JIT documentation

Abstract

When PyPy is translated into an executable such as pypy-c, the executable contains a full virtual machine that can optionally include a Just-In-Time compiler. This JIT compiler is generated automatically from the interpreter that we wrote in RPython.

This JIT Compiler Generator can be applied on interpreters for any language, as long as the interpreter itself is written in RPython and contains a few hints to guide the JIT Compiler Generator.

  • Overview: motivating our approach
  • Notes about the current work in PyPy
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
