Dynamic relocation records

WebRelocation records : information about addresses referenced in this object file that the linker must adjust once it knows the final memory allocation. Additional information for debugging (e.g. map from line numbers in the source file to location in the code section). Example files: main.c : WebOct 31, 2024 · The dynamic loader performs *(Elf_Addr*)(base+r_offset) += base + addend;. For the REL format (used by arm and x86-32), addend is an implicit addend read from the to-be-relocated location. For the RELA format (used by most architectures), addend is r_addend stored in the relocation record.

Each address generated by a process (called a virtual address) is translated in hardware to a physical address.

Relocation is the process of assigning load addresses for position-dependent code and data of a program and adjusting the code and data to reflect the assigned addresses. Prior to the advent of multiprocess systems, and still in many embedded systems, the addresses for objects were absolute starting at a known location, often zero. Since multiprocessing systems dynamically link and switch between programs it became necessary to be able to relocate objects using position …
