Igalia and TC39
Igalia maintains the MIPS and ARMv7 ports of JSC, including their support in the optimizing compiler (JIT). The JIT has been found to be critical for performance, based on benchmarks of interactive performance of client applications. Maintenance of these ports over time is important in order to keep up-to-date with improvements in performance, security and features from upstream developments.
