(1) printing_unreadable_object -> printing_unreadable_object_fmt.
(2) printing_unreadable_lcrecord -> printing_unreadable_lisp_object
and fix up so it no longer requires an lcrecord.
These previous changes eliminate most of the remaining places where
the terms `lcrecord' and `lrecord' occurred outside of specialized
code.
(3) Fairly major change: Reduce the number of words in an lcrecord
from 3 to 2. The third word consisted of a uid that duplicated the
lrecord uid, and a single free bit, which was moved into the lrecord
structure. This reduces the size of the `uid' slot from 21 bits to
20 bits. Arguably this isn't enough -- we could easily have more than
1,000,000 or so objects created in a session. The answer is
(a) It doesn't really matter if we overflow the uid field because
it's only used for debugging, to identify an object uniquely
(or pretty much so).
(b) If we cared about it overflowing and wanted to reduce this,
we could make it so that cons, string, float and certain other
frob-block types that never print out the uid simply don't
store a uid in them and don't increment the lrecord_uid_counter.
(4) In conjunction with (3), create new macro NORMAL_LISP_OBJECT_UID()
and use it to abstract out the differences between NEWGC and old-GC
in accessing the `uid' value from a "normal Lisp Object pointer".
(5) In events.c, use zero_nonsized_lisp_object() in place of custom-
written equivalent. In font-mgr.c use external_object_printer()
in place of custom-written equivalents.

| 30 Based on code from pre-release FSF 19, c. 1991. | |
| 31 Various changes by Jamie Zawinski 1991-1994: | |
| 32 converting to ANSI C, splitting out function prototypes to a separate | |
| 33 file (later moved back for unknown reasons by Steve Baur?), debug-gcpro | |
| 34 stuff (now moribund). | |
| 35 ANSI-fication of DEFUN macros by Felix Lee, c. 1992? | |
| 36 NOT_REACHED, DOESNT_RETURN, PRINTF_ARGS by Richard Mlynarik, c. 1994. | |
| 37 Many changes over the years corresponding to Lisp_Object definition | |
| 38 changes, esp. by Richard Mlynarik (c. 1993) and Kyle Jones (c. 1998). | |
| 39 See alloc.c for more details. | |
| 40 Overhauled and reordered by Ben Wing, 1995-1996, and many things added: | |
| 41 Dynarrs, REALLOC macros, asserts, typedefs, inline header code, | |
| 42 first LIST_LOOP macros, CONCHECK_*, all error-checking code | |
| 43 (e.g. error-checking versions of XFOO macros), structure read syntax, | |
| 44 weak lists, lcrecord lists, reworking of quit handling, object hashing, | |
| 45 nested GCPRO, character objects and Ebola checking, memory usage stats, | |
| 46 others. | |
| 47 LOADHIST changes from Steve Baur, c. 1997? | |
| 48 Various macro-related changes by Martin Buchholz, 1998-1999: | |
| 49 LIST_LOOP macros greatly expanded and tortoise-hared; | |
| 50 RETURN_SANS_WARNINGS; reworked DEFUN macros; EXFUN macros (???). | |
| 1743 | 51 Various macro-related changes by Jerry James, 2003: |
| 52 MODULE_API introduced; | |
| 53 Compiler-specific definitions modernized and moved to compiler.h. | |

| 58 "Mule-izing" is the process of going through a file and eliminating | |
| 59 assumptions that the internal format (Ibyte * text) is the same as the | |
| 60 external format used by library routines. Mule-ization should also | |
| 61 include replacing *ALL* raw references to `char' or `unsigned char' with | |
| 62 one of the self-documenting types created below. How exactly to do the | |
| 63 conversion, and how to write correctly Mule-ized code, is described in | |
| 64 the internals manual. Files that say "This file is Mule-ized" have | |
| 65 been reviewed at some point; that's not to say that incorrect code hasn't | |
| 66 crept in, though. | |
| 67 | |
| 68 "Unicode-splitting" is the process of fixing a file so that it will | |
| 69 handle external text in Unicode under Microsoft Windows, as appropriate. | |
| 70 ("splitting" because it needs to handle either Unicode or variable-width | |
| 71 multibyte depending on the OS -- NT or 9x). See intl-win32.c. | |
| 72 | |
| 73 #### is a way of marking problems of any sort. | |
| 74 | |
| 75 !!#### marks places that are not properly Mule-ized. | |
| 76 | |
| 77 &&#### marks places that need to be fixed in order for the "8-bit mule" | |
| 78 conversion to work correctly, i.e. in order to support multiple different | |
| 79 buffer formats under Mule, including a fixed 8-bit format. | |
| 80 | |
| 81 ^^#### marks places that need to be fixed in order to eliminate the | |
| 82 assumption that Ibyte * text is composed of 1-byte units (e.g. UTF-16 | |
| 83 is composed of 2-byte units and might be a possible format to consider | |
| 84 for Ibyte * text). | |
| 85 | |
| 86 %%#### marks places that need work for KKCC (the new garbage collector). | |
| 87 | |
| 5090 | 88 @@#### marks places that need work to get Unicode-internal working, |
| 89 i.e. using UTF-8 as the internal text format. | |
| 90 | |
| 91 #### BILL! marks places that need work for GTK. | |
| 92 | |
| 93 #### GEOM! marks places needing work to fix various bugs in the handling | |
| 94 of window and frame sizing and positioning. Often the root of the | |
| 95 problems is that the code was originally written before there was a | |
| 96 gutter and then not completely fixed up to accommodate the gutter. | |

| 851 | 1311 We provide MALLOC_OR_ALLOCA() below for places where it's likely that |
| 1312 large amounts will be allocated; it mallocs the block if it's too big. | |
| 1313 Unfortunately, that requires a call to unbind_to() at the end of the | |
| 1314 function, and it's not feasible to rewrite all calls to alloca() this | |
| 1315 way. | |
| 1316 | |
| 1317 Instead, we use the portable C alloca() substitute in alloca.c above a | |
| 1318 certain size. This actually uses malloc(), but checks the current stack | |
| 1319 pointer to see if data from previous alloca() calls needs to be freed. | |
| 1320 However, this can lead to large heap sizes -- especially since cleanup | |
| 1321 can only happen in a parent function, and will never happen if (as will | |
| 1322 often be the case) it's the same function in the same place in the code | |
| 1323 that keeps tripping the alloca() limit. | |
| 1324 | |
| 1325 So we set up a system to periodically force cleanup. Currently we | |
| 1326 do cleanup: | |
| 1327 | |
| 1328 -- Only when there's C alloca() data, and then | |
| 1329 -- Every stack alloca() or allocation of Lisp data, every call to | |
| 1330 next_event_internal() [typically near the top of the stack], | |
| 1331 or every 10th funcall | |
| 1332 | |
| 1333 This should not be a big penalty because | |
| 1334 | |
| 1335 (a) If there are few C alloca() chunks, checking them will be fast | |
| 1336 (b) If not, we've allocated a huge amount of heap space (remember, each | |
| 1337 chunk represents > 256K of heap), and we really want them gone | |

| 1786 | |
| 5038 | 1787 /* Dynarr locking and verification. |
| 1788 | |
| 1789 [I] VERIFICATION | |
| 1790 | |
| 1791 Verification routines simply return their basic argument, possibly | |
| 1792 casted, but in the process perform some verification on it, aborting if | |
| 1793 the verification fails. The verification routines take FILE and LINE | |
| 1794 parameters, and use them to output the file and line of the caller | |
| 1795 when an abort occurs, rather than the file and line of the inline | |
| 1796 function, which is less than useful. | |
| 1797 | |
| 1798 There are three basic types of verification routines: | |
| 1799 | |
| 1800 (1) Verify the dynarr itself. This verifies the basic invariant | |
| 1801 involving the length/size values: | |
| 1802 | |
| 1803 0 <= Dynarr_length(d) <= Dynarr_largest(d) <= Dynarr_max(d) | |
| 1804 | |
| 1805 (2) Verify the dynarr itself prior to modifying it. This performs | |
| 1806 the same verification as previously, but also checks that the | |
| 1807 dynarr is not locked (see below). | |
| 1808 | |
| 1809 (3) Verify a dynarr position. Unfortunately we have to have | |
| 1810 different verification routines depending on which kind of operation | |
| 1811 is being performed: | |
| 1812 | |
| 1813 (a) For Dynarr_at(), we check that the POS is bounded by Dynarr_largest(), | |
| 1814 i.e. 0 <= POS < Dynarr_largest(). | |
| 1815 (b) For Dynarr_atp_allow_end(), we also have to allow | |
| 1816 POS == Dynarr_largest(). | |
| 1817 (c) For Dynarr_atp(), we behave largely like Dynarr_at() but make a | |
| 1818 special exception when POS == 0 and Dynarr_largest() == 0 -- see | |
| 1819 comment below. | |
| 1820 (d) Some other routines contain the POS verification within their code, | |
| 1821 and make the check 0 <= POS < Dynarr_length() or | |
| 1822 0 <= POS <= Dynarr_length(). | |
| 1823 | |
| 1824 #### It is not well worked-out whether and in what circumstances it's | |
| 1825 allowed to use a position that is between Dynarr_length() and | |
| 1826 Dynarr_largest(). The ideal solution is to never allow this, and require | |
| 1827 instead that code first change the length before accessing higher | |
| 1828 positions. That would require looking through all the code that accesses | |
| 1829 dynarrs and fixing it appropriately (especially redisplay code, and | |
| 1830 especially redisplay code in the vicinity of a reference to | |
| 1831 Dynarr_largest(), since such code usually checks explicitly to see whether | |
| 1832 there is extra stuff between Dynarr_length() and Dynarr_largest().) | |
| 1833 | |
| 1834 [II] LOCKING | |
| 1835 | |
| 1836 The idea behind dynarr locking is simple: Locking a dynarr prevents | |
| 1837 any modification from occurring, or rather, leads to an abort upon | |
| 1838 any attempt to modify a dynarr. | |
| 1839 | |
| 1840 Dynarr locking was originally added to catch some sporadic and hard-to- | |
| 1841 debug crashes in the redisplay code where dynarrs appeared to be getting | |
| 1842 corrupted in an unexpected fashion. The solution was to lock the | |
| 1843 dynarrs that were getting corrupted (in this case, the display-line | |
| 1844 dynarrs) around calls to routines that weren't supposed to be changing | |
| 1845 these dynarrs but might somehow be calling code that modified them. | |
| 1846 This eventually revealed that there was a reentrancy problem with | |
| 1847 redisplay that involved the QUIT mechanism and the processing done in | |
| 1848 order to determine whether C-g had been pressed -- this processing | |
| 1849 involves retrieving, processing and queueing pending events to see | |
| 1850 whether any of them result in a C-g keypress. However, at least under | |
| 1851 MS Windows this can result in redisplay being called reentrantly. | |

| 442 | 2540 /*---------------------- list traversal macros -------------------------*/ |
| 2541 | |
| 2542 /* Note: These macros are for traversing through a list in some format, | |
| 2543 and executing code that you specify on each member of the list. | |
| 2544 | |
| 2545 There are two kinds of macros, those requiring surrounding braces, and | |
| 2546 those not requiring this. Which type of macro will be indicated. | |
| 2547 The general format for using a brace-requiring macro is | |
| 2548 | |
| 2549 { | |
| 2550 LIST_LOOP_3 (elt, list, tail) | |
| 2551 execute_code_here; | |
| 2552 } | |
| 2553 | |
| 2554 or | |
| 2555 | |
| 2556 { | |
| 2557 LIST_LOOP_3 (elt, list, tail) | |
| 2558 { | |
| 2559 execute_code_here; | |
| 2560 } | |
| 2561 } | |
| 2562 | |
| 2563 You can put variable declarations between the brace and beginning of | |
| 2564 macro, but NOTHING ELSE. | |
| 2565 | |
| 2566 The brace-requiring macros typically declare themselves any arguments | |
| 2567 that are initialized and iterated by the macros. If for some reason | |
| 2568 you need to declare these arguments yourself (e.g. to do something on | |
| 2569 them before the iteration starts, use the _NO_DECLARE versions of the | |
| 2570 macros.) | |
| 2571 */ | |
| 2572 | |
| 2573 /* There are two basic kinds of macros: those that handle "internal" lists | |
| 2574 that are known to be correctly structured (i.e. first element is a cons | |
| 2575 or nil, and the car of each cons is also a cons or nil, and there are | |
| 2576 no circularities), and those that handle "external" lists, where the | |
| 2577 list may have any sort of invalid formation. This is reflected in | |
| 2578 the names: those with "EXTERNAL_" work with external lists, and those | |
| 2579 without this prefix work with internal lists. The internal-list | |
| 2580 macros will hit an assertion failure if the structure is ill-formed; | |
| 2581 the external-list macros will signal an error in this case, either a | |
| 2582 malformed-list error or a circular-list error. | |
| 2583 */ | |
| 2584 | |

| 2586 surrounding, and iterates through a list, which may or may not known to | |
| 2587 be syntactically correct. It accepts two args, TAIL (set progressively | |
| 2588 to each cons starting with the first), and LIST, the list to iterate | |
| 2589 over. TAIL needs to be defined by the caller. | |
| 442 | 2590 |
| 2591 In each iteration, you can retrieve the current list item using XCAR | |
| 2592 (tail), or destructively modify the list using XSETCAR (tail, | |

| 2603 | |
| 2604 LIST_LOOP_2 and EXTERNAL_LIST_LOOP_2 are the standard, most-often used | |
| 2605 macros. They take two arguments, an element variable ELT and the list | |
| 2606 LIST. ELT is automatically declared, and set to each element in turn | |
| 2607 from LIST. | |
| 2608 | |
| 2609 LIST_LOOP_3 and EXTERNAL_LIST_LOOP_3 are the same, but they have a third | |
| 2610 argument TAIL, another automatically-declared variable. At each iteration, | |
| 2611 this one points to the cons cell for which ELT is the car. | |
| 2612 | |
| 2613 EXTERNAL_LIST_LOOP_4 is like EXTERNAL_LIST_LOOP_3 but takes an additional | |
| 2614 LEN argument, again automatically declared, which counts the number of | |
| 2615 iterations gone by. It is 0 during the first iteration. | |
| 2616 | |
| 2617 EXTERNAL_LIST_LOOP_4_NO_DECLARE is like EXTERNAL_LIST_LOOP_4 but none | |
| 2618 of the variables are automatically declared, and so you need to declare | |
| 2619 them yourself. (ELT and TAIL are Lisp_Objects, and LEN is an EMACS_INT.) | |

| 3841 /* DEFUN - Define a built-in Lisp-visible C function or `subr'. | |
| 3842 `lname' should be the name to give the function in Lisp, | |
| 3843 as a null-terminated C string. | |
| 3844 `Fname' should be the C equivalent of `lname', using only characters | |
| 3845 valid in a C identifier, with an "F" prepended. | |
| 3846 The name of the C constant structure that records information | |
| 3847 on this function for internal use is "S" concatenated with Fname. | |
| 3848 `min_args' should be a number, the minimum number of arguments allowed. | |
| 3849 `max_args' should be a number, the maximum number of arguments allowed, | |
| 3850 or else MANY or UNEVALLED. | |
| 3851 MANY means pass a vector of evaluated arguments, | |
| 3852 in the form of an integer number-of-arguments | |
| 3853 followed by the address of a vector of Lisp_Objects | |
| 3854 which contains the argument values. | |
| 3855 UNEVALLED means pass the list of unevaluated arguments. | |
| 3856 `prompt' says how to read arguments for an interactive call. | |
| 3857 See the doc string for `interactive'. | |
| 3858 A null string means call interactively with no arguments. | |
| 3859 `arglist' are the comma-separated arguments (always Lisp_Objects) for | |
| 3860 the function. | |
| 3861 The docstring for the function is placed as a "C" comment between | |
| 3862 the prompt and the `args' argument. make-docfile reads the | |
| 3863 comment and creates the DOC file from it. | |

| 4270 Fformat() should format the untranslated args[0] and return that, | |
| 4271 and also call Fgettext() on args[0] and, if that is different, | |
| 4272 format it and store it in the `string-translatable' property of the | |
| 4273 returned string. See Fgettext(). | |

| 4393 | |
| 4394 The C++ code below catches GCPRO without UNGCPRO or vice-versa. | |
| 4395 Catching cases where there's no GCPRO or UNGCPRO but should be, however, | |
| 4396 is much harder, but could be done: | |
| 4397 | |
| 4398 1. Lisp_Object becomes a real object. Its creator and destructor need to | |
| 4399 figure out whether the object is on the stack (by looking at the range | |
| 4400 that `this' is within), and if so, add the pointer to a list of all | |
| 4401 stack-based Lisp_Objects. | |
| 4402 | |
| 4403 2. The assignment method needs to do reference-counting on actual Lisp | |
| 4404 objects -- in particular, we need to know if there are any references | |
| 4405 to a Lisp object that are *NOT* from stack-based Lisp_Objects. | |
| 4406 | |
| 4407 3. When we get to a point in the code where we might garbage collect -- | |
| 4408 i.e. Ffuncall(), Feval(), or Fgarbage_collect() is called -- we look | |
| 4409 at our list of stack-based Lisp_Objects, and if there are any that | |
| 4410 point to Lisp objects with no non-stack references, see if there are | |
| 4411 any gcpros pointing to the object, and if not, set a flag indicating | |
| 4412 that the object is "destroyed". (Don't abort yet because the function | |
| 4413 might not use the object any more.) | |
| 4414 | |
| 4415 4. When we detag a pointer using XFOO(), abort if its "destroyed" flag | |
| 4416 is set. | |
