;;;; This software is derived from the CMU CL system, which was

;;; a linear ordering of system sources which works both to
;;; compile/load the cross-compiler under the host Common Lisp and
;;; then to cross-compile the complete system into the
;;; under-construction target SBCL
;;;
;;; The keyword flags (:NOT-HOST, :NOT-TARGET, :ASSEM...) are
;;; documented in the code which implements their effects. (As of
;;; sbcl-0.7.10, the comments are on DEFPARAMETER *EXPECTED-STEM-FLAGS*
;;; in src/cold/shared.lisp.)
;;;
;;; Of course, it'd be very nice to have this be a dependency DAG
;;; instead, so that we could do automated incremental recompilation.
;;; But the dependencies are varied and subtle, and it'd be extremely
;;; difficult to extract them automatically, and it'd be extremely
;;; tedious and error-prone to extract them manually, so we don't
;;; extract them. (It would be nice to fix this someday. The most
;;; feasible approach that I can think of would be to make the
;;; dependencies work on a package level, not an individual file
;;; level. Doing it at the package level would make the granularity
;;; coarse enough that it would probably be pretty easy to maintain
;;; the dependency information manually, and the brittleness of the
;;; package system would help make most violations of the declared
;;; dependencies obvious at build time. -- WHN 20000803

 ;; becase IN-TARGET-CROSS-COMPILATION-MODE assigns the reader macros before
 ;; compiling anything. It is, however, a minor concern for make-host-1, but
 ;; usually a problem can be exposed only by contrived code / poor style.
 ;; e.g. if the host's reader were used when compiling
 ;;  (EVAL-WHEN (#-SB-XC :COMPILE-TOPLEVEL :LOAD-TOPLEVEL :EXECUTE)
 ;;    (DEFUN A-MACRO-HELPER () '`(FOO ,A ,B))
 ;; then A-MACRO-HELPER returns host code, and calling it might be wrong, either
 ;; obviously or subtly. If the result is (LIST* 'FOO (LIST* A (LIST B)))
 ;; then it's subtly wrong because it might not be the optimal strategy;
 ;; whereas if it's (BACKQUOTE (FOO (UNQUOTE A) (UNQUOTE B))) then it's
 ;; flat out wrong. At any rate, judicious avoidance of EVAL-WHEN and nested
 ;; quasiquotation in 'primordial-extensions' prevents any such issues.
