...ontrol of the process address space layout. It seems I may ultimately need to use Hypervisor.framework however that is a lot more work in the short term. I actually thought about mentioning Hypervisor.framework, but I was not sure about your use case. If you need full control of the address space (PAGE_ZERO control, overriding the shared cache mappings, etc) that is really the only supported mechanism. > The issue I am having with libSystem.dylib is the lack of weak linkage (versus weak_import) i.e. weak aliases. I don’t want to use a wrapper binary with DYLD_INSERT_LIBRARIES. I want to interpose...
