;;;; Generate stubs for C-linkage library functions which we need to refer to
;;;; from Lisp.
;;;;
;;;; (But note this is only the Linux version, as per the FIXME
;;;; note in the BSD version in undefineds.h.)
;;;;
;;;; These stubs exist for the benefit of Lisp code that needs to refer
;;;; to foreign symbols when dlsym() is not available (i.e. when dumping
;;;; cold-sbcl.core, when we may be running in a host that's not SBCL,
;;;; or on platforms that don't have it at all). If the runtime is
;;;; dynamically linked, library functions won't be linked into it, so
;;;; the map file won't show them. So, we need a bunch of stubs that
;;;; nm(1) _can_ see.
;;;;
;;;; This software is part of the SBCL system. See the README file for
;;;; more information.
;;;;
;;;; This software is derived from the CMU CL system, which was
;;;; written at Carnegie Mellon University and released into the
;;;; public domain. The software is in the public domain and is
;;;; provided with absolutely no warranty. See the COPYING and CREDITS
;;;; files for more information.
