Fix performance regression in refactored syntax cache setup.
More doc improvements.
* syntax.h (enum syntax_source):
New. Specify whether syntax is from property or buffer.
(struct syntax_cache):
Use enum syntax_source source, instead of no_syntax_table_prop
and use_code.
Improve comments.
(SOURCE_IS_TABLE):
New predicate.
(SYNTAX_CODE_FROM_CACHE):
Use it instead of use_code, and adjust logic.
* syntax.c (syntax_cache_table_was_changed):
Check cache->source (cache->no_syntax_table_prop is gone).
(reset_syntax_cache_range):
All information about OBJECT and BUFFER is in CACHE already.
Also reset markers in OBJECT if it is a buffer.
Rename INFINITE to VALID_EVERYWHERE.
(init_syntax_cache):
Initialize source (cache->no_syntax_table_prop is gone).
Maybe initialize start and end to null markers.
Initialize cache range with reset_syntax_cache_range.
(update_syntax_cache):
Use source instead of no_syntax_table_prop and use_code.
(setup_syntax_cache):
Add header comment. Improve other comments.
Make calls to reset_syntax_cache_range and init_syntax_cache match
their prototypes.
(init_buffer_syntax_cache):
Use init_syntax_cache to do the work.
(signal_syntax_cache_extent_changed):
Make call to reset_syntax_cache_range match its prototype.
Improve local variable naming.

The files of Emacs are written so as to have no initialized data that can ever need to be altered except at the first startup. This is so that those words can be dumped as sharable text. It is not possible to exercise such control over library files. So it is necessary to refrain from making their data areas shared. Therefore, this file is loaded following all the files of Emacs but before library files. As a result, the symbol my_edata indicates the point in data space between data coming from Emacs and data coming from libraries. */ #include <config.h> char my_edata[] = "End of Emacs initialized data"; /* Ensure there is enough slack in the .bss to pad with. */ #ifdef HEAP_IN_DATA #define BSS_PADDING 0x1000 #else #define BSS_PADDING 1 #endif char my_ebss [BSS_PADDING];
