GAP Message (Diagnostic ID 30532)

NOTE:
This feature is only available for ifort.

Message

Store the value of the upper-bound expression (%s) of the loop at line %d into a temporary local variable, and use this variable as the new upper-bound expression of the loop. To do this, insert a statement of the form "temp = %s" right before the loop, where "temp" is the newly created local variable. Choose a variable name that is unique, then replace the loop's original upper-bound expression with "temp".

Advice

Use a local-variable for the loop upper-bound if the upper-bound does not change during the execution of the loop. This enables the compiler to recognize the loop as a proper counted do loop, which in turn enables various loop optimizations including vectorization and parallelization.

This message appears when the compiler can output the exact upper-bound variable to be replaced.

Verify

Confirm that the value of the upper-bound expression does not change throughout the entire execution of the loop.
