enum CompilationResult {
// We tried to compile the code, but we couldn't compile it. This could be
// because we ran out of memory, or because the compiler encountered an
// internal error and decided to bail out gracefully. Either way, this implies
// that we shouldn't try to compile this code block again.
CompilationFailed,
// The profiling assumptions that were fed into the compiler were invalidated
// even before we finished compiling. This means we should try again: in such
// cases the profiling will now be updated and the next compilation won't
// encounter the same problem. But it does mean that we should exercise
// exponential back-off, to get even more profiling so that new profiling
// pathologies aren't encountered.
CompilationInvalidated,
// The compilation succeeded and the code block now has JITCode for the newly
// compiled code. However, compilation success doesn't mean that the CodeBlock
// will execute yet; you typically have to install it first, unless you plan
// on invoking it manually (something that *could* be done for some kinds of
// OSR entry).
CompilationSuccessful,
// We decided to do the compilation asynchronously. This means that we haven't
// yet compiled the code. This only happens when you pass a
// DeferredCompilationCallback. That callback will get called with some
// interesting result, once compilation completes.
