That name is a bit confusing, because this isn't the kind of "Virtual Machine" you get from VMWare or the like, but a way of representing programs for a non-existent, hence "virtual," computer architecture. It was created for use in compilers: you have a front-end that translates programming languages into the LLVM representation, and a back-end that generates object files for a specific processor and operating system. That means that to create compilers for X different languages to run on Y different platforms, you only need to write X front-ends and Y backends, rather than X*Y separate compilers. "cfe" is the "C front-end" which also handles C++ and the "Objective" variants of C and C++. https://en.wikipedia.org/wiki/LLVM The idea of having a well-defined intermediate representation for compilers and related tools has been around for nearly sixty years (https://en.wikipedia.org/wiki/CPL_(programming_language)) but LLVM seems to be the most successful implementation to date. -- John Dallman - Siemens Industry Software Limited is a limited company registered in England and Wales.

Folr LLVM : https://lmgtfy.com/?q=LLVM&pp=1 CFE stands for "C Front-End", a C family (C, C++, Objective C/C++, etc.) language front-end (https://clang.llvm.org/). It's part of the LLVM project. Chris Lattner's first email on cfe-dev (https://lists.llvm.org/pipermail/cfe-dev/2007-July/00.html) already calls it "clang", but "cfe" was the component name in Bugzilla, the mailing list name, and the directory in Subversion ( http://llvm.org/svn/llvm-project/cfe/trunk/ ).
