Functions
Align llvm::assumeAligned (uint64_t Value)
Treats the value 0 as a 1, so Align is always at least 1.
bool llvm::isAligned (Align Lhs, uint64_t SizeInBytes)
Checks that SizeInBytes is a multiple of the alignment.
bool llvm::isAddrAligned (Align Lhs, const void *Addr)
Checks that Addr is a multiple of the alignment.
uint64_t llvm::alignTo (uint64_t Size, Align A)
Returns a multiple of A needed to store Size bytes.
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.
uintptr_t llvm::alignAddr (const void *Addr, Align Alignment)
Aligns Addr to Alignment bytes, rounding up.
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.
uint64_t llvm::offsetToAlignedAddr (const void *Addr, Align Alignment)
Returns the necessary adjustment for aligning Addr to Alignment bytes, rounding up.
unsigned llvm::Log2 (Align A)
Returns the log2 of the alignment.
Align llvm::commonAlignment (Align A, uint64_t Offset)
Returns the alignment that satisfies both alignments.
unsigned llvm::encode (MaybeAlign A)
Returns a representation of the alignment that encodes undefined as 0.
MaybeAlign llvm::decodeMaybeAlign (unsigned Value)
Dual operation of the encode function above.
unsigned llvm::encode (Align A)
Returns a representation of the alignment, the encoded value is positive by definition.
bool llvm::operator== (Align Lhs, uint64_t Rhs)
Comparisons between Align and scalars. Rhs must be positive.
bool llvm::operator!= (Align Lhs, uint64_t Rhs)
bool llvm::operator<= (Align Lhs, uint64_t Rhs)
bool llvm::operator>= (Align Lhs, uint64_t Rhs)
