### Issue: Variable stride not recognized as non-contiguous `CGOpenMPRuntime.cpp` failed to detect `DeclRefExpr`, `MemberExpr`, `ArraySubscriptExpr` as non-contiguous. **Fixes**: `clang/lib/CodeGen/CGOpenMPRuntime.cpp` - Variable stride detection + dimension count logic Detect variable stride expressions (`DeclRefExpr/MemberExpr/ArraySubscriptExpr`) as non-contiguous Added testcases to cover stack arrays, heap pointers, struct members, etc., for expression semantics in non-contiguous update.
