# Top-level test runner. Usage is "run.sh" to run tests in compile-only mode,
# or "run.sh <runwasi>" where <runwasi> is a WASI-capable runtime to run the
# tests in full compile and execute mode.
#
# By default this script will look for `clang` and `clang++` in $PATH and
# assume that they are correctly configured with the sysroot in the default
# location.  Alternatively, exporting $CC and $CXX allow more flexibility. e.g:
#
#  export CXX="<wasi-sdk>/bin/clang++ --sysroot <wasi-sdk>/share/wasi-sysroot"
#  export CCC="<wasi-sdk>/bin/clang --sysroot <wasi-sdk>/share/wasi-sysroot"
#

# Determine the wasm runtime to use, if one is provided.
