HotSpot C2 compiler has a set of -XX debugging flags for doing binary
search on top-level methods to compile with C2 (or C1 or interpret), and
a similar control over which methods to inline. While I was at Sun I had
a bisect shell script to narrow down failing compilations (and trim the
set of inlined methods).
