Linkage in the Third Millenium. Ideas, Innovations, Experiments and Prototypes for Fl...
summary
Zephyr claims it has pushed the v6 UNIX linker past its limits and documents concrete pains: link-time hacks like multi-stage link and Python postprocessing, a surprising 18 relocation types on arm64, and a 512 MB address-gap bug from mixing dot and at addresses. The build actually uses static libraries as dependency hacks, objectcopy scripts to reassign symbols, and a working but fragile IMR/cache segregation for Intel audio DSP; a cleaner Python-extensible linker and LTO integration is proposed but the prototype is still missing.
