class MCAlignFragment

Declaration

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

Description

An ilist node that can access its parent list. Requires \c NodeTy to have \a getParent() to find the parent node, and the\c ParentTy to have \a getSublistAccess() to get a reference to the list.

Declared at: llvm/include/llvm/MC/MCFragment.h:294

Member Variables

private llvm::Align Alignment

The alignment to ensure, in bytes.

private bool EmitNops

Flag to indicate that (optimal) NOPs should be emitted instead of using the provided value. The exact interpretation of this flag is target dependent.

private int64_t Value

Value to use for filling padding bytes.

private unsigned int ValueSize

The size of the integer (in bytes) of \p Value.

private unsigned int MaxBytesToEmit

The maximum number of bytes to emit; if the alignment cannot be satisfied in this width then this fragment is ignored.

private const llvm::MCSubtargetInfo* STI

When emitting Nops some subtargets have specific nop encodings.

Inherited from MCFragment:
