Detailed Description

MachOAbstractFixupEntry is an abstract class representing a fixup in a MH_DYLDLINK file.

Fixups generally represent rebases and binds. Binds also subdivide into additional subtypes (weak, lazy, reexport).

The two concrete subclasses of MachOAbstractFixupEntry are:

MachORebaseBindEntry - for dyld opcode-based tables, including threaded- rebase, where rebases are mixed in with other bind opcodes. MachOChainedFixupEntry - for pointer chains embedded in data pages.

◆ address()

uint64_t MachOAbstractFixupEntry::address ( ) const

Returns: the location of this fixup as a VM Address. For the VM Address this fixup is pointing to, use pointerValue().

◆ ordinal()

int MachOAbstractFixupEntry::ordinal ( ) const

Definition at line 3322 of file MachOObjectFile.cpp.

References Ordinal.

◆ pointerValue()

uint64_t llvm::object::MachOAbstractFixupEntry::pointerValue ( ) const

inline

Returns: the VM Address pointed to by this fixup. Use pointerValue() to compare against other VM Addresses, such as section addresses or segment vmaddrs.

Definition at line 346 of file MachO.h.

References PointerValue.

◆ rawValue()

uint64_t llvm::object::MachOAbstractFixupEntry::rawValue ( ) const

inline

Returns: the raw "on-disk" representation of the fixup. For Threaded rebases and Chained pointers these values are generally encoded into various different pointer formats. This value is exposed in API for tools that want to display and annotate the raw bits.
