[MLIR] Break cyclic dependencies with MLIRAnalysis
ClosedPublic

Authored by stephenneuendorffer on Jan 29 2020, 11:37 AM.

Details

Summary

MLIRAnalysis depended on MLIRVectorOps
MLIRVectorOps depended on MLIRAnalysis for Loop information.

Both of these can be solved by factoring out libraries related to loop
analysis into their own library. The new MLIRLoopAnalysis might be
better off with the Loop Dialect in the future.

LGTM, thanks!

But I'd like to have River's review here first.

I have a local patch prototyping this as well, but I split this in two libraries because it seemed a bit strange to me that using "Dominance" would require me to ask for linking to libVerifier (I'm not opposed this though).

I think we can break the dependency by removing all of the "test" passes that are currently in the Analysis lib. They predate the Test dialect, and should really be moved out.

OpStats.cpp and MemRefBoundCheck.cpp also depend on the MLIRPassLibrary. What do you want to do with these?

OpStats.cpp can be moved to Transforms for now, and MemRefBoundCheck is just a test pass so it can go into the test/lib/Transforms.

I suspect a bunch of this will end-up moving to the Affine dialect itself.
