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