llvm dev - Jun 2014 - [LLVMdev] A question about running Clang after LLVM passes

Hello,


Clang is used before LLVM to generate IR, and is it possible to use it in a
reverse way, i.e., after running LLVM passes, we can run clang again to use LLVM
pass results? If so, should I write clang functions in LLVM passes, or write
LLVM pass requirements in clang?


Thank you in advance!

Clang does not consume LLVM IR, so the answer is no. What are you trying to
do?

However, LLVM can output using the C back end ... which you can then feed
into Clang.
