This backend was supposed to generate C++ code which will re-construct the LLVM IR passed as input. This seems to me to have very marginal usefulness in the first place. However, the code has never been updated to use IRBuilder, which makes its current value negative -- people who look at the output may be steered to use the *wrong* C++ APIs to construct IR. Furthermore, it's generated code that doesn't compile since at least 2013. Differential Revision: http://reviews.llvm.org/D19942 llvm-svn: 268631
