[pypy-dev] llvm2 update

[Richard Emslie]

Hi all,

I've just added a dummy OpaqueType implementation and refactored the 
database wrt to pbc nodes.  So pbcs are working for classes too now.

Here is a brief overview of things that (I think) still need to me done.

todo (probably in this order):

* exception flow of control

* any missing operations implementations (bit shifting for instance).
   These can be added when they are needed and should be straight forward.

* review and update external function implementations for new way of doing
   things

* overflows on ints/etc (more on that from Carl Friedrich...)


refactoring:

* should is_atomic() be a method?

* grep "XXX"s :-)


Of the above I am guess that exceptions are most interesting.  The unwind 
/ invoke operations of llvm fits this quite well, but still need somewhere 
to store the exception and do matching - unless I missed something?  Any 
thoughts / takers?

Cheers,
Richard
