Be better about bounds-checking, #'subseq, #'fill; add same, #'reduce.
2010-09-16 Aidan Kehoe <kehoea@parhasard.net>
* fns.c (Fsubseq):
Change the string code to better fit in with the rest of this
function (it still uses get_string_range_char(), though, which *may*
diverge algorithmically from what we're doing).
If dealing with a cons, only call #'length if we have reason to
believe that the START and END arguments are badly specified, and
check for circular lists ourselves when that's appropriate.
If dealing with a vector, call Fvector() on the appropriate subset
of the old vector's data directly, don't initialise the result
with nil and then copy.
(Ffill):
Only check the range arguments for a cons SEQUENCE if we have good
reason to think they were badly specified.
(Freduce):
Handle multiple values properly. Add bounds checking to this
function, as specificied by ANSI Common Lisp.

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];
