Description

Resolve linkage for prevailing symbols in the \p Index. Linkage changes recorded in the index and the ThinLTO backends must apply the changes to the module via thinLTOResolvePrevailingInModule. This is done for correctness (if value exported, ensure we always emit a copy), and compile-time optimization (allow drop of duplicates).

function_ref<bool( GlobalValue::GUID, const llvm::GlobalValueSummary*)> isPrevailing

function_ref<void(llvm::StringRef, GlobalValue::GUID, GlobalValue::LinkageTypes)> recordNewLinkage
