 Emscripten is an open source compiler that converts LLVM bitcode to JavaScript. JavaScript is a fairly unusual target for compilation, being a high-level dynamic language instead of a low-level CPU assembly, but efficient compilation to JavaScript is useful because of the ubiquity of web browsers which use it as their standard language. This talk will detail how Emscripten utilizes LLVM and clang to convert C/C++ into JavaScript, and cover the specific challenges that compiling to JavaScript entails, such as the lack of goto statements, while on the other hand making other aspects of compilation simpler, for example having native exception handling support. Some such issues are general and have to do with JavaScript itself, but specific challenges with Emscripten's interaction with LLVM will also be described, as well as opportunities for better integration between the projects in the future.

 Code size reduction is a critical goal for compiler optimizations targeting embedded applications. While LLVM continues to improve its performance optimization capabilities, it is currently still lacking a robust set of optimizations specifically targeting code size. In our talk, we will describe an optimization pass that aims to reduce code size by merging similar functions at the IR level. Significantly extending the existing MergeFunctions optimization, the pass is capable of merging multiple functions even if there are minor differences between them. A number of heuristics are used to determine when merging of functions is profitable. Alongside hash tables, these also ensure that compilation time remains at an acceptable level. We will describe our experience of using this new optimization pass to reduce the code size of a significant embedded application at Qualcomm Innovation Center by 2%.

 Instcombine and Selection DAG optimizations, although usually simple, can easily hide bugs.
 We've had many cases in the past where these optimizers were producing wrong code in certain corner cases.
 In this talk I'll describe a way to prove the correctness of such optimization using an off-the-shelf SMT solver (bit-vector theory).  I'll give examples of past bugs found in these optimizations, how to encode them into SMT-Lib 2 format, and how to spot the bugs.

 Profile Guided Optimization (PGO) is one of the most fundamental weaknesses in the LLVM optimization portfolio. We have had several attempts to build it, and to this day we still lack a holistic platform for driving optimizations through profiling. This talk will consist of three light-speed crash courses on where PGO is in LLVM, where it needs to be, and how several of us are working to get it there.
 <br>
 First, we will present some motivational background on what PGO is good for and what it isn't. We will cover exactly how profile information interacts with the LLVM optimizations, the strategies we use at a high level to organize and use profile information, and the specific optimizations that are in turn driven by it. Much of this will cover infrastructure as it exists today, with some forward-looking information added into the mix.

 In 2012, MC Hammer was presented as a testing infrastructure to exhaustively verify the MC layer implementation for the ARM backend. Within ARM we have been working to fix any bugs and we have reached the point where all but one problem remains unsolved.  Some of the issues discovered in this process have proven to be excessively difficult to fix. The purpose of the presentation is to give a brief rundown of the major headaches and to suggest possible courses of action for improving LLVM infrastructure.

 Modern DSP architectures such as Hexagon use VLIW instruction packets, which are not well suited to the single instruction streaming model of the LLVM MC layer. Developing an assembler for Hexagon presents unique challenges in the MC layer, especially since Hexagon leverages an optimizing assembler to achieve maximum performance. It is possible to support VLIW within the MC layer by treating every MC instruction as a bundle, and adding all instructions in a packet as sub instruction operands. Furthermore, subclassing MCInst to create a target-specific type of MCInst allows us to capture packet information that will be used to make optimization decisions prior to emitting the code to object format.
