linksem 0.8 · OCaml Package

The abis module is the top-level module for all ABI related code, including * some generic functionality that works across all ABIs, and a primitive attempt * at abstracting over ABIs for purposes of linking.

Relocation operators and their validity on a given platform

amd64_base_addr rr site_addr computes back the base address at which a * shared object has been loaded into memory during execution. It's kind of * lame to have this function because the linker will do the opposite operation * when relocating, but I don't want to add a new argument to the reloc * function.

amd64_reloc r yields a function that applies relocations of type r.
