[mlir] NFC: Rename index_t to index_type

2020-03-06T13:36:11+00:00

mlir currently fails to build on Solaris: /vol/llvm/src/llvm-project/dist/mlir/lib/Conversion/VectorToLoops/ConvertVectorToLoops.cpp:78:20: error: reference to 'index_t' is ambiguous IndexHandle zero(index_t(0)), one(index_t(1)); ^ /usr/include/sys/types.h:103:16: note: candidate found by name lookup is 'index_t' typedef short index_t; ^ /vol/llvm/src/llvm-project/dist/mlir/include/mlir/EDSC/Builders.h:27:8: note: candidate found by name lookup is 'mlir::edsc::index_t' struct index_t { ^ and many more. Given that POSIX reserves all identifiers ending in `_t` 2.2.2 The Name Space , it seems quite unwise to use such identifiers in user code, even more so without a distinguished prefix. The following patch fixes this by renaming `index_t` to `index_type`. cases. Tested on `amd64-pc-solaris2.11` and `sparcv9-sun-solaris2.11`.

[mlir] NFC: Remove Value::operator* and Value::operator-> now that Value is properly value-typed.

2020-01-11T16:54:39+00:00

Summary: These were temporary methods used to simplify the transition. Reviewed By: antiagainst Differential Revision: https://reviews.llvm.org/D72548

NFC: Replace ValuePtr with Value and remove it now that Value is value-typed.

2019-12-24T00:36:53+00:00

ValuePtr was a temporary typedef during the transition to a value-typed Value. PiperOrigin-RevId: 286945714

NFC: Introduce new ValuePtr/ValueRef typedefs to simplify the transition to Value being value-typed.

2019-12-23T06:00:23+00:00

This is an initial step to refactoring the representation of OpResult as proposed in: https://groups.google.com/a/tensorflow.org/g/mlir/c/XXzzKhqqF_0/m/v6bKb08WCgAJ This change will make it much simpler to incrementally transition all of the existing code to use value-typed semantics.

Add integer bit-shift operations to the standard dialect.

2019-12-22T18:02:13+00:00

Rename the 'shlis' operation in the standard dialect to 'shift_left'. Add tests for this operation (these have been missing so far) and add a lowering to the 'shl' operation in the LLVM dialect. Add also 'shift_right_signed' (lowered to LLVM's 'ashr') and 'shift_right_unsigned' (lowered to 'lshr'). The original plan was to name these operations 'shift.left', 'shift.right.signed' and 'shift.right.unsigned'. This works if the operations are prefixed with 'std.' in MLIR assembly. Unfortunately during import the short form is ambigous with operations from a hypothetical 'shift' dialect. The best solution seems to omit dots in standard operations for now.

NFC: Remove unnecessary 'llvm::' prefix from uses of llvm symbols declared in `mlir` namespace.

Aside from being cleaner, this also makes the codebase more consistent. PiperOrigin-RevId: 286206974

Add a layer of EDSC for linalg.GenericOp

2019-12-14T00:57:57+00:00

This will be evolved into a simple programming model for custom ops and custom layers in followup CLs. This CL also deletes the obsolete tablegen's reference-impl.td that was using EDSCs. PiperOrigin-RevId: 285459545

Refactor dependencies to expose Vector transformations as patterns - NFC

2019-12-04T01:52:10+00:00

This CL refactors some of the MLIR vector dependencies to allow decoupling VectorOps, vector analysis, vector transformations and vector conversions from each other. This makes the system more modular and allows extracting VectorToVector into VectorTransforms that do not depend on vector conversions. This refactoring exhibited a bunch of cyclic library dependencies that have been cleaned up. PiperOrigin-RevId: 283660308
