Be better about recognising side-effect-free forms, byte-optimize.el.
2011-05-07 Aidan Kehoe <kehoea@parhasard.net>
* byte-optimize.el:
* byte-optimize.el (byte-optimize-form-code-walker):
Call #'byte-optimize-side-effect-free-p on the form, rather than
just checking the plist of the form's car.
* byte-optimize.el (side-effect-free-fns):
Move the CL functions into their alphabetical place in the list.
* byte-optimize.el (function):
* byte-optimize.el (byte-optimize-side-effect-free-p): New.
Function returning non-nil if a funcall has no side-effects, which
handles things like (remove* item list :key 'car) and
(remove-if-not #'integerp list).

This directory contains C header files containing machine-specific definitions. Each file describes a particular machine. The emacs configuration script edits ../config.h to include the appropriate one of these files, and then each emacs source file includes config.h. template.h is a generic template for machine descriptions; it describes the parameters a machine file can specify. General XEmacs Changes ---------------------- 1. Removed all code dealing with VALBITS and XSET*. These are handled differently in XEmacs. 2. Removed all defines of WORDS_BIGENDIAN. Now determined by configure. 3. Put #ifndef PURESIZE around all PURESIZE defines so that it can be overridden at configure time. 4. Removed all defines of NO_ARG_ARRAY. The arg-array hack is not done in XEmacs. (If you want to put it back, use configure -- autoconf has a check for this.) 5. Removed all defines of BITS_PER_INT, BITS_PER_LONG -- now determined by configure. See ../s/README for a list of other changes made to the FSF 19.30 configuration files for XEmacs.
