Rose::BinaryAnalysis::Disassembler::Null Class Reference

Description

Disassembler for nothing.

This disassembler is a stub that can be used when no ISA is specified. It's never chosen automatically. It has unknown byte order. It always decodes to an unknown instruction that's one byte long.

Member Function Documentation

◆ clone()

virtual Base::Ptr Rose::BinaryAnalysis::Disassembler::Null::clone ( ) const
overridevirtual

Creates a new copy of a disassembler.

The new copy has all the same settings as the original.

Thread safety: The thread safety of this virtual method depends on the implementation in the subclass.

Implements Rose::BinaryAnalysis::Disassembler::Base.

◆ disassembleOne()

virtual SgAsmInstruction * Rose::BinaryAnalysis::Disassembler::Null::disassembleOne ( const MemoryMap::Ptr map,
rose_addr_t  start_va,
AddressSet successors = NULL 
)
overridevirtual

This is the lowest level disassembly function and is implemented in the architecture-specific subclasses.

It disassembles one instruction at the specified virtual address. The map is a mapping from virtual addresses to buffer and enables instructions to span file segments that are mapped contiguously in virtual memory by the loader but which might not be contiguous in the file. The instruction's successor virtual addresses are added to the optional successor set (note that successors of an individual instruction can also be obtained via Architecture::Base::getSuccessors). If the instruction cannot be disassembled then an exception is thrown and the successors set is not modified.

Thread safety: The safety of this method depends on its implementation in the subclass. In any case, no other thread can be modifying the MemoryMap or successors set at the same time.

Implements Rose::BinaryAnalysis::Disassembler::Base.

◆ makeUnknownInstruction()

virtual SgAsmInstruction * Rose::BinaryAnalysis::Disassembler::Null::makeUnknownInstruction ( const Exception )
overridevirtual

Makes an unknown instruction from an exception.

Thread safety: The safety of this method depends on its implementation in the subclass.

Implements Rose::BinaryAnalysis::Disassembler::Base.
