getSyntheticSymbolDependencies()

virtual SyntheticSymbolDependenciesMap llvm::orc::ObjectLinkingLayer::Plugin::getSyntheticSymbolDependencies ( MaterializationResponsibility &  MR )

inlinevirtual

Return any dependencies that synthetic symbols (e.g.

init symbols) have on symbols in the LinkGraph. This is used by the ObjectLinkingLayer to update the dependencies for the synthetic symbols.
