Good! Your reply shows me that i may not vorry about this.
Then i would ask you about design of your VM architecture. Its better to start from a clean view, that everything in VM could be changed at some point. And changed by programmer using smalltalk, not C or other external tools. I mean, i want a truly flexible system. I want to be able the smalltalk VM to rebuild self from scratch (producing new VM executable) without using C complier/e.t.c. And be able to change any low level primitives in running VM. As example - let programmer to decide, how to tag smallintegers , with 0 or with 1 , and make this as easy as clicking a single button, just by changing a single line of code in single place. This will open a wide range perspective, how programmer can experiment with VM, how he can add or change its core functionality and test it. Another example - suppose we want to run our VM/image on different platform. All we need is a hooks (like special binary format, accessing to kernel function e.t.c), provided by that platform and assembler support from Exupery to generate opcodes suitable for platform CPU. The we generate a small bootstrap executable, which then can be used for loading image in new platform, and providing a bootstrapping mechanism for recompiling a core VM methods contained in your image. So, you can keep any low-level VM code in your image and be able to run it anywhere without dependancy from external tools like C compiler or linker e.t.c.

But Exupery is facing with the fact that most Squeak's internals can't be changed. I have the ability to change what ever I want in Huemul. An example, Bryce suggested 0 tagged SmallInts. I was using 1 tagged, changed that in a week, then Huemul got faster. The fact is that I am really into learning things. I didn't know how to implement 0 tagged int. Thanks to Klaus (a member of this list), I was able to do it. That kind of reaction is more difficult in Squeak. > At some day i thought, why i want to reinvent the wheel, while there's > already a good and working smalltalk implementation with reach set of > projects/features. I completely agree with you on this matters, I will try to make Huemul compatible with most of them. > And i decided to join squeak community, and asking you to do the same. > You can benefit from others works, while doing your part. Believe me, I use Squeak. There is another thing. Huemul is a Linux X86-32 application. Squeak images run without modification on lots of platforms. It would be very difficult to do that with Huemul.

I asked you for advise. Everybody is welcome.
