| Diagnostic Number | Diagnostic Description |
| Diagnostic 15304 | loop was not vectorized: non-vectorizable loop instance from multiversioning |
| Diagnostic 15541 | outer loop was not auto-vectorized: consider using SIMD directive |
| Diagnostic 15319 | loop was not vectorized: novector directive used |
| Diagnostic 15331 | xxxx was not vectorized: precis FP model implied by the command line or a directive prevents vectorization. Consider using fast FP model |
| Diagnostic 15335 | xxxx was not vectorized: vectorization possible but seems inefficient. Use vector always directive or -vec-threshold0 to override |
| Diagnostic 15344 | loop was not vectorized: vector dependence prevents vectorization xxxx |
| Diagnostic 15378 | xxxx was not vectorized: -ffreestanding flag prevents vectorization of integer divide/remainder |
| Diagnostic 15414 | loop was not vectorized: nothing to vectorize since xxxx body became empty after optimizations |
| Diagnostic 15517 | loops in this subroutine cannot be vectorized due to use of EBX/RBX register in inline ASM |
| Diagnostic 15521 | loop was not vectorized: simplify loop control flow and/or explicitly compute the trip count outside of the loop |
| Diagnostic 15523 | loop was not vectorized: cannot compute loop trip count outside of the loop |
| Diagnostic 15524 | xxxx was not vectorized: search loop cannot be vectorized unless all memory references can be aligned vector load |
| Diagnostic 15527 | loop was not vectorized: function call to xxxx cannot be vectorized |
| Diagnostic 15532 | xxxx was not vectorized: compile time constraints prevent loop optimization. Consider using -O3 loop was not vectorized: function call to xxxx cannot be vectorized |
| Diagnostic 15535 | xxxx was not vectorized: loop contains switch statement. Consider using if-else statement |
| Diagnostic 15537 | loop was not vectorized: implied FP exception model prevents usage of SVML library needed for truncation or integer divide/remainder. Consider changing compiler flags and/or directives in the source to enable fast FP model and to mask FP |
| Diagnostic 15542 | xxxx was not vectorized: inner loop was already vectorized |
| Diagnostic 15511 | Not enough parameters of vector variant 'xxxx' of function 'xxxx' at position <val> |
| Diagnostic 15509 | Extraneous parameter of vector variant 'xxxx' of function 'xxxx' at position <val> |
| Diagnostic 15513 | Incorrect type of mask parameter of vector variant 'xxxx' of function 'xxxx' at position <val> |
| Diagnostic 15487 | type converts: xxxx |
| Diagnostic 15479 | lightweight vector operations: xxxx |
| Diagnostic 15476 | scalar loop cost: xxxx |
