LLVM cpp backend, does it replace c backend?

问题

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 ..."

回答1:

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.
