class MCBoundaryAlignFragment

Declaration

class MCBoundaryAlignFragment : public MCFragment { /* full declaration omitted */ };

Description

Represents required padding such that a particular other set of fragments does not cross a particular power-of-two boundary. The other fragments must follow this one within the same section.

Declared at: llvm/include/llvm/MC/MCFragment.h:578

Inherits from: MCFragment

Member Variables

private llvm::Align AlignBoundary

The alignment requirement of the branch to be aligned.

private const llvm::MCFragment* LastFragment = nullptr

The last fragment in the set of fragments to be aligned.

private uint64_t Size = 0

The size of the fragment. The size is lazily set during relaxation, and is not meaningful before that.

private const llvm::MCSubtargetInfo& STI

When emitting Nops some subtargets have specific nop encodings.

Inherited from MCFragment:

protected HasInstructions
