llvm-6502/utils/buildit/build_llvm
Bob Wilson 585d580acb When building llvmCore, pass the SDKROOT and -arch setting to configure. 
So far all of configure tests have been run against the default SDK and
architecture, regardless of what is actually being built.  We've gotten
lucky until now.  <rdar://problem/11112479>

# 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.
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.
# FIXME: The list of targets is currently hard-coded and TARGETS is not used.
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 ninth parameter is a yes/no that indicates whether libLTO.dylib
# should be installed.
INSTALL_LIBLTO="$9"
# A yes/no parameter that controls whether to cross-build for an ARM host.
ARM_HOSTED_BUILD="${10}"
# A yes/no parameter that controls whether to cross-build for the iOS simulator
IOS_SIM_BUILD="${11}"
# The version number of the submission, e.g. 1007.
LLVM_SUBMIT_VERSION="${12}"
# The subversion number of the submission, e.g. 03.

# contain a partial result of an interrupted build, in which case this script
