[Vm-dev] How to convert a Byte to an integer in VMMaker

[Klaus D. Witzel]

Hi Math,

IIRC #positive32BitIntegerFor: returns a boxed instance of  
LargePositiveInteger and it looks like that is not what you want to pass  
to #sufficientSpaceToInstantiate: and to #instantiateClass:

I suggest to have a look at the implementor of #experimentalBytecode, that  
one reads bytes from the current IP and makes use of them.
