Added: bootfiles/20b/boot-2010-11-1-cross.lisp Modified: code/exports.lisp compiler/backend.lisp compiler/dump.lisp

Add new slots to the backend to hold the foreign linkage space start and entry size. Not yet used anywhere.

This change needs a cross-compile; use boot-2010-11-1-cross.lisp as the cross-compile script.

compiler/backend.lisp: o Add the two new slots to the backend.

compiler/dump.lisp: o DUMP-DATA-MAYBE-BYTE-SWAPPING needs to handle (unicode) strings o DUMP-DATA-MAYBE-BYTE-SWAPPING should not swap bytes of a string. Genesis will make that happen.

code/exports.lisp: o Export BACKEND-FOREIGN-LINKAGE-SPACE-START and BACKEND-FOREIGN-LINKAGE-ENTRY-SIZE.

bootfiles/20b/boot-2010-11-1-cross.lisp: o Cross-compile script for this change.
