==Graal - A Bytecode Agnostic Compiler for the JVM==
;Speakers: [http://labs.oracle.com/people/mybio.php?c=1400 Thomas Würthinger] (presentation): thomas.wuerthinger (at) oracle.com
:[http://www.ssw.uni-linz.ac.at/General/Staff/LS/ Lukas Stadler] (workshop): stadler (at) ssw.jku.at
;Project: http://wikis.sun.com/display/MaxineVM/Graal
;Slides: [[Media:GraalJVMSummit2011.pdf|Presentation]]
: [[Media:2011 Stadler Graal workshop.pdf|Workshop]]

===Abstract===
Graal is a just-in-time compiler written in Java that works with both the HotSpot VM and the Maxine VM [http://wikis.sun.com/display/MaxineVM/Home]. It is based on a port of the HotSpot client compiler from C++ to Java, but it takes new approaches in some key areas, most notably the intermediate representation (IR): Graal's IR consists of an SSA-form, "sea-of-nodes" program dependence graph.

Java as the implementation language makes it much easier to let frameworks and applications interact with and extend the compiler.
We think that this is a key aspect of Graal. The presentation provides an overview of Graal and gives examples for possible compiler extensions. The workshop should lead to discussions about which additional features Graal could provide that would benefit language implementors.

=== Abstract ===

Continuations for the Hotspot JVM — Lukas Stadler

Continuation support is part of the MLVM effort. They are a powerful concept that allows implementation of many advanced language features like coroutines, green threads, etc. This presentation covers the basic concepts of the lazy continuation mechanism and the details of the actual implementation in the JVM.

= Background =
This project is part of a long-term collaboration between the HotSpot compiler group at Sun Microsystems and the Institute of System Software at the Johannes Kepler University Linz.

For a list of publications that were results of this collaboration (topics include SSA form, linear scan register allocation, ABCE, object inlining, escape analysis, compiler graph visualization tools) see:
