00010 |* This header declares the C interface to libLLVMBitReader.a, which          *|
00011 |* implements input of the LLVM bitcode format.                               *|
00012 |*                                                                            *|
00013 |* Many exotic languages can interoperate with C code but have a harder time  *|
00014 |* with C++ due to name mangling. So in addition to C, this interface enables *|
00015 |* tools written in such languages.                                           *|
00016 |*                                                                            *|
