Hello, I'm from SpB ;) and I'm waiting for Mikhail to appear in Communicator to talk about this. The fact of the matter is that I tried to replace Intrinsic calls with JitHelper calls because at the moment Intrinsics are used only to arraycopy generation. These two "tau" parameters are actually not used (they used only for CharArrayCopy version which is not exist now), and the whole process of arraycopy generation, as it seems to me, is rather easy to create some distinct entities for it. So I made changes in code to eliminate Intrinsics (however there are some places which require particular consideration of Intrinsics, for example, escape analysis), but frequent crashes of vm appeared.
Of course I can make opinion only by reading the code so maybe there are some internal problems which were left unnoticed by me. I hope that the explaining of "tau"s and some internal features will help me to solve the problem. Thank you, Dmitry Pronichkin.
