LLVM cpp backend, does it replace c backend?

My question is regarding the CPP backend, does it serve the same purposes as the C backend? The C backend was one of my favorite LLVM features, and I'm very upset it was removed.

Whats the real differences? I' most appreciative of any help.

Reference: The LLVM 3.1 Release Notes "The C backend has been removed ..."

The CPP backend creates LLVM API calls to create an AST that represent the equivalent of the LLVM assembly. You can try the CPP backend at http://llvm.org/demo/ by selecting the "LLVM C++ API code" Target.

The C backend creates C code that execute the semantics of the LLVM assembly.

They are fundamentally different.
