Functions
bool	shouldPassIndirectly (CodeGenModule &CGM, ArrayRef< llvm::Type * > types, bool asReturnValue)
	Should an aggregate which expands to the given type sequence be passed/returned indirectly under swiftcall?

CharUnits	getMaximumVoluntaryIntegerSize (CodeGenModule &CGM)
	Return the maximum voluntary integer size for the current target.

CharUnits	getNaturalAlignment (CodeGenModule &CGM, llvm::Type *type)
	Return the Swift CC's notion of the natural alignment of a type.

bool	isLegalIntegerType (CodeGenModule &CGM, llvm::IntegerType *type)
	Is the given integer type "legal" for Swift's perspective on the current platform?

bool	isLegalVectorType (CodeGenModule &CGM, CharUnits vectorSize, llvm::VectorType *vectorTy)
	Is the given vector type "legal" for Swift's perspective on the current platform?

void	legalizeVectorType (CodeGenModule &CGM, CharUnits vectorSize, llvm::VectorType vectorTy, llvm::SmallVectorImpl< llvm::Type > &types)
	Turn a vector type in a sequence of legal component vector types.

bool	mustPassRecordIndirectly (CodeGenModule &CGM, const RecordDecl *record)
	Is the given record type required to be passed and returned indirectly because of language restrictions?

ABIArgInfo	classifyReturnType (CodeGenModule &CGM, CanQualType type)
	Classify the rules for how to return a particular type.

ABIArgInfo	classifyArgumentType (CodeGenModule &CGM, CanQualType type)
	Classify the rules for how to pass a particular type.

void	computeABIInfo (CodeGenModule &CGM, CGFunctionInfo &FI)
	Compute the ABI information of a swiftcall function.

bool	isSwiftErrorLoweredInRegister (CodeGenModule &CGM)
	Is swifterror lowered to a register by the target ABI?
