This change is basically just copying changes that we've used for Apple's clang builds to the script used for building llvmCore. Besides cleaning it up to use xcrun to locate the proper versions of tools, especially for cross compiling, it fixes the build to work with newer versions of clang that honor SDKROOT settings in the environment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172138 91177308-0d34-0410-b5e6-96231b3b80d8

# 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"

|
# shell script named 'configure' in this directory. This script makes a copy...

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

# The fifth parameter is the place where the compiler will be copied once it's
|
|
# built.
|
|

|
|
|
|
# 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"
|
|

|
|
# enabled in the LLVM libs/tools.

|
|
# The eighth parameter is a yes/no that indicates whether this is an optimized

# build.
