LLVM, also called LLVM Core, is a target-independent optimizer and code generator. [5] It can be used to develop a frontend for any programming language and a backend for any instruction set architecture.
The Swift community maintains a version which adds support for the language. Free Pascal and the Lazarus IDE can use LLDB as backend for their own FpDebug engine. The LLDB debugger is known to work on macOS , Linux , FreeBSD , NetBSD and Windows , [ 4 ] and supports i386 , x86-64 , and ARM instruction sets . [ 5 ]
As with LLVM, it is free and open-source software under the Apache 2.0 software license. [5] [6] Its contributors include Apple, Microsoft, Google, ARM, Sony, Intel, and AMD. Clang 17, the latest major version of Clang as of October 2023, has full support for all published C++ standards up to C++17, implements most features of C++20, and has ...
ROSE: an open source compiler framework to generate source-to-source analyzers and translators for C/C++ and Fortran, developed at Lawrence Livermore National Laboratory MILEPOST GCC : interactive plugin-based open-source research compiler that combines the strength of GCC and the flexibility of the common Interactive Compilation Interface that ...
Apple first shipped LLVM-based technology in the 10.5 (and 10.4.8) OpenGL stack as a just-in-time (JIT) compiler, shipped the llvm-gcc compiler in the integrated development environment (IDE) Xcode 3.1, Clang 1.0 in Xcode 3.2, Clang 2.0 (with C++ support) in Xcode 4.0, and LLDB, libc++, assemblers, and disassembler technology in later releases.
y := 1 y := 2 x := y Humans can see that the first assignment is not necessary, and that the value of y being used in the third line comes from the second assignment of y. A program would have to perform reaching definition analysis to determine this. But if the program is in SSA form, both of these are immediate: y 1 := 1 y 2 := 2 x 1 := y 2
The AMD Optimizing C/C++ Compiler (AOCC) is an optimizing C/C++ and Fortran compiler suite from AMD targeting 32-bit and 64-bit Linux platforms. [1] [2] It is a proprietary fork of LLVM + Clang with various additional patches to improve performance for AMD's Zen microarchitecture in Epyc, and Ryzen microprocessors.
Emscripten is an LLVM/Clang-based compiler that compiles C and C++ source code to WebAssembly, [4] primarily for execution in web browsers. Emscripten allows applications and libraries written in C or C++ to be compiled ahead of time and run efficiently in web browsers, typically at speeds comparable to or faster than interpreted or dynamically ...
