User's Guide
The XL Fortran compiler helps you control the optimization of your
programs:
- You can select different levels of compiler optimizations.
- You can turn on separate optimizations for loops, floating point, and
other categories.
- You can optimize a program for a particular class of machines, or a very
specific machine configuration, depending on where the program will run.
Chapter 8. Optimizing XL Fortran Programs is a road map to these features.
