Co-operate with the byte-optimizer in the bytecomp.el labels implementation. lisp/ChangeLog addition: 2012-05-05 Aidan Kehoe <kehoea@parhasard.net> Co-operate with the byte-optimizer in the bytecomp.el labels implementation, don't work against it. * byte-optimize.el: * byte-optimize.el (byte-compile-inline-expand): Call #'byte-compile-unfold-lambda explicitly here, don't assume that the byte-optimizer will do it. * byte-optimize.el (byte-compile-unfold-lambda): Call #'byte-optimize-body on the body, don't just mapcar #'byte-optimize-form along it. * byte-optimize.el (byte-optimize-lambda): New. Optimize a lambda form. * byte-optimize.el (byte-optimize-form-code-walker): Descend lambda expressions, defun, and defmacro, relevant for lexically-oriented operators like #'labels. * byte-optimize.el (byte-optimize-body): Only return a non-eq object if we've actually optimized something * bytecomp.el (byte-compile-initial-macro-environment): In the labels implementation, work with the byte optimizer, not against it; warn when labels are defined but not used, automatically inline labels that are used only once. * bytecomp.el (byte-recompile-directory): No need to wrap #'byte-compile-report-error in a lambda with #'call-with-condition-handler here. * bytecomp.el (byte-compile-form): Don't inline compiled-function objects, they're probably labels. * bytecomp.el (byte-compile-funcall): No longer inline lambdas, trust the byte optimizer to have done it properly, even for labels. * cl-extra.el (cl-macroexpand-all): Treat labels established by the byte compiler distinctly from those established by cl-macs.el. * cl-macs.el (cl-do-proclaim): Treat labels established by the byte compiler distinctly from those established by cl-macs.el. * gui.el (make-gui-button): When referring to the #'gui-button-action label, quote it using function, otherwise there's a warning from the byte compiler.
