btw, in case it's not clear how to use it then do the following:
a) untar the files into php5/Zend
b) Apply zend_vm_gen.diff (this is a one time thingy which will be resolved
if the patch is applied).
c) Run php zend_vm_gen.php --help
There'll be some files which can be deleted later on if we use this method.

Subject: New VM ArchitectureDue to popular demand, attached is an example of how the new VM
architecture would be without the macro magic.
Basically, the zend_vm_gen.php script auto-generates the chosen VM
architecture (goto/call/switch) and the user can also select if he wants
to specialize opcodes and/or wants the generator to enable/disable
preprocessor #line statements (for debugging it might be easier to not
produce them so that you get to debug the actual code without macros).It's not attached this time due to our annoying attachment filter :)

Please play around with it and send me feedback. We should pretty much
decide what's preferred. The preprocessor stuff or this script. I think I
favor the script even though the script itself has to be maintained,
mainly because I think the preprocessor stuff was kind of hard to
understand and mainly to debug. The auto-generated code will definitely be
easier to debug as it won't have as many macros.Andi
