// Note: below we are using tear-offs instead of calling methods directly
// to guarantee very specific compilation order:
//
// - compile main, add get:methodM and get:callMethodM to selector set.
// - compile A.callMethodM and add get:createB to selector set.
// - compile A.createB and mark B as allocated.
//
// Class B is not marked as allocated until A.createB is compiled, which means
// that when A.callMethodM is compiled only class A has get:methodM method
// extractor injected.
//
// This test is verifying that optimizing compiler does not treat this method
// extractor as a single target for this.get:methodM call.

// This adds selector 'get:methodM' into the sent selector set and
// marks class A as allocated.

// This adds get:callMethodM to the sent selector set.
