# Build tests based on benchmark suites for IREE.
#
# The desired build directory can be passed as the first argument. Otherwise, it
# uses the environment variable IREE_TARGET_BUILD_DIR, defaulting to
# "build-benchmark-suites-test". Designed for CI, but can be run manually. It
# reuses the build directory if it already exists. Expects to be run from the
# root of the IREE repository.
