A upside-down approach to GCC optimizations

Many traditional optimizations in the compiler work from a top-down approach, which starts at the beginning of the program and works toward the bottom. This allows the optimization to see the definition of something before any uses of it, which simplifies most evaluations. It’s also the natural way we process things. In this article, we’ll […] The post A upside-down approach to GCC optimizations appeared first on Red Hat Developer....
