Mattias Engdegård 7acb3f1c06 Add the function declaration and property important-return-value ... Now the declaration (declare (important-return-value t)) can be used to have the byte-compiler warn when the return value from a call is discarded (bug#61730). * lisp/emacs-lisp/bytecomp.el (byte-compile-form) (important-return-value-fns): Use the function property `important-return-value` instead of looking through a static list. * lisp/emacs-lisp/byte-run.el (byte-run--set-important-return-value) (defun-declarations-alist): New function declaration, setting the property of the same name. * lisp/emacs-lisp/cl-macs.el: * lisp/subr.el (assoc-default): Set the property. * doc/lispref/functions.texi (Declare Form): * doc/lispref/symbols.texi (Standard Properties): Document. * etc/NEWS: Announce.		2023-05-01 17:11:50 +02:00
