ocr: ype Detinition Register optimizations Frequently used variables are placed into CPU registers to shorten the time if takes to access them. Additionally, the scope of variables IS analyzed to determine when registers can be reused. Call-stack overhead Parameters are passed into CPU registers elimination when possible rather than being pushed onto the stack. Common subexpression Repeated expressions. in complex mathe- elimination matical calculations are eliminated, so that no common subexpression runs more than once. This allows you to construct complex math algorithms that are easy to read, an ...
