SpiderMonkey's Warp Upgrade Is Ready For Firefox 83
This blog post covers the architecture of Warp for speeding up the JIT compilation and optimizations, the IR handling, and more.
In that post they outline their next steps being the removal of the old code and architecture, which will likely happen for Firefox 85 and further improve the performance and memory usage. Ultimately they also hope to further enhance the IonMonkey JIT capabilities.
Firefox 83.0 is scheduled for release on 17 November.
