+Fine-grain dependences analysis
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+In addition of the ScopStmt-level depednences analysis, now the "polly-dependence"
+pass provides dependences analysis at memory reference level and memory access level.
+The memory reference level analysis distinguishes the accessed references in the
+same statement, and generates depednences relationships between (statement, reference)
+pairs. The memory acccess level analysis distinguishes accesses in the same statement,
+and generates depednences relationships between (statement, access) pairs. These
+fine-grain depednences are enabled by "-polly-dependences-analysis-level=reference-level"
+and "-polly-dependences-analysis-level=access-level", respectively.
