|* This header declares the C interface to libLLVMOrcJIT.a, which implements *|
|
|
|* JIT compilation of 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. *|
|
|
|* *|
|
|
|* Note: This interface is experimental. It is *NOT* stable, and may be *|
|
|
|* changed without warning. *|
