[mir][Python][linalg] Support OpDSL extensions in C++.

Authored by gysit on May 7 2021, 8:14 AM.



The patch extends the yaml code generation to support the following new OpDSL constructs:

  • captures
  • constants
  • iteration index accesses
  • predefined types

I decided to add the following tests:

  • extended the existing OpDSL tests and added and to the python/dialect/linalg/opdsl folder
  • added a test to verify basic yaml codgen properties in test-linalg-ods-yaml-gen.yaml in the folder test/mlir-linalg-ods-gen
  • added a test for the fill_rng_2d operation in generalize-named-polymorphic-ops.mlir in the folder test/Dialect/linalg
  • added mini integration test in in the python/dialect/linalg/ folder

This has come along nicely since we looked at it together - thank you for spending the time on adding an additional layer of testing. Code lgtm - I'll leave to Nicolas wrt details of Linalg parse/print/etc.


In Python, one generally just says if self.ordered_capture_args and let the default empty-container-to-False rule apply.


Can be done in a follow-up, but I feel like this test is firmly in integration test territory and should probably be moved to the integration test directory.

Address review comment and rebase.

The dash (-) is used here to write the result to the standard output instead of writing to a file (hope this trick works on all platforms but mlir-linalg-ods-gen uses (-) as default file name so should be fine)


yes lets move this to a follow-up iteration

This revision does a little too much for my taste.
I don't want to burden you with splitting this in 4 independent CLs one per bullet point but in the future please heavily bias towards small independent CLs that are easy to just click.

Still, I think at least the captures should be separated out because it does increase the semantic power of linalg ops irrespective of opdsl.
It feels like there should be some roundtrip / invalid test, extensions to the structuredopinterface etc.
Or maybe I missing something that makes this simpler than what my gut feeling tells me?

In any case let's iterate Monday on VC.

I am unclear why this test is necessary, what does it cover that was not covered before ?

Activate and fix the yaml generation test.

This revision was automatically updated to reflect the committed changes.

I believe this change causes the assert on the attribute SmallVector (for size >256) to hit when the size isn't specified on Windows debug builds.
