It basically sets in stone a bunch of behaviors that the enclave, the kernel, and the out-of-enclave code must follow. There are a bunch of things that the enclave can do to %rsp or %rip, for instance, that it is capable and/or permitted to do. The ABI seems entirely undocumented and rather lightly designed, which seems like something we should fix before this is merged. Also, for a feature as massive and complicated as this one, it seems irresponsible to not have a selftest. Is that not feasible for some reason?
