Intermediate Optimizations

After it translates a program's source code into its intermediate representation, the compiler optionally applies optimizations that reduce the program's size, improve its execution speed, or both. The topics in this chapter explains these optimizations and how to apply them:

• Interprocedural Analysis
  Interprocedural analysis examines the flow of execution and data within entire files and programs to improve performance and reduce size.
• Intermediate Optimizations
  After it translates a function into its intermediate representation, the compiler may optionally apply some optimizations. The result of these optimizations on the intermediate representation will either reduce the size of the executable code, improve the executable code's execution speed, or both.
• Inlining
  Inlining replaces instructions that call a function and return from it with the actual instructions of the function being called.
