# This script helps you run one or all tests in the LLVM test-suite
# It automatically detects the CPU, the number of cores and uses
# command line options to set up debug or special builds.
#
# The script assumes the install directory is at ../install. It's handy to
# have a symlink to whatever directory you're building to, either a build
# directory or a release/rc1/Phase3/.../*.install
