Lecture
This lecture explores the process of efficiently implementing a new programming language in GraalVM, a high-performance multi-lingual virtual machine. The instructor demonstrates steps to create a language, from defining an executable AST to implementing an interpreter loop. The lecture delves into partial evaluation, a technique used to specialize interpreter code to a given AST, leading to significant performance improvements. Additionally, memory out-of-bounds access profiling and techniques to implement memory reads and writes in a Truffle interpreter are discussed. The lecture concludes with insights on resetting Truffle frame-slot values and the impact of escape analysis on eliminating reads and writes during compilation.
