939 and overhead due to the fewer number of malloc()ed blocks, and | |
| 940 also because we don't need any extra pointers within each object | |
| 941 to keep them threaded together for GC purposes. For less common | |
| 942 (and frequently large-size) types, we use lcrecords, which are | |
| 943 malloc()ed individually and chained together through a pointer | |
| 944 in the lcrecord header. lcrecords do not need to be fixed-size | |
| 945 (i.e. two objects of the same type need not have the same size; | |
| 946 however, the size of a particular object cannot vary dynamically). | |
| 947 It is also much easier to create a new lcrecord type because no | |
| 948 additional code needs to be added to alloc.c. Finally, lcrecords | |
| 949 may be more efficient when there are only a small number of them. | |
| 950 | |
| 951 The types that are stored in these large blocks (or "frob blocks") | |
| 1983 | 952 are cons, all number types except fixnum, compiled-function, symbol, |
| 953 marker, extent, event, and string. | |
| 428 | 954 |
| 955 Note that strings are special in that they are actually stored in | |
| 956 two parts: a structure containing information about the string, and | |
| 957 the actual data associated with the string. The former structure | |
| 958 (a struct Lisp_String) is a fixed-size structure and is managed the | |
| 959 same way as all the other such types. This structure contains a | |
| 960 pointer to the actual string data, which is stored in structures of | |
| 961 type struct string_chars_block. Each string_chars_block consists | |
| 962 of a pointer to a struct Lisp_String, followed by the data for that | |
| 440 | 963 string, followed by another pointer to a Lisp_String, followed by |
| 964 the data for that string, etc. At GC time, the data in these | |
| 965 blocks is compacted by searching sequentially through all the | |
| 428 | 966 blocks and compressing out any holes created by unmarked strings. |
| 967 Strings that are more than a certain size (bigger than the size of | |
| 968 a string_chars_block, although something like half as big might | |
| 969 make more sense) are malloc()ed separately and not stored in | |
| 970 string_chars_blocks. Furthermore, no one string stretches across | |
| 971 two string_chars_blocks. | |
| 972 | |
| 1204 | 973 Vectors are each malloc()ed separately as lcrecords. |
| 428 | 974 |
| 975 In the following discussion, we use conses, but it applies equally | |
| 976 well to the other fixed-size types. | |
| 977 | |
| 978 We store cons cells inside of cons_blocks, allocating a new | |
| 979 cons_block with malloc() whenever necessary. Cons cells reclaimed | |
| 980 by GC are put on a free list to be reallocated before allocating | |
| 981 any new cons cells from the latest cons_block. Each cons_block is | |
| 982 just under 2^n - MALLOC_OVERHEAD bytes long, since malloc (at least | |
| 983 the versions in malloc.c and gmalloc.c) really allocates in units | |
| 984 of powers of two and uses 4 bytes for its own overhead. | |
| 985 | |
| 986 What GC actually does is to search through all the cons_blocks, | |
| 987 from the most recently allocated to the oldest, and put all | |
| 988 cons cells that are not marked (whether or not they're already | |
| 989 free) on a cons_free_list. The cons_free_list is a stack, and | |
| 990 so the cons cells in the oldest-allocated cons_block end up | |
| 991 at the head of the stack and are the first to be reallocated. | |
| 992 If any cons_block is entirely free, it is freed with free() | |
| 993 and its cons cells removed from the cons_free_list. Because | |
| 994 the cons_free_list ends up basically in memory order, we have | |
| 995 a high locality of reference (assuming a reasonable turnover | |
| 996 of allocating and freeing) and have a reasonable probability | |
| 997 of entirely freeing up cons_blocks that have been more recently | |
| 998 allocated. This stage is called the "sweep stage" of GC, and | |
| 999 is executed after the "mark stage", which involves starting | |
| 1000 from all places that are known to point to in-use Lisp objects | |
| 1001 (e.g. the obarray, where are all symbols are stored; the | |
| 1002 current catches and condition-cases; the backtrace list of | |
| 1003 currently executing functions; the gcpro list; etc.) and | |
| 1004 recursively marking all objects that are accessible. | |
| 1005 | |
| 454 | 1006 At the beginning of the sweep stage, the conses in the cons blocks |
| 1007 are in one of three states: in use and marked, in use but not | |
| 1008 marked, and not in use (already freed). Any conses that are marked | |
| 1009 have been marked in the mark stage just executed, because as part | |
| 1010 of the sweep stage we unmark any marked objects. The way we tell | |
| 1011 whether or not a cons cell is in use is through the LRECORD_FREE_P | |
| 1012 macro. This uses a special lrecord type `lrecord_type_free', | |
| 1013 which is never associated with any valid object. | |
| 1014 | |
| 1015 Conses on the free_cons_list are threaded through a pointer stored | |
| 1016 in the conses themselves. Because the cons is still in a | |
| 1017 cons_block and needs to remain marked as not in use for the next | |
| 1018 time that GC happens, we need room to store both the "free" | |
| 1019 indicator and the chaining pointer. So this pointer is stored | |
| 1020 after the lrecord header (actually where C places a pointer after | |
| 1021 the lrecord header; they are not necessarily contiguous). This | |
| 1022 implies that all fixed-size types must be big enough to contain at | |
| 1023 least one pointer. This is true for all current fixed-size types, | |
| 1024 with the possible exception of Lisp_Floats, for which we define the | |
| 1025 meat of the struct using a union of a pointer and a double to | |
| 1026 ensure adequate space for the free list chain pointer. | |
| 428 | 1027 |
| 1028 Some types of objects need additional "finalization" done | |
| 1029 when an object is converted from in use to not in use; | |
| 1030 this is the purpose of the ADDITIONAL_FREE_type macro. | |
| 1031 For example, markers need to be removed from the chain | |
| 1032 of markers that is kept in each buffer. This is because | |
| 1033 markers in a buffer automatically disappear if the marker | |
| 1034 is no longer referenced anywhere (the same does not | |
| 1035 apply to extents, however). | |
| 1036 | |
| 1037 WARNING: Things are in an extremely bizarre state when | |
| 1038 the ADDITIONAL_FREE_type macros are called, so beware! | |
| 1039 | |
| 454 | 1040 When ERROR_CHECK_GC is defined, we do things differently so as to |
| 1041 maximize our chances of catching places where there is insufficient | |
| 1042 GCPROing. The thing we want to avoid is having an object that | |
| 1043 we're using but didn't GCPRO get freed by GC and then reallocated | |
| 1044 while we're in the process of using it -- this will result in | |
| 1045 something seemingly unrelated getting trashed, and is extremely | |
| 1046 difficult to track down. If the object gets freed but not | |
| 1047 reallocated, we can usually catch this because we set most of the | |
| 1048 bytes of a freed object to 0xDEADBEEF. (The lisp object type is set | |
| 1049 to the invalid type `lrecord_type_free', however, and a pointer | |
| 1050 used to chain freed objects together is stored after the lrecord | |
| 1051 header; we play some tricks with this pointer to make it more | |
| 428 | 1052 bogus, so crashes are more likely to occur right away.) |
| 1053 | |
| 1054 We want freed objects to stay free as long as possible, | |
| 1055 so instead of doing what we do above, we maintain the | |
| 1056 free objects in a first-in first-out queue. We also | |
| 1057 don't recompute the free list each GC, unlike above; | |
| 1058 this ensures that the queue ordering is preserved. | |
| 1059 [This means that we are likely to have worse locality | |
| 1060 of reference, and that we can never free a frob block | |
| 1061 once it's allocated. (Even if we know that all cells | |
| 1062 in it are free, there's no easy way to remove all those | |
| 1063 cells from the free list because the objects on the | |
| 1064 free list are unlikely to be in memory order.)] | |
| 1065 Furthermore, we never take objects off the free list | |
| 1066 unless there's a large number (usually 1000, but | |
| 1067 varies depending on type) of them already on the list. | |
| 1068 This way, we ensure that an object that gets freed will | |
| 1069 remain free for the next 1000 (or whatever) times that | |
| 440 | 1070 an object of that type is allocated. */ |
