Be better about eliminating `block's that are not `return-from'd, bytecomp.el 2011-02-12 Aidan Kehoe <kehoea@parhasard.net> * bytecomp.el: * bytecomp.el (byte-compile-initial-macro-environment): * bytecomp.el (unwind-protect): * bytecomp.el (byte-compile-active-blocks): * bytecomp.el (byte-compile-catch): * bytecomp.el ('return-from-1): Removed. * bytecomp.el ('block-1): Removed. * bytecomp.el (byte-compile-block-1): Removed. * bytecomp.el (byte-compile-return-from-1): Removed. * bytecomp.el (byte-compile-throw): * cl-macs.el (block): * cl-macs.el (return-from): In my last change, the elimination of `block's that were never `return-from'd didn't work if `cl-macroexpand-all' was called explicitly, something much code in cl-macs.el does. Change the implementation to something that doesn't require shadowing of the macros in `byte-compile-initial-macro-environment', putting a `cl-block-name' property on the gensym'd symbol argument to `catch' instead.
