| |* This header declares the C interface to the Target and TargetMachine       *|
 | |
| |* classes, which can be used to generate assembly or object files.           *|
 | |
| |*                                                                            *|
 | |
| |* 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.                                           *|
