Overview

One relocation inside a global's .data image. offset is the byte offset of the 8-byte pointer slot within that global. kind is :symbol for the address of another file-scope object — symbol names it, resolved as an absolute 64-bit address (a "&global" or a decayed global array) — or :string for a string literal, where string_id indexes the translation unit's string pool and the compiler resolves it to a .rodata offset. The unused field is nil for each kind. addend is a constant byte displacement added to the base address (0 for a bare "&global" or string, non-zero for a computed address constant such as "&arr", "arr + n" or "&rec.member"); it becomes the R_X86_64_64 relocation's r_addend.
