LLVM can accept the IR from the GNU Compiler Collection (GCC) toolchain, allowing it to be used with a wide array of extant compiler front-ends written for that project. LLVM can also be built with gcc after version 7.5. [37] LLVM can also generate relocatable machine code at compile-time or link-time or even binary machine code at runtime.
Like GCC, LLVM also targets some IRs meant for direct distribution, including Google's PNaCl IR and SPIR. A further development within LLVM is the use of Multi-Level Intermediate Representation with the potential to generate code for different heterogeneous targets, and to combine the outputs of different compilers.

It is usually implemented as a compiled language, and many vendors provide C++ compilers, including the Free Software Foundation, LLVM, Microsoft, Intel, Embarcadero, Oracle, and IBM. [ 14 ] C++ was designed with systems programming and embedded , resource-constrained software and large systems in mind, with performance , efficiency, and ...
LLVM bytecode: JavaScript: This allows running C/C++ codebases in a browser for example c2go [62] C: Go: Before the 1.5 release, the Go compiler was written in C. An automatic translator was developed to automatically convert the compiler codebase from C into Go.

Linaro is an engineering organization that works on free and open-source software such as the Linux kernel, the GNU Compiler Collection (GCC), QEMU, power management, graphics and multimedia interfaces for the ARM family of instruction sets and implementations thereof as well as for the Heterogeneous System Architecture (HSA). The company ...
The LLVM project originally intended to use GCC's front end. The GCC source code, however, is large and somewhat cumbersome; as one long-time GCC developer put it referring to LLVM, "Trying to make the hippo dance is not really a lot of fun". [17] Besides, Apple software uses Objective-C, which is a low priority for GCC developers.
Originally authored by Richard Stallman in 1987, GCC is a major modern compiler which is used to compile many free software projects, notably Linux. LLVM, formerly known as the Low Level Virtual Machine; Small-C by Ron Cain and James E Hendrix; Turbo Pascal, created by Anders Hejlsberg, first released in 1983. WATFOR, created at the University ...
