|* This header declares the C interface to libLLVMScalarOpts.a, which         *|
|* implements various scalar transformations of the LLVM IR.                  *|
|*                                                                            *|
|* Many exotic languages can interoperate with C code but have a harder time  *|
|* with C++ due to name mangling. So in addition to C, this interface enables *|
|* tools written in such languages.                                           *|
