Lang Hames 6d32002e2b [ORC] Add utilities to RTDyldObjectLinkingLayer2 to simplify symbol flag ... management and materialization responsibility registration. The setOverrideObjectFlagsWithResponsibilityFlags method instructs RTDyldObjectlinkingLayer2 to override the symbol flags produced by RuntimeDyld with the flags provided by the MaterializationResponsibility instance. This can be used to enable symbol visibility (hidden/exported) for COFF object files, which do not currently support the SF_Exported flag. The setAutoClaimResponsibilityForObjectSymbols method instructs RTDyldObjectLinkingLayer2 to claim responsibility for any symbols provided by a given object file that were not already in the MaterializationResponsibility instance. Setting this flag allows higher-level program representations (e.g. LLVM IR) to be added based on only a subset of the symbols they provide, without having to write intervening layers to scan and add the additional symbols. This trades diagnostic quality for convenience however: If all symbols are enumerated up-front then clashes can be detected and reported early. If this option is set, clashes for the additional symbols may not be detected until late, and detection may depend on the flow of control through JIT'd code. llvm-svn: 341154		2018-08-31 00:53:17 +00:00
