I'm gradually finding more pieces of the puzzle:

1) there is a wrapper to LLVM's ExecutionEngine.ParseAssemblyString
2) there are calls to ee.parse in pyllvm/test/test_ee.py, but only with test snippets

but then:

3) there is code for generating llva in codewriter.py
4) calls to codewriter come from *node.py modules, these stitch together the pypy
flow and type objects into llva code
5) genllvm.py coordinates all of this and then calls to buildllvm 

It seems that steps 1 and 2 are yet to be used as buildllvm uses the commandline
llvm-as at the moment.
