How To Install llvm-4.0-examples on Ubuntu 18.04
Introduction
In this tutorial we learn how to install llvm-4.0-examples on Ubuntu 18.04.
What is llvm-4.0-examples
llvm-4.0-examples is:
LLVM is a collection of libraries and tools that make it easy to build compilers, optimizers, just-in-time code generators, and many other compiler-related programs.
LLVM uses a single, language-independent virtual instruction set both as an offline code representation (to communicate code between compiler phases and to run-time systems) and as the compiler internal representation (to analyze and transform programs). This persistent code representation allows a common set of sophisticated compiler techniques to be applied at compile-time, link-time, install-time, run-time, or “idle-time” (between program runs).
This package contains examples for using LLVM, both in developing extensions to LLVM and in using it to compile code.
