I am away so I cannot look at the code right now, but in the oscog
VMMaker you should still have BytesPerWord implemented as a class
variable (or pool variable?), and this would be a C macro in the
generated code. In the plugin, we use "self bytesPerWord" rather
than a reference to the BytesPerWord class variable (because
BytesPerWord does not exist in the trunk 32/64 bit code generation).
In VMMaker trunk, "self bytesPerWord" is translated to the C macro
"BYTES_PER_WORD". In oscog VMMaker, it is translated to "BytesPerWord"
which also happens to be a C macro. This works on both branches of
If this is not working for you, let me know the specific VMMaker
and FT2Plugin MCZs that you have loaded, and I will try to reproduce
this when I get home (about 8 hours from now).
