[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.

Hi;
I am writing a class that implements IDbConnection. The i/f defines a method
BeginTransaction() that returns an IDbTransaction. I want to define this as
returning a DbTransaction (as DbConnection does). It makes sense to me that
this is legal as DbTransaction implements IDbTransaction so it does meet the
contract of returning an IDbTransaction.
But it won't compile - how do I get this to work? There must be a way as

Since implement the assign operator for reference types eliminates the
ability to assign a reference object to a reference variable of the same
type or base class of that type, I assume that implementing the assign
operator ( = ), to assign the value of a type from one object to another
rather than the reference, should only be done for value types. Is there
any other reason for implementing the assign operator for a type ?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
