   9 # The first parameter is a space-separated list of the architectures the
  10 # compilers will run on. For instance, "ppc i386". If the current machine
  11 # isn't in the list, it will (effectively) be added.
  12 # FIXME: HOSTS is not used in this script. Use it or Remove it.
  13 HOSTS="$1"
  14
  15 # The second parameter is a space-separated list of the architectures the
  16 # compilers will generate code for. If the current machine isn't in the list, a
  17 # compiler for it will get built anyway, but won't be installed.
  18 TARGETS="$2"

  20 # The third parameter is the path to the compiler sources. There should be a
  21 # shell script named 'configure' in this directory. This script makes a copy...

  25 # move it once it's built, so this mostly controls the layout of $DEST_DIR.

  28 # The fifth parameter is the place where the compiler will be copied once it's
  29 # built.
  30 DEST_DIR="$5"

  32 # The sixth parameter is a directory in which to place information (like
  33 # unstripped executables and generated source files) helpful in debugging the
  34 # resulting compiler.
  35 SYM_DIR="$6"
  36
  37 # The seventh parameter is a yes/no that indicates whether assertions should be
  38 # enabled in the LLVM libs/tools.

  42 # build.
