B.2.10 Not Optimized (NO)

• Data dependence analysis aborted due to insufficient storage for graph arcs. Data dependence analysis was aborted because of insufficient storage allocated for dependence graph arcs.

• ELSE IF construct found. This loop was not optimized because the target machine does not support optimization of loops with ELSE IF constructs.

• Exits found. This loop was not optimized because it contains exits. The target machine does not support optimization of loops with exits.

• GOTO statement found. This loop was not optimized because the target machine does not support optimization of loops with GOTO statements.

• Inner loop structure is too complex. This loop was not optimized because the inner loop structure was too complex. This could be because of a complex data dependence graph or because of a complex flow graph structure.

• Loop was asserted serial by directive. The present loop was asserted serial by the use of a directive. Optimization was not attempted for this loop.

• Nested IFs found. This loop was not optimized because the target machine does not support optimization of loops with nested IFs.

• No optimizable statements found. No optimizable statements were found in this loop.

• No parallelism detected. The optimizer could not detect any parallelism in this loop.

• Non-integer loop control variable found. This loop was not optimized because of a non-integer loop control variable. Changing the index variable appropriately may enable optimization of the loop.

• Non-optimizable intrinsic found. This loop was not optimized because it contains a call to a nonoptimizable intrinsic function or subroutine.

• Non-optimizable operator found. This loop was not optimized because it contains an operator that cannot be optimized.

• Non-optimizable statement found. This loop was not optimized because it contains one or more statements that cannot be optimized safely.

• Non-optimizable variable type found. This loop was not optimized because of the presence of a nonoptimizable variable type. The target machine does not support optimizations for variables of this type.

• Non-stride-1 references found. This loop was not optimized because the target machine does not support optimization of non-stride-1 loops.

• Not an inner loop. This loop was not optimized because the target machine does not support the optimization of noninner loops.

• Optimization was disabled. The present loop was not optimized because optimization had been disabled.

• Prevented by reference(s) to variable "#1". This loop was not optimized because of the presence of the named variable. Restructuring of the code to simplify references to this variable may enable further optimization.

• Scalar mode determined best. No better execution mode than scalar was found for this loop. Of all valid loop orderings considered, this ordering was determined to be the best.

• Statement with alternate returns found. This loop was not optimized because of the presence of a statement with alternate returns.

• Too many dependence arcs. There are too many dependence arcs for this loop. Increasing the value of - arclimit may enable optimization of this loop.

• Too many loop orderings. There are too many loop orderings generated for this loop nest. Increasing the value of -limit may enable optimization of this loop.

• Unoptimizable call to "#1" found. This loop was not optimized because of the presence of a call to the given function or subroutine. Inline expansion or IPA would be necessary for optimization to be performed safely.

• Unoptimizable input or output statements found. This loop was not optimized because it contains unoptimizable input or output statements.
