If you have your code at the AST level, you might as well use CLANG to
work at the AST level and create C code as output.
CLANG is closely linked to LLVM.
There seems very little point in lowering the AST to LLVM-IR then
output to C. You will loose useful structural information.
E.g. By using something like this with CLANG would be better:

Also, if you can create AST in a format CLANG understands, it can then
automatically lower it to LLVM-IR, and you will have your completed
compiler for your own language.

The mailing list for CLANG is
