Compiling Object.<init>

[Gary Benson]

Hi all,

I'm writing a JIT for OpenJDK, and I'm not sure what I should be doing
when compiling Object.<init>.  I was confused to see it scheduled for
compilation at all, since it's an empty method, but now I see its one
bytecode is not _return but _return_register_finalizer so of course
the empty method detector doesn't recognise it.

When it gets compiled, the bytecode is read via a ciBytecodeStream,
and it seems to be coming through as a _return as I have no code to
handle _return_register_finalizer and it would have aborted if it got
that.

Do I need to detect that I'm compiling Object.<init> and special case
it?

Cheers,
Gary
