danix800 updated this revision to Diff 553335.
danix800 edited the summary of this revision.
danix800 added a comment.
1. `getDynamicExtent()` can return both signed/unsigned results. They are
converted to signed version as `ArrayIndexType` to keep consistency. All other
APIs return this version
(even for static type size). Testcases are not affected. `ArrayBoundV2` doesn't
need explicit `unsigned`-to-`signed` casts to avoid `signed<->unsigned`
comparison;
2. `getElementExtent()` could be 0, add more defensive checking;
3. `MPIChecker` added more defensive checking, e.g: `ElementCount` doesn't have
to be `ConcreteInt` so avoid direct
`ElementCount.castAs<nonloc::ConcreteInt>()`.
