nx_author.nx

nx_author.nx -- the team AUTHORS a new technique from its own diagnosis, by EXPERIMENT. Last loops the team diagnosed "the competitor used a mnemonic I lack: imul" and I had to tell it (or pre-stock) what imul does. This removes me: the team LEARNS the instruction's semantics itself. It emits the instruction (in the form it observed in the competitor's objdump: `imulq $K, %rdi, %rax`), RUNS it on several (K,x) probes, observes the outputs, and INFERS which operation it computes by testing hypotheses {mul,add,sub,xor,and,or,shl} against the observed input->output pairs. The hypothesis that matches ALL probes is the learned semantics. Discovery by experiment -- the team teaches ITSELF a new primitive. license_tier: ORIGINAL
