| 418 A `closed' endpoint of a range means that the number at that end is included | |
| 419 in the range. For an `open' endpoint, the number would not be included. | |
| 420 | |
| 421 For example, a closed-open range from 5 to 20 would be indicated as [5, | |
| 422 20) where a bracket indicates a closed end and a parenthesis an open end, | |
| 423 and would mean `all the numbers between 5 and 20', including 5 but not 20. | |
| 424 This seems a little strange at first but is in fact extremely common in | |
| 425 the outside world as well as in computers and makes things work sensibly. | |
| 426 For example, if I say "there are seven days between today and next week | |
| 427 today", I'm including today but not next week today; if I included both, | |
| 428 there would be eight days. Similarly, there are 15 (= 20 - 5) elements in | |
| 429 the range [5, 20), but 16 in the range [5, 20]. | |

| 891 /* A "unified range table" is a format for storing range tables | |
| 892 as contiguous blocks of memory. This is used by the regexp | |
| 893 code, which needs to use range tables to properly handle [] | |
| 894 constructs in the presence of extended characters but wants to | |
| 895 store an entire compiled pattern as a contiguous block of memory. | |
| 896 | |
| 897 Unified range tables are designed so that they can be placed | |
| 898 at an arbitrary (possibly mis-aligned) place in memory. | |
| 899 (Dealing with alignment is a pain in the ass.) | |
| 900 | |
| 901 WARNING: No provisions for garbage collection are currently made. | |
| 902 This means that there must not be any Lisp objects in a unified | |
| 903 range table that need to be marked for garbage collection. | |
| 904 Good candidates for objects that can go into a range table are | |
| 905 | |
| 906 -- numbers and characters (do not need to be marked) | |
| 907 -- nil, t (marked elsewhere) | |
| 908 -- charsets and coding systems (automatically marked because | |
| 909 they are in a marked list, | |
| 910 and can't be removed) | |
| 911 | |
| 912 Good but slightly less so: | |
| 913 | |
| 914 -- symbols (could be uninterned, but that is not likely) | |
| 915 | |
| 916 Somewhat less good: | |
| 917 | |
| 918 -- buffers, frames, devices (could get deleted) | |
| 919 | |
| 920 | |
| 921 It is expected that you work with range tables in the normal | |
| 922 format and then convert to unified format when you are done | |
| 923 making modifications. As such, no functions are provided | |
| 924 for modifying a unified range table. The only operations | |
| 925 you can do to unified range tables are | |
| 926 | |
| 927 -- look up a value | |
| 928 -- retrieve all the ranges in an iterative fashion | |
| 929 | |
| 930 */ | |
| 931 | |
| 932 /* The format of a unified range table is as follows: | |
| 933 | |
| 934 -- The first byte contains the number of bytes to skip to find the | |
| 935 actual start of the table. This deals with alignment constraints, | |
| 936 since the table might want to go at any arbitrary place in memory. | |
| 937 -- The next three bytes contain the number of bytes to skip (from the | |
| 938 *first* byte) to find the stuff after the table. It's stored in | |
| 939 little-endian format because that's how God intended things. We don't | |
| 940 necessarily start the stuff at the very end of the table because | |
| 941 we want to have at least ALIGNOF (EMACS_INT) extra space in case | |
| 942 we have to move the range table around. (It appears that some | |
| 943 architectures don't maintain alignment when reallocing.) | |
