One Compiler - Graal VM and Substrate VM Overview

Explore Christian Wimmer's 40-minute conference talk from the JVM Language Summit 2016 on the One Compiler concept. Delve into the intricacies of Java HotSpot VM, Nashorn, and Truffle system structures. Learn about Graal VM performance, Substrate VM execution models, and key features of Graal. Discover deoptimization techniques, low-level memory access using Word type, and how Java annotations import elements. Gain insights into Graal's capabilities as a static analysis framework and understand the evolution of compiler stacks in Java environments.
