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).

/* How this works:

 Fdump_emacs dumps everything up to my_edata as text space (pure).

 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.
