Dragons have connotations of power, speed and intelligence, and can also be sleek, elegant, and modular (err, maybe not). In addition, there is a series of influential compiler books going back to 1977 which featured dragons on the cover. LLVM DEBIAN/UBUNTU PACKAGES This for both the stable, old-stable and development branches (currently 11, 12 and 13). Packages are built using stage2 and extremely similar to the one shipping in Debian & Ubuntu. The packages provide LLVM + Clang + compiler-rt + polly + LLDB + LLD + libFuzzer + libc++ + libc++abi + openmp + libclc. LLVM: LLVM::LOOPINFO CLASS REFERENCE Checks if moving a specific instruction can break LCSSA in any loop. Return true if moving Inst to before NewLoc will break LCSSA, assuming that the function containing Inst and NewLoc is currently in LCSSA form.. Definition at line 1138 of file LoopInfo.h.. References assert(), llvm::Instruction::getFunction(), llvm::Instruction::getParent(), llvm::User::operands(), and CLANG C LANGUAGE FAMILY FRONTEND FOR LLVM Clang: a C language family frontend for LLVM. The Clang project provides a language front-end and tooling infrastructure for languages in the C language family (C, C++, Objective C/C++, OpenCL, CUDA, and RenderScript) for the LLVM project. Both a GCC-compatible compiler driver (clang) and an MSVC-compatible compiler driver (clang-cl.exe)

are provided.

WHAT IS CLANGD?

What is clangd? clangd understands your C++ code and adds smart features to your editor: code completion, compile errors, go-to-definition and more. clangd is a language server that can work with many editors via a plugin. Here’s Visual Studio Code with the clangd plugin, demonstrating code completion: clangd is based on the

Its purpose is to provide an extensible framework for diagnosing and fixing typical programming errors, like style violations, interface misuse, or bugs that can be deduced via static analysis. clang-tidy is modular and provides a convenient interface for writing new checks. LLVM SNAPSHOT BUILDS Windows snapshot builds. We provide a periodically updated installer for Windows: Windows installer (64-bit) (.sig) , based on Git commit 6923b0a7 (28 August 2020). If there is a previous version installed, the installer provides an option to uninstall it. Currently, the package includes clang , clang-format , lld, and the AddressSanitizer DOWNLOAD LLVM RELEASES Currently, LLVM releases are distributed under the University of Illinois Open Source License, an OSI-approved license. However, LLVM version 8 will be the last release under that license as LLVM is moving to a new license structure. You can find more details about this in the developer's policy.

GETTING STARTED

Other build systems, using Bear. Bear is a tool to generate a compile_commands.json file by recording a complete build.. For a make-based build, you can run make clean; bear -- make to generate the file (and run a clean build!).. Other tools can also generate this file. See the compile_commands.json specification.. compile_flags.txt. If all files in a project use the same build flags, you can LLVM: LLVM::POINTERTYPE CLASS REFERENCE bool llvm::PointerType::isOpaqueOrPointeeTypeMatches. (. Type *. Ty. ) inline. Return true if either this is an opaque pointer type or if this pointee type matches Ty. Primarily used for checking if an instruction's pointer operands are valid types. Will be useless after non-opaque pointers are removed. CLANG - GETTING STARTED Getting Started: Building and Running Clang. This page gives you the shortest path to checking out Clang and demos a few options. This should get you up and running with the minimum of muss and fuss.

LLVM Overview

The LLVM Project is a collection of modular and reusable compiler and toolchain technologies. Despite its name, LLVM has little to do with traditional virtual machines. The name "LLVM" itself is not an acronym; it is the full name of the project. LLVM began as a research project at the University of Illinois , with the goal of providing a modern, SSA-based compilation strategy capable of supporting both static and dynamic compilation of arbitrary programming languages. Since then, LLVM has grown to be an umbrella project consisting of a number of subprojects, many of which are being used in production by a wide variety of commercial and open source projects as well as being widely used in academic research . Code in the LLVM project is licensed under the "Apache 2.0 License with LLVM exceptions" The primary sub-projects of LLVM are:

*

The LLVM CORE libraries provide a modern source- and target-independent optimizer , along with code generation support for many popular CPUs (as well as some less common ones!) These libraries are built around a well specified code representation known as the LLVM intermediate representation ("LLVM IR"). The LLVM Core libraries are well documented , and it is particularly easy to invent your own language (or port an existing compiler) to use LLVM as an optimizer and code generator .

*

CLANG is an "LLVM native" C/C++/Objective-C compiler, which aims to deliver amazingly fast compiles, extremely useful error and warning messages and to provide a platform for building great source level tools. The Clang Static Analyzer

and clang-tidy

are tools that

automatically find bugs in your code, and are great examples of the sort of tools that can be built using the Clang frontend as a library to parse C/C++ code.

*

The LLDB project builds on libraries provided by LLVM and Clang to provide a great native debugger. It uses the Clang ASTs and expression parser, LLVM JIT, LLVM disassembler, etc so that it provides an experience that "just works". It is also blazing fast and much more memory efficient than GDB at loading symbols.

*

The LIBC++ and LIBC++ ABI projects provide a standard conformant and high-performance implementation of the C++ Standard Library, including full support for C++11 and C++14.

*

The COMPILER-RT project provides highly tuned implementations of the low-level code generator support routines like "__fixunsdfdi" and other calls generated when a target doesn't have a short sequence of native instructions to implement a core IR operation. It also provides implementations of run-time libraries for dynamic testing tools such as AddressSanitizer

, ThreadSanitizer

, MemorySanitizer

, and

DataFlowSanitizer .

*

The MLIR subproject is a novel approach to building reusable and extensible compiler infrastructure. MLIR aims to address software fragmentation, improve compilation for heterogeneous hardware, significantly reduce the cost of building domain specific compilers, and aid in connecting existing compilers together.

*

The OPENMP subproject provides an OpenMP runtime for use with the OpenMP implementation in

Clang.

*

The POLLY project implements a suite of cache-locality optimizations as well as auto-parallelism and vectorization using a polyhedral model.

*

The LIBCLC project aims to implement the OpenCL standard library.

*

The KLEE project implements a "symbolic virtual machine" which uses a theorem prover to try to evaluate all dynamic paths through a program in an effort to find bugs and to prove properties of functions. A major feature of klee is that it can produce a testcase in the event that it detects a bug.

*

The LLD project is a new linker. That is a drop-in replacement for system linkers and runs much faster. In addition to official subprojects of LLVM, there are a broad variety of other projects that use components of LLVM for various tasks . Through these external projects you can use LLVM to compile Ruby, Python, Haskell, Rust, D, PHP, Pure, Lua, and a number of other languages. A major strength of LLVM is its versatility, flexibility, and reusability, which is why it is being used for such a wide variety of different tasks: everything from doing light-weight JIT compiles of embedded languages like Lua to compiling Fortran code for massive super computers. As much as everything else, LLVM has a broad and friendly community of people who are interested in building great low-level tools. If you are interested in getting involved, a good first place is to skim the LLVM Blog and to sign up for the LLVM Developer

mailing list . For

information on how to send in a patch, get commit access, and copyright and license topics, please see the LLVM Developer Policy
