Classes
struct	llvm::Align
	This struct is a compact representation of a valid (non-zero power of two) alignment. More...
struct	llvm::MaybeAlign
	This struct is a compact representation of a valid (power of two) or undefined (0) alignment. More...

Namespaces
	llvm
	This is an optimization pass for GlobalISel generic memory operations.

Macros
#define	ALIGN_CHECK_ISPOSITIVE(decl)   assert(decl > 0 && (#decl " should be defined"))

Functions
Align	llvm::assumeAligned (uint64_t Value)
	Treats the value 0 as a 1, so Align is always at least 1. More...
bool	llvm::isAligned (Align Lhs, uint64_t SizeInBytes)
	Checks that SizeInBytes is a multiple of the alignment. More...
bool	llvm::isAddrAligned (Align Lhs, const void *Addr)
	Checks that Addr is a multiple of the alignment. More...
uint64_t	llvm::alignTo (uint64_t Size, Align A)
	Returns a multiple of A needed to store Size bytes. More...
uint64_t	llvm::alignTo (uint64_t Size, Align A, uint64_t Skew)
	If non-zero Skew is specified, the return value will be a minimal integer that is greater than or equal to Size and equal to A * N + Skew for some integer N. More...
uintptr_t	llvm::alignAddr (const void *Addr, Align Alignment)
	Aligns Addr to Alignment bytes, rounding up. More...
uint64_t	llvm::offsetToAlignment (uint64_t Value, Align Alignment)
	Returns the offset to the next integer (mod 2**64) that is greater than or equal to Value and is a multiple of Align. More...
uint64_t	llvm::offsetToAlignedAddr (const void *Addr, Align Alignment)
	Returns the necessary adjustment for aligning Addr to Alignment bytes, rounding up. More...
unsigned	llvm::Log2 (Align A)
	Returns the log2 of the alignment. More...
Align	llvm::commonAlignment (Align A, uint64_t Offset)
	Returns the alignment that satisfies both alignments. More...
unsigned	llvm::encode (MaybeAlign A)
	Returns a representation of the alignment that encodes undefined as 0. More...
MaybeAlign	llvm::decodeMaybeAlign (unsigned Value)
	Dual operation of the encode function above. More...
unsigned	llvm::encode (Align A)
	Returns a representation of the alignment, the encoded value is positive by definition. More...
bool	llvm::operator== (Align Lhs, uint64_t Rhs)
	Comparisons between Align and scalars. Rhs must be positive. More...
bool	llvm::operator!= (Align Lhs, uint64_t Rhs)
bool	llvm::operator<= (Align Lhs, uint64_t Rhs)
bool	llvm::operator>= (Align Lhs, uint64_t Rhs)
bool	llvm::operator< (Align Lhs, uint64_t Rhs)
bool	llvm::operator> (Align Lhs, uint64_t Rhs)
bool	llvm::operator== (Align Lhs, Align Rhs)
