Here’s a bash script to automatically check out and build the latest LLVM/Clang sources in Release mode:

#!/bin/bash 
CURDIR=$(pwd)/
LLVMDIR=${CURDIR}/llvm
CLANGDIR=${LLVMDIR}/tools/clang
BUILDDIR=${CURDIR}/build

mkdir ${BUILDDIR}

if [ ! -d ${LLVMDIR} ]
then
 mkdir ${LLVMDIR}
fi

cd ${LLVMDIR}
if [ ! -d .svn ]
then
 echo Checking out LLVM source
 svn co http://llvm.org/svn/llvm-project/llvm/trunk .
else
 echo Updating LLVM source
 svn update
fi

if [ ! -d ${CLANGDIR} ]
then
 mkdir ${CLANGDIR}
fi

cd ${CLANGDIR}
if [ ! -d .svn ]
then
 echo Checking out Clang source
 svn co http://llvm.org/svn/llvm-project/cfe/trunk .
else
 echo Updating Clang source
 svn update
fi

if [ ! -d ${BUILDDIR} ]
then
 mkdir ${BUILDDIR}
fi

cd ${BUILDDIR}
${LLVMDIR}/configure
