that is cool, so the other thing i was thinking about is that MMTK is written for JikesRVM which is a meta-circular java implementation. AKA it is written in java with some magic for the low level mem stuff. I am not sure how that would integrate into Harmoney and the DRLVM. I dont think it would be hard to port it to another language or we could write some sort of interface to bridge the two. Not sure what are your ideas?
hmm.... somewhere I heard that MMTK had been ported to Microsoft Rotor. I know Rotor is a vm written in C/C++. If this port is under an Apache agreeable license, then we could look at this code. If no MMTK-to-C interface that is compatible with Apache license exists then, of course, we will need to build one. My preference would be to keep it the interface combinations to C and Java. I would rather not bog down MMTK/HarmonyDRLVM with any C++ distractions initially. I think the initial focus is functionality, cleaning up the C interface, then performance.
