class MCSectionELF

Declaration

class MCSectionELF : public MCSection { /* full declaration omitted */ };

Description

This represents a section on linux, lots of unix variants and some bare metal systems.

Declared at: llvm/include/llvm/MC/MCSectionELF.h:26

Inherits from: MCSection

Member Variables

private unsigned int Type

This is the sh_type field of a section, drawn from the enums below.

private unsigned int Flags

This is the sh_flags field of a section, drawn from the enums below.

private unsigned int UniqueID

private unsigned int EntrySize

The size of each entry in this section. This size only makes sense for sections that contain fixed-sized entries. If a section does not contain fixed-sized entries 'EntrySize' will be 0.

private const PointerIntPair<const llvm::MCSymbolELF*, 1, bool> Group

The section group signature symbol (if not null) and a bool indicating whether this is a GRP_COMDAT group.

private const llvm::MCSymbol* LinkedToSym

Used by SHF_LINK_ORDER. If non-null, the sh_link field will be set to the section header index of the section where LinkedToSym is defined.

Inherited from MCSection:

protected Name
