   5 # for getting an executable from it. We want any two reconstructions
   6 # starting from the same source to end up in the same result. That's
   7 # just a basic intellectual premise."

  11 # more information.

  13 # This software is derived from the CMU CL system, which was
  14 # written at Carnegie Mellon University and released into the
  15 # public domain. The software is in the public domain and is
  16 # provided with absolutely no warranty. See the COPYING and CREDITS
  17 # files for more information.

  19 # The value of SBCL_XC_HOST should be a command to invoke the
  20 # cross-compilation Lisp system in such a way that it reads commands
  21 # from standard input, and terminates when it reaches end of file on
  22 # standard input. Some suitable values are:
  23 #   "sbcl"        to use an existing SBCL binary as a cross-compilation host
  24 #   "sbcl --sysinit /dev/null --userinit /dev/null"
  25 #                 to use an existing SBCL binary as a cross-compilation host
  26 #                 even though you have stuff in your initialization files
  27 #                 which makes it behave in such a non-standard way that
  28 #                 it keeps the build from working
  29 #   "sbcl --disable-debugger"
  30 #                 to use an existing SBCL binary as a cross-compilation host
  31 #                 and tell it to handle errors as best it can by itself
  32 #                 (probably by dying with an error code) instead of waiting
  33 #                 endlessly for a programmer to help it out with input
  34 #                 on *DEBUG-IO*
  35 #   "lisp -batch" to use an existing CMU CL binary as a cross-compilation host
  36 #   "lisp -noinit -batch"
  37 #                 to use an existing CMU CL binary as a cross-compilation host
  38 #                 when you have weird things in your .cmucl-init file
  39 #   "openmcl --batch"
  40 #                 to use an OpenMCL binary as a cross-compilation host
  41 #   "clisp"
  42 #                 to use a CLISP binary as a cross-compilation host
  43 #
  44 # FIXME: Make a more sophisticated command line parser, probably
  45 # accepting "sh make.sh --xc-host foolisp" instead of the
  46 # the present "sh make.sh foolisp".
  47 # FIXME: Tweak this script, and the rest of the system, to support
  48 # a second bootstrapping pass in which the cross-compilation host is
  49 # known to be SBCL itself, so that the cross-compiler can do some
  50 # optimizations (especially specializable arrays) that it doesn't
  51 # know how to implement how in a portable way. (Or maybe that wouldn't
  52 # require a second pass, just testing at build-the-cross-compiler time
  53 # whether the cross-compilation host returns suitable values from
  54 # UPGRADED-ARRAY-ELEMENT-TYPE?)

  90 #   Create copies of the source tree on both the host and the target.

 100 #   Copy src/runtime/sbcl.nm and output/stuff-groveled-from-headers.lisp

 103 #     SBCL_XC_HOST=<whatever> sh make-host-2.sh
