discard()

void llvm::orc::SimpleMachOHeaderMU::discard ( const JITDylib &  JD, const SymbolStringPtr &  Name  )

overridevirtual

Implementations of this method should discard the given symbol from the source (e.g.

if the source is an LLVM IR Module and the symbol is a function, delete the function body or mark it available externally).

Implements llvm::orc::MaterializationUnit.
