native code

hello all,

i was wondering if there is any possibility in VW 7.x to gather native
microcode from Smalltalk specification...?

thanks in advance

Samar,

To see the byte code, just open a browser, select a method and use the
inspect menu item. If you mean machine code from the JIT, there are some
debugging tools for VM engineers, but I do not know whether they are
available in general.

Re: AW: native code

Thanks Georg for your prompt reply...yes, actually i was looking to
gather machine code from the JIT....

nebody who knows about such "debugging tools" that are available for free???

regards/thanks in advance

The VM implements some secret primitives that will show a disassembly of
the JITed code.

To get access to these secrets you could enroll in the VW Developers
Program:

I forgot to mention:

Yes it is free (gratis, not libre).

Actually they aren't secret anymore. Load OEprogrammingHacks and OEProfiler and you'll find access to all he support that's there, e.g. inspecting a CompiledMethod will now include a translation selection showing native code. But Reinout makes an excellent suggestion. If as a University researcher you enroll in the vw-dev program you'll get access to the VM source code. If you're interested in optmization ask Andres or myself about AOStA, a far-from-complete adaptive optimization framework for VW for which there is some support in the VM.

Enjoy :)

VW 64-bit issue wrt shared varible definitions

In reply to this post by Reinout Heeck

Hello,

I'm trying out VW 7.5 running on Ubuntu 7.04 64-bit AMD.

One issue is it seems like defining shared variables in a namespace
takes an extremely long time.
Any code that defines shared variables, or loading packages out of Store
that has a large number of shared variables,
takes an extremely long time..

Using VW 7.5 with 32-bit windows doesn't seem to have this problem at all.

Has anyone else noticed this issue?

Thanks, Ian

Martin McClure

I haven't noticed that issue, but I just tried out VW 7.5 64-bit
yesterday for an hour or two.

Is 64-bit 7.5 stable for you on Ubuntu? I had trouble keeping it running
-- the VM would exit on parcel loads, use of Store, etc. These were not
repeatable, but I don't think I ever kept the thing running for more
than five minutes at a time.

Regards,
