Hi,
Please pull.
I broke some of the most recent changes to mainline (stack-trace printing),
that I will hopefully get around to fixing soon. For now, I really think
you should pull, simply because I am not able to keep up with tgrabiec and
ahuillet's patches anymore. And almost everything they do requires me to
change their code afterwards, requiring twice the amount of work.
'make test' and 'make regression' still pass, but both the build and the run-
time output has become quite a bit noisier.
I didn't remove jamvm/ or lib/ yet -- we don't really need to do it yet. That
code is not even being compiled for now. I will remove that soon. (So even
though 7.5k lines added looks like a lot, the full jamvm/ is more than 16.5k
in just .c files).
Things to note, code-wise:
* struct classblock is now struct vm_class, and all vm_class "methods", i.e.
functions that take a vm_class as the first argument and operates on it
can be found in include/vm/class.h and vm/class.c and are prefixed with
"vm_class_". Also, most functions that deal with classes should now pass
struct vm_class * around directly, instead of passing struct object * and
doing CB_CLASS() on the struct object *.
* struct methodblock is now struct vm_method. All vm_method "methods" can be
found in include/vm/method.h and vm/method.c and have the prefix
"vm_method_".
* struct object is now struct vm_object. All vm_object "methods/constructors"
are found in include/vm/object.h and vm/object.c and have the prefix
"vm_object_".
Ok. Please review and pull if this looks okay.
