Tutorial: High Level Sail Overview
summary
Sail is the canonical golden model used to generate signatures for ACT compatibility testing and to specify RISC‑V behavior precisely; Vector support is a massive effort — about 10,000 lines of Vector being split into smaller PRs — and a JIT prototype reports a 10× Linux boot speedup as proof‑of‑concept. Work adds YAML RISC‑V config ingestion so Sail can read vlen and other platform fields, uses asserts to feed the type checker, exposes a C foreign‑function interface, still lacks a full cache/coherency model, and explores Sail as a Service for running ELFs.
