The right thing to do is clear: convert the Java front end to use trees
that are more like the C/C++ trees. (C++ is C plus some C++-specific
extensions; I expect you want C plus some Java-specific extensions.)
Then, use the existing inliner.
Anything else leads to greater incompatibility between the front ends,
and, as such, constitutes a step in distinctly the wrong direction.
This really should not be hard; the Java source language looks very
much like the C/C++ source language. The control-flow constructs are
very similar.
I know that some of the Java developers think that the Java front end's
representation is superior. That's a fine opinion to have, and maybe
switching the C/C++ front end to the Java representation is OK too -- but
that's a lot more work. The Java representation certainly isn't
sufficiently more superior to justify that.
