Unlocking Javascript: V8 on RISC-V
summary
A V8 backend for RISC-V (rv64g) compiles and runs JavaScript and WASM using the V8 assembler, embedded simulator and node.js; the port passes about 17,000 V8 tests (≈99% on simulator and after fixes ≈99% on HiFive Unleashed hardware) and about 3,000 node tests with ~13 failures. Build uses the turbo assembler/CSA layering, d8 for debugging, npm for examples, and an embedded simulator to speed development; roadmap targets HiFive Unleashed and upstreaming.
