Implementing Just-In-Time Compilation

[Vladimir Lushnikov]

[I am writing this in the hope of finding an answer - where google
fails, surely Usenet can help?]

Hello,

I am in the planning process for developing a VM (Virtual Machine). I
have been researching various aspects for developing a VM in C++ for a
(semi?-)dynamic language, and am looking at the possibility of
implementing JIT for the VM. How would one go about an implementation?
Is the bytecode translated into native instructions similar to ASM, and
then assembled completely into processor-specific instructions? It
seems so, but are there any pointers available in the right direction
in the form of papers, tutorials and the like?

Regards,
Vladimir Lushnikov

Try

comp.compilers

The people there most likely knows.

I would have to say that if you need to ask these questions perhapse
you should start with a smaller project. What you are talking about
doing takes years of research and a level of understanding of compiler
design and machine architecture that surpasses most expert programmers.

I was hoping that I was wrong and you didn't have to say that...

My plans for starting such a project is to start with either an
interpreter or a very simple virtual machine that can run some basic
Ruby, and work out the next step then. I am currently reading "Virtual
Machine Design and Implementation in C/C++" by Bill Blunden.

Any other reading starter suggestions?

That shouldn't stop you. I remember a time much people were laughing
about a nobody creating his own UNIX-like system for a PC...

You should have a look at java, I'd assume its the VM with the most
experience regarding just-in-time compilation. There are also groups
(or mailing lists) which discuss different aspects of this topic,
I'm fairly sure the java community can help you finding it.

And now - what was your C++ question? ;)

You can join the parrot community. They use C, not C++, but they have a
bunch of work in parsing, VM design and implementation, JIT, and all of
those things.
