      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 HOSTS="$1"

     14 # The second parameter is a space-separated list of the architectures the
     15 # compilers will generate code for. If the current machine isn't in the list, a
     16 # compiler for it will get built anyway, but won't be installed.

     21 # shell script named 'configure' in this directory. This script makes a copy...
     22 ORIG_SRC_DIR="$3"
     23 
     24 # The fourth parameter is the location where the LLVM will be installed. You can
     25 # move it once it's built, so this mostly controls the layout of $DEST_DIR.
     26 DEST_ROOT="$4"

     29 # built.

     31

     34 # resulting compiler.
     35 SYM_DIR="$6"
