I am working on linker development for an open source project. The target architecture is AMD_X86_X64. In AMD_X86_X64 specification The relocation types' calculations for ELF are declared for example, R_X86_64_64
the calculation is S + A. How to do these calculations in COFF I can't find them online ?
