class MemoryUse
Declaration
class MemoryUse : public MemoryUseOrDef { /* full declaration omitted */ };Description
Represents read-only accesses to memory In particular, the set of Instructions that will be represented by MemoryUse's is exactly the set of Instructions for which AliasAnalysis::getModRefInfo returns "Ref".

llvm::MemoryAccess* getOptimized() constDeclared at: llvm/include/llvm/Analysis/MemorySSA.h:356
¶bool isOptimized() const
bool isOptimized() constDescription
Whether the MemoryUse is optimized. If ensureOptimizedUses() was called, uses will usually be optimized, but this is not guaranteed (e.g. due to invalidation and optimization limits.)
