GCL is an implementation of the Common Lisp language. It features the ability to compile to native object code and to load native object code modules directly into its lisp core. It also features a stratified garbage collection strategy, a source-level debugger and a built-in interface to the Tk widget system.

carp is a Lisp-like programming language that compiles to C. It features inferred static typing, macros, automatic memory management without a garbage collector, a REPL, and straightforward integration with code written in C.

ASDF is what Common Lisp hackers use to build and load software. It is the successor of the Lisp DEFSYSTEM of yore. ASDF stands for Another System Definition Facility.

Clozure CL (often called CCL for short) is a Common Lisp implementation featuring fast compilation speed, native threads, a precise, generational, compacting garbage collector, and a convenient foreign-function interface.

ECL is an implementation of the Common Lisp language as defined by the ANSI X3J13 specification. Its most relevant features are: a bytecode compiler and interpreter, being able to compile Common Lisp with any C/C++ compiler, being able to build standalone executables and libraries, and supporting ASDF, Sockets, Gray streams, MOP, and other useful components.

GNU CLISP is an implementation of ANSI Common Lisp. Common Lisp is a high-level, object-oriented functional programming language. CLISP includes an interpreter, a compiler, a debugger, and much more.

Lush is an object-oriented Lisp interpreter/compiler with features designed to please people who want to prototype large numerical applications. Lush includes an extensive library of vector/matrix/tensor manipulation, numerous numerical libraries (including GSL, LAPACK, and BLAS), a set of graphic functions, a simple GUI toolkit, and interfaces to various graphic and multimedia libraries such as OpenGL, SDL, Video4Linux, and ALSA (video/audio grabbing), and others. Lush is an ideal frontend script language for programming projects written in C or other languages. Lush also has libraries for Machine Learning, Neural Nets and statistical estimation.

Clasp is a new Common Lisp implementation that seamlessly interoperates with C++ libraries and programs using LLVM for compilation to native code. This allows Clasp to take advantage of a vast array of preexisting libraries and programs, such as out of the scientific computing ecosystem. Embedding them in a Common Lisp environment allows you to make use of rapid prototyping, incremental development, and other capabilities that make it a powerful language.

The "clang-runtime" library provides the implementations of run-time functions for C and C++ programs. It also provides header files that allow C and C++ source code to interface with the "sanitization" passes of the clang compiler. In LLVM this library is called "compiler-rt".

This package provides the run-time support library developed by the LLVM project for the OpenMP multi-theaded programming extension. This package notably provides libgomp.so, which is has a binary interface compatible with that of libgomp, the GNU Offloading and Multi Processing Library.

LLVM is a compiler infrastructure designed for compile-time, link-time, runtime, and idle-time optimization of programs from arbitrary programming languages. It currently supports compilation of C and C++ programs, using front-ends derived from GCC 4.0.1. A new front-end for the C family of languages is in development. The compiler infrastructure includes mirror sets of programming tools as well as libraries with equivalent functionality.

This package provides a complete Clang toolchain for C/C++ development to be installed in user profiles. This includes Clang, as well as libc (headers and binaries, plus debugging symbols in the debug output), and Binutils.

This package 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.

This package filters code through clang-format to fix its formatting. clang-format is a tool that formats C/C++/Obj-C code according to a set of style options, see https://clang.llvm.org/docs/ClangFormatStyleOptions.html.

This package contains the OCaml bindings distributed with LLVM.

Clang is a compiler front end for the C, C++, Objective-C and Objective-C++ programming languages. It uses LLVM as its back end. The Clang project includes the Clang front end, the Clang static analyzer, and several code analysis tools.

This is a linker wrapper for LLD; like ld-wrapper, it wraps the linker to add any missing -rpath flags, and to detect any misuse of libraries outside of the store.

LLD is a high-performance linker, built as a set of reusable components which highly leverage existing libraries in the larger LLVM Project.

Cling is an interactive C++17 standard compliant interpreter, built on top of LLVM and Clang. Cling can be used as a read-eval-print loop (REPL) to assist with rapid application development. Here's how to print "Hello World!" using cling:

cling '#include <stdio.h>' 'printf("Hello World!\n");'
