This is a script to build ISPC from scratch, including building patched version of LLVM.
NOTE THAT RELEASE VERSION OF ISPC MUST BE BUILT WITH PATCHED VERSION OF LLVM.
Options:
-v, --version LLVM version to build with. ${llvm_version} is currently recommended.
-h, --ispc_home Path to ISPC HOME directory.
-l, --llvm_dir Path to use for LLVM build. ${llvm_dir} is default.
-b, --ispc_build Path to ISPC build directory. ${ispc_build} is default.
-i, --ispc_install Path to ISPC install directory. ${ispc_install} is default.
-j, --speed Number of threads for build. ${speed} is default.
--help Display this help and exit.
