Description

Relocation record.

A relocation record describes how the new encoded instructions need to have their encodings adjusted when they're placed at some specific memory address. This is necessary because the instructions are encoded by the user before an address is chosen by the CodeInserter.

Each relocation entry applies to a specific index in the vector of bytes of the encoded instructions. This is called the relocation offset. The type of the relocation indicates which predefined function is used to calculate the value that is to be written to that output offset, and value is an optional argument that gets passed to that function.

◆ Relocation()

Rose::BinaryAnalysis::CodeInserter::Relocation::Relocation	(	size_t	offset,
		RelocType	type,
		rose_addr_t	value
	)

inline

Constructor.

Construct a relocation that will change the value at the specified offset in the replacement code. The size of the area overwritten as well as the algorithm for computing the new bytes are determined by the relocation type. The value is one of the inputs to the relocation algorithm (the other is the virtual address of the byte at the specified offset in the replacement.
