   3 # "When we build software, it's a good idea to have a reliable method
   4 # for getting an executable from it. We want any two reconstructions
   5 # starting from the same source to end up in the same result. That's
   6 # just a basic intellectual premise."

   9 # This software is part of the SBCL system. See the README file for
  10 # more information.
  11 #
  12 # This software is derived from the CMU CL system, which was
  13 # written at Carnegie Mellon University and released into the
  14 # public domain. The software is in the public domain and is
  15 # provided with absolutely no warranty. See the COPYING and CREDITS
  16 # files for more information.

  18 # The value of SBCL_XC_HOST should be a command to invoke the
  19 # cross-compilation Lisp system in such a way that it reads commands
  20 # from standard input, and terminates when it reaches end of file on
  21 # standard input. Some suitable values are:
  22 #   "sbcl"        to use an existing SBCL binary as a cross-compilation host
  23 #   "sbcl --sysinit /dev/null --userinit /dev/null"
  24 #                 to use an existing SBCL binary as a cross-compilation host
  25 #                 even though you have stuff in your initialization files
  26 #                 which makes it behave in such a non-standard way that
  27 #                 it keeps the build from working
  28 #   "sbcl --disable-debugger"
  29 #                 to use an existing SBCL binary as a cross-compilation host
  30 #                 and tell it to handle errors as best it can by itself
  31 #                 (probably by dying with an error code) instead of waiting
  32 #                 endlessly for a programmer to help it out with input
  33 #                 on *DEBUG-IO*
  34 #   "lisp -batch" to use an existing CMU CL binary as a cross-compilation host
  35 #   "lisp -noinit -batch"
  36 #                 to use an existing CMU CL binary as a cross-compilation host
  37 #                 when you have weird things in your .cmucl-init file
  38 #   "openmcl --batch"
  39 #                 to use an OpenMCL binary as a cross-compilation host
  40 #   "clisp"
  41 #                 to use a CLISP binary as a cross-compilation host
  42 #
  43 # FIXME: Make a more sophisticated command line parser, probably
  44 # accepting "sh make.sh --xc-host foolisp" instead of the
  45 # the present "sh make.sh foolisp".
  46 # FIXME: Tweak this script, and the rest of the system, to support
  47 # a second bootstrapping pass in which the cross-compilation host is
  48 # known to be SBCL itself, so that the cross-compiler can do some
  49 # optimizations (especially specializable arrays) that it doesn't
  50 # know how to implement how in a portable way. (Or maybe that wouldn't
  51 # require a second pass, just testing at build-the-cross-compiler time
  52 # whether the cross-compilation host returns suitable values from
  53 # UPGRADED-ARRAY-ELEMENT-TYPE?)
  54 # FIXME: --noprogrammer was deprecated in sbcl-0.7.5, replaced by
  55 # --disable-debugger. We still use the old form here because the
  56 # change was not preannounced, and it would be rude to make our new
  57 # version of SBCL unbootstrappable by immediately prior versions.
  58 # But in a year or so the --noprogrammer here can change to
  59 # --disable-debugger (and the deprecated --noprogrammer support can
  60 # go away completely).

  88 #     SBCL_XC_HOST=<whatever> sh make-host-1.sh
