◆ aliasAnalysisGetModRefInfo()

static ModRefInfo llvm::sandboxir::Utils::aliasAnalysisGetModRefInfo	(	BatchAAResults &	BatchAA,
		const Instruction *	I,
		const std::optional< MemoryLocation > &	OptLoc
	)

inlinestatic

Equivalent to BatchAA::getModRefInfo().

◆ atLowerAddress()

template<typename LoadOrStoreT >

static bool llvm::sandboxir::Utils::atLowerAddress	(	LoadOrStoreT *	I0,
		LoadOrStoreT *	I1,
		ScalarEvolution &	SE
	)

inlinestatic

\Returns true if I0 accesses a memory location lower than I1.

Returns false if the difference cannot be determined, if the memory locations are equal, or if I1 accesses a memory location greater than I0.

◆ getExpectedType()

static Type * llvm::sandboxir::Utils::getExpectedType ( const Value * V )

inlinestatic

\Returns the expected type of Value V.

For most Values this is equivalent to getType, but for stores returns the stored type, rather than void, and for ReturnInsts returns the returned type.

◆ getExpectedValue()

static Value * llvm::sandboxir::Utils::getExpectedValue ( const Instruction * I )

inlinestatic

\Returns the expected Value for this instruction.

For most instructions, this is the instruction itself, but for stores returns the stored operand, and for ReturnInstructions returns the returned value.
