}示例2: getModRefInfo
ModRefInfo SwiftAAResult::getModRefInfo(llvm::ImmutableCallSite CS,
const llvm::MemoryLocation &Loc) {
// We know at compile time that certain entry points do not modify any
// compiler-visible state ever. Quickly check if we have one of those

getConservativeModRefForKind(*CS.getInstruction()))
return ModRefInfo::NoModRef;
// Otherwise, delegate to the rest of the AA ModRefInfo machinery.
