1097execPartial or unexisting vectorization - Use pragma to force vectorization and check potential dependencies between array access.11411.5194.2598.28
[SA] Presence of expensive FP instructions - Perform hoisting, change algorithm, use SVML or proper numerical library or perform value profiling (count the number of distinct input values). There are 28 issues (= instructions) costing 4 points each.112
[SA] Inefficient vectorization: use of shorter than available vector length - Force compiler to use proper vector length. CAUTION: use of 512 bits vectors could be more expensive than 256 bits on some processors. Use intrinsics (costly and not portable). The issue costs 2 points.2
Warning! There is no dynamic data for this loop. Some checks can not been performed.0
576execPartial or unexisting vectorization - Use pragma to force vectorization and check potential dependencies between array access.211.3638.8933.33
[SA] Several paths (2 paths) - Simplify control structure or force the compiler to use masked instructions. There are 2 issues ( = paths) costing 1 point each.2

[SA] Presence of expensive FP instructions - Perform hoisting, change algorithm, use SVML or proper numerical library or perform value profiling (count the number of distinct input values). There are 8 issues (= instructions) costing 4 points each.32
[SA] Less than 10% of the FP ADD/SUB/MUL arithmetic operations are performed using FMA - Reorganize arithmetic expressions to exhibit potential for FMA. This issue costs 4 points.4

523execPartial or unexisting vectorization - Use pragma to force vectorization and check potential dependencies between array access.10006.08020
[SA] Too many paths (at least 1000 paths) - Simplify control structure. There are at least 1000 issues ( = paths) costing 1 point.1000
Warning! Some static analysis are missing because the loop has too many paths. Use a higher value for --maximal_path_number option.0
