B.2.16 Standardized (STD)

• DO loop in the original program which had no executable statements was deleted. The source program contained a DO loop that contained no executable statements. The loop was deleted.

• DO loop was standardized by rerolling it. The DO loop indicated was recognized as an unrolled loop. The loop has been rerolled, that is, converted to an equivalent form in which the loop increment is one.

• IF and assignment were converted to an assignment using MAX or MIN. An IF with an associated assignment were converted into an assignment using an intrinsic function (either a MAX or a MIN).

• IF loop beginning here was transformed into a DO loop. An IF loop beginning at this statement was transformed into a DO loop. The DO variable increment statement was removed. Any references to the DO variable that followed the original increment have been advanced by 1 iteration.

• IF loop ending here was transformed into a DO loop. An IF loop ending at this statement was transformed into a DO loop. The branch back to the top of the loop was turned into a CONTINUE.

• IF statement that ensured the zero trip condition has been deleted. The output language has DO loops that are zero trip DO loops. The IF statement that appeared before this DO loop ensured that this DO loop was a zero trip DO loop, even if the Fortran variant had one trip DO loops. The IF statement has been deleted.

• Logical or arithmetic IF converted to block IF or single statement IF. A logical or arithmetic IF was changed to the corresponding block IF, and END IF and optional ELSE inserted, or to a single statement IF if appropriate.

• Two logical IFs converted to a single IF-THEN-ELSE block. Two logical or block IFs with complementary conditions (such as a.eq.0 and a.ne.0) were replaced by a single block IF WITH ELSE clause.
