#include "[llvm/Support/Alignment.h](Alignment%5F8h%5Fsource.html)"

This struct is a compact representation of a valid (non-zero power of two) alignment.

It is suitable for use as static global constants.

Definition at line 39 of file Alignment.h.

◆ Align() [1/4]

Default is byte-aligned.

Referenced by Constant().

◆ Align() [2/4]

Do not perform checks in case of copy/move construct/assign, because the checks have been performed when building Other.

References llvm::Other.

◆ Align() [3/4]

◆ Align() [4/4]

◆ Constant()

template<size_t kValue>

◆ Of()

template<typename T>

Allow constructions of constexpr Align from types.

Compile time equivalent to Align(alignof(T)).

◆ operator=() [1/2]

◆ operator=() [2/2]

◆ previous()

◆ value()

This is a hole in the type system and should not be abused.

Needed to interact with C for instance.
