" summary

A Java-written JIT called Graal compiles and installs machine code into HotSpot at runtime using meta, code and interpreter APIs, so developers generate, inspect and run compiler output without C++ edits or full VM rebuilds. The project ships an IDE-friendly hex tool, supports Eclipse/NetBeans, and runs benchmarks (SPECjvm2008, SPECjbb, DaCapo), reporting about 26% faster than the client compiler in recent runs. Features include node intrinsics, snippet-based lowering, incremental inlining, customizable phase plans and a prototype interpreter that actually executes within the VM.
