  10 |* This header declares the C interface to libLLVMAnalysis.a, which           *|
  11 |* implements various analyses of the LLVM IR.                                *|
  12 |*                                                                            *|
  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.                                           *|
  16 |*                                                                            *|
