# Build LLVM the "Apple way".
# Parameters:
# The first parameter is a space-separated list of the architectures the
# compilers will run on. For instance, "ppc i386". If the current machine
# isn't in the list, it will (effectively) be added.
# FIXME: HOSTS is not used in this script. Use it or Remove it.
HOSTS="$1"
# The second parameter is a space-separated list of the architectures the
# compilers will generate code for. If the current machine isn't in the list, a
# compiler for it will get built anyway, but won't be installed.
TARGETS="$2"
# The third parameter is the path to the compiler sources. There should be a
# shell script named 'configure' in this directory. This script makes a copy...
ORIG_SRC_DIR="$3"
# The fourth parameter is the location where the LLVM will be installed. You can
# move it once it's built, so this mostly controls the layout of $DEST_DIR.
DEST_ROOT="$4"
# The fifth parameter is the place where the compiler will be copied once it's
# built.
DEST_DIR="$5"
# The sixth parameter is a directory in which to place information (like
# unstripped executables and generated source files) helpful in debugging the
# resulting compiler.
SYM_DIR="$6"
# The seventh parameter is a yes/no that indicates whether assertions should be
# enabled in the LLVM libs/tools.
LLVM_ASSERTIONS="$7"
# The eighth parameter is a yes/no that indicates whether this is an optimized
# build.
LLVM_OPTIMIZED="$8"
# The nineth parameter is the version number of the submission, e.g. 1007.
LLVM_SUBMIT_VERSION="$9"
# The tenth parameter is the subversion number of the submission, e.g. 03.
LLVM_SUBMIT_SUBVERSION="${10}"
# The current working directory is where the build will happen. It may already
# contain a partial result of an interrupted build, in which case this script
# will continue where it left off.
