SAN19-106 What’s new in VIXL 2019?
VIXL is a ARMv8 Runtime Code Generation Library which contains three components:
- Programmatic assemblers to generate A64, A32 or T32 code at runtime.
- Disassemblers that can print any instruction emitted by the assemblers.
- Simulator can simulate any instruction emitted by the A64 assembler on x86 and ARM platform. It is configurable, vector length for SVE, for example, and it supports register tracing during the execution.

In this talk, we're going to introduce:
- What is VIXL? It is already deployed and is considered “mature”, for example, it has been adopted by Android ART compiler for its ARM backends: AArch64 and AArch32.
- CPU feature management and detection.
- New Armv8.x instructions support, e.g. BTI, PAuth, etc.
- New SVE (Scalable Vector Extension) support.

SAN19-227 Technology For Everyone (Introductory)
The goal of the presentation is to help people in non-development roles understand and navigate the complex world of technology.  All are welcome. Those with a technical background may find the session too introductory.

The first part of the presentation looks at some of the deliverables found on releases.linaro.org and how they fit in a typical product development life cycle. More specifically we start with how the 96boards standard helps developers get going at the prototyping phase of a project and speed up time to market. From there we explore the concept of toolchains and how programmers use them in their daily work. The third aspect of the presentation gives an overview of what libraries are and the advantages of using them when building a system.

SAN19-506 BuildKit: A next generation image builder toolkit
BuildKit solves many problems of "docker build", instead of replace the "docker build", it evolves to be an independent project but still under the umbrella of moby.

In this presentation, I am going to talk the key issues that BuildKit addresses, such as concurrent dependency resolution, much faster image build with cache import/output, and how to avoid to leak credential while still allow accessing private assets.

You will see how the BuildKit could be used in conjunction with 'docker', particularly, we will see how BuildKit supports multi-arch image build for ARM platform, and the Docker as well. Actually, the cutting-edge innovation of "docker buildx" is right based on BuildKit, besides, couple of demo on top of ARM platform will be given during the session.

Some performance data will be given as well to compare with traditional "docker build".

SAN19-514 Graal Compiler Optimizations on AArch64.
Graal is a dynamic compiler that integrates with the HotSpot JVM and converts Java bytecode to native machine code at runtime. It can be a replacement of the C2 compiler in Hotspot with the basic advantage that Graal is written in Java rather than C++, which makes it probably safety and easier to maintain and extend. Besides, Graal compiler has a focus on high performance so it's also a big part of what makes Java as faster as it is.

Currently Graal has added many optimization mechanisms like speculative optimizations, inlining, partial escape analysis, lowering snippets, etc. Even so, compared to the C2 compiler, Graal still lose some optimizations and new features of OpenJDK especially for AArch64. Its performance could be better.

This presentation explores the status of Graal Optimization on AArch64, together with the performance data of some benchmarks. Some of the focus is on the recent changes and the improvement in AArch64 port which Arm contributes to. Some of the future works may also be introduced.
