mmh! That's because I have added the condition `!Features.hasComplexRangeOverride()` in `getPromotionType`. It is set to true, so it jumps to the next condition. There is override here, except that the value of the range is equal to the LangOpts if the value of the pragma is `DEFAULT`.   I guess I need to check that the value of the override is not equal to the Range of the LangOpt .... Not sure how to do that here.
