Hi Bill:

Would it be easier to convert from LLVM's bytecode to C as opposed to
from RTL?  What about the readability of the produced C code.  I would
think since RTL maintains a structure that is directly inherited from
the high-level language structure it would be less difficult to turn it
into some C code that is relatively more readable, as compared to
synthesizing C code from the low-level bytecode.  I stand corrected.
