MachineBasicBlock MachineBasicBlock::iterator DebugLoc DL

Expand Atomic instructions

A parsed version of the target data layout string in and methods for querying it.

An instruction for reading from memory.

PreservedAnalyses run(Function &F, FunctionAnalysisManager &AM)

Definition MemDerefPrinter.cpp:18

A set of analyses that are preserved following a run of a transformation pass.

static PreservedAnalyses all()

Construct a special preserved set that preserves all passes.

size_type count(ConstPtrType Ptr) const

count - Return 1 if the specified pointer is in the set, 0 otherwise.

std::pair< iterator, bool > insert(PtrType Ptr)

Inserts Ptr if and only if there is no element in the container equal to Ptr.

SmallPtrSet - This class implements a set which is optimized for holding SmallSize or less elements.

void push_back(const T &Elt)

This is a 'vector' (really, a variable-sized array), optimized for the case when the array is small.

LLVM Value Representation.

Type * getType() const

All values are typed, get the type of this value.

This is an optimization pass for GlobalISel generic memory operations.

decltype(auto) dyn_cast(const From &Val)

dyn_cast - Return the argument parameter cast to the specified type.

LLVM_ABI bool isDereferenceableAndAlignedPointer(const Value *V, Type *Ty, Align Alignment, const DataLayout &DL, const Instruction *CtxI=nullptr, AssumptionCache *AC=nullptr, const DominatorTree *DT=nullptr, const TargetLibraryInfo *TLI=nullptr)

Returns true if V is always a dereferenceable pointer with alignment greater or equal than requested.

LLVM_ABI bool isDereferenceablePointer(const Value *V, Type *Ty, const DataLayout &DL, const Instruction *CtxI=nullptr, AssumptionCache *AC=nullptr, const DominatorTree *DT=nullptr, const TargetLibraryInfo *TLI=nullptr)

Return true if this is always a dereferenceable pointer.

AnalysisManager< Function > FunctionAnalysisManager

Convenience typedef for the Function analysis manager.
