[PATCH] D17905: [Polly][DOC] Add fine-grain dependences analysis to release notes.

[Hongbin Zheng via llvm-commits]

etherzhhb created this revision.
etherzhhb added reviewers: grosser, jdoerfert, Meinersbur.
etherzhhb added a subscriber: Polly.
etherzhhb added a project: Polly.

Later I will try to add the document about how to extract LLVM IR based dependences result from the fine-grain dependences analysis.

+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.
