Chapter 5 Loop and cross-module optimization features

This chapter discusses loop optimization features available with the
HP-UX compilers, including those inherent in optimization level +O3. This includes a discussion of the following topics:

“Strip mining”
“Inlining within a single source file”
“Cloning within a single source file”
“Data localization”
“Loop blocking”
“Loop distribution”
“Loop fusion”
“Loop interchange”
“Loop unroll and jam”
“Preventing loop reordering”
“Test promotion”
“Cross-module cloning”

For more information as to specific loop optimization command-line options, as well as related pragmas and directives for optimization, please see "Chapter 7 “Controlling optimization”.
