Improve for-effect handling in a few places, lisp/ lisp/ChangeLog addition: 2012-05-01 Aidan Kehoe <kehoea@parhasard.net> * byte-optimize.el (byte-optimize-form-code-walker): * byte-optimize.el (byte-optimize-or): Improve handling of for-effect here; we don't need to worry about discarding multiple values when for-effect is non-nil, this applies to both #'prog1 and #'or. * bytecomp.el (progn): * bytecomp.el (byte-compile-file-form-progn): New. Put back this function, since it's for-effect there's no need to worry about passing back multiple values. * cl-macs.el (cl-pop2): * cl-macs.el (cl-do-pop): * cl-macs.el (remf): * cl.el (pop): Expand to (prog1 (car-safe PLACE) (setq PLACE (cdr PLACE))) in all these macros, since that optimizes better (especially for-effect handling) when byte-compile-delete-errors is nil.
