Partial static single information form
Summary
The article explains Partial SSI, a pragmatic approach to refining types within SSA-based IR to enable optimizations. It covers where to insert type refinements, trade-offs with compile-time vs run-time, and how partial SSI compares to full SSI across various compilers and projects, with examples from ZJIT, Graal, and Cinder. It concludes that partial SSI can be effective without implementing full SSI.
