Intermediate representations is a fundamental concept within compiler design and program analysis, referring to abstract, structured representations of program code positioned between the source language and the target machine code. This conceptual paradigm investigates methods for transforming and analyzing programs in a form optimized for tasks such as code optimization, translation across different target architectures to achieve portability, and various forms of static and dynamic program analysis, often exhibiting characteristics of being less platform-dependent than machine code and more amenable to manipulation than source code.
