Detailed Description

Base class for error info classes.

Do not extend this directly: Extend the ErrorInfo template subclass instead.

convertToErrorCode()

virtual std::error_code llvm::ErrorInfoBase::convertToErrorCode ( ) const

pure virtual

Convert this error to a std::error_code.

This is a temporary crutch to enable interaction with code still using std::error_code. It will be removed in the future.

Implemented in llvm::FileError, llvm::StringError, llvm::ECError, llvm::json::ParseError, llvm::ErrorList, llvm::DWARFDebugNames::SentinelError, llvm::InstrProfError, llvm::orc::SymbolsCouldNotBeRemoved, llvm::orc::rpc::CouldNotNegotiate, llvm::orc::SymbolsNotFound, llvm::orc::rpc::ResponseAbandoned, llvm::orc::FailedToMaterialize, llvm::SymbolRemappingParseError, llvm::coverage::CoverageMapError, llvm::orc::JITSymbolNotFound, llvm::RuntimeDyldError, llvm::orc::DuplicateDefinition, llvm::orc::rpc::ConnectionClosed, llvm::orc::remote::ResourceNotFound< ResourceIdT >, llvm::mca::InstructionError< T >, and llvm::BinaryStreamError.
