Optimizations

The Compiler applies a variety of code improving techniques commonly defined as optimizations. This section gives a short overview of the most important optimizations, the topics covered are as follows:

• Lazy Instruction Selection
  
  
• Strength Reduction
  
  
• Shift Optimizations
  
  
• Accessing Bitfields
  
  
• HC08 Branch Optimizations
  
  
• Optimization for Execution Time or Code Size
