Modern and emerging architectures demand increasingly complex compiler analyses
and transformations. As the emphasis on compiler infrastructure moves beyond
support for peephole optimizations and the extraction of instruction-level
parallelism, they should support custom tools designed to meet these demands
with higher-level analysis-powered abstractions and functionalities of wider
program scope. This paper introduces NOELLE, a robust open-source
domain-independent compilation layer built upon LLVM providing this support.
NOELLE extends abstractions and functionalities provided by LLVM enabling
advanced, program-wide code analyses and transformations.This paper shows the
power of NOELLE by presenting a diverse set of 11 custom tools built upon it.
