2.13 General Optimization Tips

• Use the -v switch on the kf77 command line to view the switches the KAP preprocessor passes to the compiler and the linker.

• Use the -ipa switch to cause KAP to give information in the annotated listing about appropriate settings for the -ipall switch on a loop-by-loop basis.

• Avoid writing code that accesses an array outside of the array bounds, since this necessitates that you use the - assume=b switch. Setting -assume=b prevents KAP from performing many of its optimizations.
