Today I see several possible solutions. The complete solution with calling arbitrary native methods from Java is not ready: we are just discussing it in a separate thread. The first step of calling arbitrary native calls from Java is VM helpers inlining framework. I'm going to commit it today and will notify you about JIRA num. I hope it will serve as example.
The solutions we have today: 1) If you have only a few methods to be affected: create separate JIT instance without inliner and add method filters to EM configuration file. Check http://incubator.apache.org/harmony/subcomponents/drlvm/emguide.htmland *.emconf files for details. 2) If you need to avoid inlining of special method in all Java methods you can use 'skip_methods' parameter of inliner pass. See opt.emconf file to check how to pass parameters to inliner. 3) Replace all calls to your method with VMHelperCall in translator. Process it as direct calls in codegenerator. This solution was already proposed by Egor. -- Mikhail Fursov
