// Bug 2043040 - Crash [@ FunctionCompiler::emitInlineCall] with JSPI synchronous
// tier-up on continuation stack. GenerateRequestTierUpStub must switch to the main
// stack before calling into C++, so Ion compilation doesn't run on the small
// continuation stack.

// Build a chain of 64 small inlinable functions.
