Evan Cheng The LLVM Code Generator - An overview of the LLVM generic code generator design and changes to it that are coming in the future.
Nick Lewycky Introduction To Predicate Simplifier - A review of the design and implementation of LLVM's Predicate Simplifier Pass, otherwise known as VRP (Value Range Propagation).
Reid Spencer HLVM - An overview of HLVM, its current status and its goals after integration with LLVM.


Session 2:
Using LLVM

slides (PPT)
John Criswell Secure Virtual Architecture - A presentation on our research to create a virtual machine that operates below the operating system and a brief introduction to some of the novel security capabilities that our architecture can enable.
Steve Naroff New LLVM C Front-end - This talk describes a new from-scratch C frontend (which is aiming to support Objective C and C++ someday) for LLVM, built as a native part of the LLVM system and in the LLVM design style.
slides video Chris Lattner LLVM in OpenGL and for Dynamic Languages - A presentation put together in 10 minutes, talking about LLVM being used for OpenGL and some speculative talk about dynamic languages.


Session 3:

MediaLeaderDiscussion Topic
video Christopher Lamb Concurrency Primitives - For multi-threaded shared memory models.
video Reid Spencer LLVM Roadmap - Does the development community care to disclose and maintain advance information about what is being worked on?
video Chris Lattner Adoption Goals - While our adoption has increased greatly recently, we're still tiny compared to other compiler and virtual machine systems.
