Tres Popp 81e8d778c4 Fix bug using std.rank instead of shape.rank

 2020-10-30 09:59:24 -07:00
Tres Popp 76b30fd426 Move unranked chlo lowering to transform_unranked_hlo. 
Additionally:
- Forward listeners through new if/else op builders.
This corrects an error that led to incomplete legalization of broadcasted op
lowering.
- Use OpConversionPattern to ensure up to date operand values are used.

Benjamin Kramer 3bf4277ea4 [MLIR] Add a lmhlo.reduce -> linalg.generic converter 
Doesn't support tensors right now, as it's somewhat hairy to support both at
the same time. Since we use a generic lowering the result is messy
and needs a mem2reg pass to eliminate extra load/store/allocas.

Smit Hinsu 6eda9ed273 Add compare_type optional attribute to CompareOp in HLO dialects 
If unspecified, `compare_type` is FLOAT for float element types, SIGNED for signed element types and UNSIGNED for unsigned element types. compare_type can be TOTALORDER for float element types.

- Added import and export support the attribute.
- Restricted legalization from HLO to TF to the default compare types.
- Updated existing usage of the CompareOp

A. Unique TensorFlower 33c450e4cb Fix the MHLO to LMHLO lowering of 'gather' 
The lowering assumes that the 'gather' op attributes are identical in both MHLO and LMHLO. But that's not true; some time ago the MHLO version was changed to pack 4 of its attributes into a struct. By doing the same for the LMHLO version we both fix the lowering for this op and resolve a longstanding TODO.

Stephan Herhut 2e30b59ddc Extend hlo-fuse-linalg slightly to support aliased returns. 
The fusion heuristic identifies the root of a fusion by checking whether an
output of a linalg operation is a function result. It did not consider outputs
flowing through aliasing operations (like casts).
