Make it possible to silence warnings issued when #'mapcar's result is discarded.
lisp/ChangeLog addition:
2009-10-19 Aidan Kehoe <kehoea@parhasard.net>
* bytecomp.el (byte-compile-default-warnings):
Add two new warning types, discarded-consing (basically use of
mapcar instead of mapc where its result is discarded) and
quoted-lambda (use of a lambda expression quoted as data in a
function context).
(byte-compile-warnings): Document the new warnings.
(byte-compile-fset, byte-compile-funarg): Implement the
quoted-lambda warning option.
(byte-compile-mapcar): Renamed to byte-compile-maybe-mapc.
(byte-compile-maybe-mapc, byte-compile-maplist):
Implement the discarded-consing warning option.
Add more functions that should be compiled using
byte-compile-funarg, notably mapvector, mapc-internal,
map-char-table.
* cl-macs.el (mapcar*):
If we know at compile time that there are no CL options being
used, use the mapcar subr, not the byte-coded function.

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];
