Hello, this is legacy thread structure. You're right, there was no HyThread at first, but VM_thread structure. Also different DRLVM modules used to have dedicated fields in this structure. Further it was decided to make threading module independent and make usage model of threading module the same for all other modules(i.e use thread local storage for module specific data). But since VM_thread structure usage was very heavy it was also decided to leave all non threading data in VM_thread and put it in TLS till better times (I mean, till this data will be divided into module depended parts and also put into TLS under different keys).

Hi all, I'm now reading the lastest version of drlvm. Now I have a question about the thread management module. I see that there are three kinds of control blocks: HyThread, JVMTIThread and VM_thread. What's the difference of their rols? Especially HyThread and VM_thread. As far as I know, there is no HyThread at first. Thanks, Fan Bin
