I had no time to read in detail your reply to Gordon (I'll go back to it
later), but the similarities are astonishing. I suspect that it is not
just a coincidence that we use a lispy syntax (defmacro anyone?). I'll
like to learn about your project, so if this is possible, would you like
to provide a pointer to some description? (by private e-mail)

Whatever LLVM has, it is there either for the convenience of frontend ->
backend information flux (note that I exclude the reverse direction) or
for the convenience of LLVM itself. Chris et al. are no shy about
improving the interfaces when they perceive a clear gain, so there are
some chances that whatever you find convenient for your internal stuff
today will be not there tomorrow.
