Enumerators
| Name | Value | Comment |
|---|---|---|
| TM_Unspecified | 0 | The pass can use heuristics to determine whether a transformation should be applied. |
| TM_Enable | 1 | The transformation should be applied without considering a cost model. |
| TM_Disable | 2 | The transformation should not be applied. |
| TM_Force | 4 | Force is a flag and should not be used alone. |
| TM_ForcedByUser | 5 | The transformation was directed by the user, e.g. by a #pragma in the source code. If the transformation could not be applied, a warning should be emitted. |
| TM_SuppressedByUser | 6 | The transformation must not be applied. For instance, `#pragma clang loop unroll(disable)` explicitly forbids any unrolling to take place. Unlike general loop metadata, it must not be dropped. Most passes should not behave differently under TM_Disable and TM_SuppressedByUser. |
