// |jit-test| skip-if: !wasmGcEnabled()

// Attempt to test intercalls from ion to baseline and back.
//
// We get into this situation when the modules are compiled with different
// tiering policies, or one tiers up before the other, or (for now) one opts
// into gc and is baseline-compiled and the other does not and is ion-compiled.
// There are lots of variables here.  Generally, a small module will be
// ion-compiled unless there's reason to baseline-compile it, so we're likely
// actually testing something here.
//
// Some logging with printf confirms that refmod is baseline-compiled and
// nonrefmod is ion-compiled at present, with --wasm-gc enabled.
