With the increasing popularity of embedded systems, the interest in evaluating and optimizing non-functional properties like execution time and energy of these systems is increasing. In this paper, we describe a Resource-usage Estimate Expression Language (REEL), which allows the user to argue about these properties, within the source code, in a compiler understandable manner. Furthermore, we discuss the integration of REEL within a compiler framework. We also show the propagation of REEL annotations within the compiler, and how they can be exploited to make decisions based on the non-functional properties within the source code. Finally, we explore REEL's potential to perform ILP-based optimizations.enhttps://creativecommons.org/licenses/by/4.0/CompilationAnnotationsNon-functional PropertiesFunction InliningTechnikResearch Report10.15480/882.254510.15480/882.2545Other
