This pull request introduces Bytecode DSL, a new framework for implementing bytecode interpreters. Bytecode DSL consumes a user-provided specification (including a set of node-like operations) to generate a bytecode interpreter.

Tips for reviewing:

  1. The first commit is the one of interest. The next two two commits are migration code, and the ones after are bug/gate/feedback fixes (which will be squashed into the first commit before merge). It may be helpful to read some of the docs and tutorials to get started.
  2. The generated code is intended to be human readable, so it may be helpful to check out and build the test interpreters directly if you wish to look at generated code.
  3. @Bind.DefaultExpression was added in this PR. The changes are (unfortunately) too entangled with Bytecode DSL to easily pull out, so some of the changes here just remove redundant bind expressions.

Also read the changelog: https://github.com/oracle/graal/pull/9556/files#diff-0152a89226e848ea31c4005b3c57079db79ff8112c4278d28237c8b9ed24dc16

Features:

  • Tiered Interpretation (uncached -> cached)
  • Boxing elimination + Quickening
  • Reparsing (Lazy sources and Instrumentation)
  • Serialization/Deserialization
  • Coroutines
  • Tag and Bytecode Based Instrumentation
  • Local or Global Scoping of Variables
  • AST node proxying (for migration)
  • Several Tutorials & Guides
