The name LLVM originally stood for Low Level Virtual Machine. However, the project has since expanded, and the name is no longer an acronym but an orphan initialism. [7] LLVM is written in C++ and is designed for compile-time, link-time, runtime, and "idle-time" optimization.
Clang 1.0 released, with LLVM 2.6 for the first time. December 2009: Code generation for C and Objective-C reach production quality. Support for C++ and Objective-C++ still incomplete. Clang C++ can parse GCC 4.2 libstdc++ and generate working code for non-trivial programs, [21] and can compile itself. [37] 2 February 2010: Clang self-hosting ...
IBM® Open XL C/C++ 1.1 for z/OS® is the newest C/C++ compiler on z/OS that is fully based on the open source LLVM infrastructure. Open XL C/C++ 1.1 supports up to C17/C18 and C++17 language standard features and leverages the features of the IBM z16™ mainframe, ideal for z/OS UNIX System Services users porting applications from distributed ...
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 ...
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 ]
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 ...
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
