LLVM intermediate representation (IR) is the abstract description machine operations used to translate LLVM front ends to a form that's executable by a target machine. Optimizations and transformations are performed on the IR by the LLVM library to create executable images. This tutorial will introduce the IR syntax, describe basic tools for manipulating IR formats, and describe mappings of IR from various common source code control structures. Tutorial materials with specific examples will be made available for the tutorial presentation, and for offline review.
