Any LLVM experts on the list?
If it just need to use the C++ API, we can compile a bridge c++ file
to export the missing C++ API to C file. It is actually pretty common praticse
if you play with LLVM internal a lot, some API just don't exist in C yet.
We are already using g++ to link llvm, one more c++ file could not hurt.
If we need some C++ only API later, we can add it there as well.
What do you say?
LLVM 3.0 is going to be released "real soon now" so I don't think it's
a problem in practice. We'd need to add a version check, though so we
don't break build on machines that have older LLVM installed.
Still, it will take a while for the distribution to update to the new version.
Pulling in bits of LLVM itself into sparse, to make older versions work,
seems like a mess of work and maintenance without a driving need. Just
note that 3.0 is required, and things will sort themselves out in time.
