Remove some redundant functions, change others to labels, lisp/
lisp/ChangeLog addition:
2012-05-05 Aidan Kehoe <kehoea@parhasard.net>

labels, avoiding visibility in the global namespace, and reducing
the size of the dumped binary.

Use incf, decf, plusp, minusp and the more general argument type
checking macros.
* lib-complete.el:
* lib-complete.el (lib-complete:better-root): Changed to a label.
* lib-complete.el (lib-complete:get-completion-table): Changed to
a label.
* lib-complete.el (read-library-internal): Include labels.
* lib-complete.el (lib-complete:cache-completions): Changed to a
label.
* minibuf.el (read-buffer): Use #'set-difference, don't reinvent it.
* newcomment.el (comment-padright): Use a label instead of
repeating a lambda expression.
* packages.el (package-get-key):
* packages.el (package-get-key-1): Removed, use #'getf instead.
* simple.el (kill-backward-chars): Removed; this isn't used.
* simple.el (what-cursor-position):
(lambda (arg) (format "%S" arg) -> #'prin1-to-string.
* simple.el (debug-print-1): Renamed to #'debug-print.
* simple.el (debug-print): Removed, #'debug-print-1 was equivalent.

longer available.

6 | |
992 | 7 New KKCC-GC mark algorithm: |
8 configure flag : --use-kkcc | |
9 | |
10 For better understanding, first a few words about the mark algorithm | |
11 up to now: | |
12 Every Lisp_Object has its own mark method, which calls mark_object | |
13 with the stuff to be marked. | |
1598 | 14 Also, many Lisp_Objects have pdump descriptions memory_descriptions, |
15 which are used by the portable dumper. The dumper gets all the | |
16 information it needs about the Lisp_Object from the descriptions. | |
992 | 17 |
18 Also the garbage collector can use the information in the pdump | |
19 descriptions, so we can get rid of the mark methods. | |
20 That is what we have been doing. | |
21 | |
22 | |
23 DUMPABLE FLAG | |
24 ------------- | |
25 First we added a dumpable flag to lrecord_implementation. It shows, | |
26 if the object is dumpable and should be processed by the dumper. | |
27 The dumpable flag is the third argument of a lrecord_implementation | |
28 definition (DEFINE_LRECORD_IMPLEMENTATION). | |
29 If it is set to 1, the dumper processes the descriptions and dumps | |
30 the Object, if it is set to 0, the dumper does not care about it. | |
31 | |
32 | |
1598 | 33 KKCC MARKING |
34 ------------ | |
35 All Lisp_Objects have memory_descriptions now, so we could get | |
36 rid of the mark_object calls. | |
37 The KKCC algorithm manages its own stack. Instead of calling | |
38 mark_object, all the alive Lisp_Objects are pushed on the | |
39 kkcc_gc_stack. Then these elements on the stack are processed | |
40 according to their descriptions. | |
41 | |
42 | |
992 | 43 TODO |
44 ---- | |
1598 | 45 - For weakness use weak datatypes instead of XD_FLAG_NO_KKCC. |
46 XD_FLAG_NO_KKCC occurs in: | |
47 * elhash.c: htentry | |
48 * extents.c: lispobject_gap_array, extent_list, extent_info | |
49 * marker.c: marker | |
50 Not everything has to be rewritten. See Ben's comment in lrecord.h. | |
51 - Clean up special case marking (weak_hash_tables, weak_lists, | |
52 ephemerons). | |
53 - Stack optimization (have one stack during runtime instead of | |
54 malloc/free it for every garbage collect) | |

56 There are a few Lisp_Objects, where there occurred differences and |
1204 | 57 inexactness between the mark-method and the pdump description. All |
58 these Lisp_Objects get dumped (except image instances), so their | |
59 descriptions have been written, before we started our work: | |
992 | 60 * alloc.c: string |
1598 | 61 description: size_, data_, and plist is described |
62 mark: only plist is marked, but flush_cached_extent_info is called. | |
63 flush_cached_extent_info -> | |
64 free_soe -> | |
65 free_extent_list -> | |
66 free_gap_array -> | |
67 gap_array_delete_all_markers -> | |
68 Add gap_array to the gap_array_marker_freelist | |
992 | 69 |
1204 | 70 * glyphs.c: image_instance |
1598 | 71 description: device is not set to nil |
1204 | 72 mark: mark method sets device to nil if dead |
1598 | 73 See comment above the description. |
