Methods

¶MemSDNode(unsigned int Opc,
          unsigned int Order,
          const llvm::DebugLoc& dl,
          llvm::SDVTList VTs,
          llvm::EVT memvt,
          llvm::MachineMemOperand* MMO)

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1270

Parameters

unsigned int Opc

unsigned int Order

const llvm::DebugLoc& dl

llvm::SDVTList VTs

llvm::EVT memvt

llvm::MachineMemOperand* MMO

¶static bool classof(const llvm::SDNode* N)

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1384

Parameters

const llvm::SDNode* N

¶llvm::AAMDNodes getAAInfo() const

Description

Returns the AA info that describes the dereference.

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1310

¶unsigned int getAddressSpace() const

Description

Return the address space for the associated pointer

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1353

¶llvm::Align getAlign() const

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1278

¶unsigned int getAlignment() const

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1280

¶const llvm::SDValue& getBasePtr() const

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1367

¶const llvm::SDValue& getChain() const

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1365

¶llvm::MachineMemOperand* getMemOperand() const

Description

Return a MachineMemOperand object describing the memory reference performed by operation.

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1346

¶llvm::EVT getMemoryVT() const

Description

Return the type of the in-memory value.

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1342

¶llvm::AtomicOrdering getMergedOrdering() const

Description

Return a single atomic ordering that is at least as strong as both the success and failure orderings for an atomic operation. (For operations other than cmpxchg, this is equivalent to getSuccessOrdering().)

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1328

¶llvm::Align getOriginalAlign() const

Description

Returns alignment and volatility of the memory access

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1277

¶const llvm::MachinePointerInfo& getPointerInfo()
    const

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1348

¶const llvm::MDNode* getRanges() const

Description

Returns the Ranges that describes the dereference.

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1313

¶unsigned int getRawSubclassData() const

Description

Return the SubclassData value, without HasDebugValue. This contains an encoding of the volatile flag, as well as bits used by subclasses. This function should only be used to compute a FoldingSetNodeID value. The HasDebugValue bit is masked out because CSE map needs to match nodes with debug info with nodes without debug info. Same is about isDivergent bit.

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1288

¶int64_t getSrcValueOffset() const

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1307

¶llvm::AtomicOrdering getSuccessOrdering() const

Description

Return the atomic ordering requirements for this memory operation. For cmpxchg atomic operations, return the atomic ordering requirements when store occurs.

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1321

¶SyncScope::ID getSyncScopeID() const

Description

Returns the synchronization scope ID for this memory operation.

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1316

¶bool isAtomic() const

Description

Return true if the memory operation ordering is Unordered or higher.

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1331

¶bool isDereferenceable() const

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1303

¶bool isInvariant() const

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1304

¶bool isNonTemporal() const

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1302

¶bool isSimple() const

Description

Returns true if the memory operation is neither atomic or volatile.

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1339

¶bool isUnordered() const

Description

Returns true if the memory operation doesn't imply any ordering constraints on surrounding memory operations beyond the normal memory aliasing rules.

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1336

¶bool isVolatile() const

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1301

¶bool readMem() const

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1273

¶void refineAlignment(
    const llvm::MachineMemOperand* NewMMO)

Description

Update this MemSDNode's MachineMemOperand information to reflect the alignment of NewMMO, if it has a greater alignment. This must only be used when the new alignment applies to all users of this MachineMemOperand.

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1361

Parameters

const llvm::MachineMemOperand* NewMMO

¶bool writeMem() const

Declared at: llvm/include/llvm/CodeGen/SelectionDAGNodes.h:1274
