Etienne, Some words about your example.
OPEN doesn't rely on any particular object layout, but tries to define functional interface for object access purposes. Open_Managed_Object_Handle is used to access this functionality from the components other than VM Core. In order to eliminate performance degradation in such overhead, OPEN defines: - Functions that JIT-compiled code calls during its execution (So called Helpers in OPEN) for quick access to objects from the managed code, - Java methods that interact with the managed code of Java class libraries (ObjectAccessors) for quick access from Java API They could be even inlined in managed code thus eliminating any modularization influence. So, any reasonable object layout could be used in OPEN compatible VM implementation, including bidirectional one. Thanks, Andrey On 5/29/06, Etienne Gagnon <[EMAIL PROTECTED]> wrote:
Hi Anton, Are you proposing that all Harmony JVMs must abide by the OPEN proposal? If yes, I think that some process has to be put in place to present and discuss each of this proposal's part, and dedicate time to do so. IMO, I don't think that everyone (in the JVM sub-communityof Harmony) can simply read through this proposal and be able to make an enlightened decision about it. I think that each point would gain much from being presented along the motivation behind it. For example, would your OPEN proposal work with a bidirectional object layout, without incurring prohivitive performance costs? [Just asking, I didn't have time to read through all of it...] Of course, this is only an opinion. :-) Etienne
