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

[mlir] Fix the wrong computation of dynamic strides for lowering AllocOp to LLVM

2019-12-28T22:33:28+00:00

Leftover change from before the MLIR merge, reviewed at accepted at https://github.com/tensorflow/mlir/pull/338.

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

Adjust License.txt file to use the LLVM license

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. Closes tensorflow/mlir#226 PiperOrigin-RevId: 286803388

Added LLVM ops and lowering phases from standard dialect for FAbs, FCeil, Cos, FNeg, CopySign.

2019-12-18T19:42:43+00:00

Added test cases for the newly added LLVM operations and lowering features. Closes tensorflow/mlir#300 COPYBARA_INTEGRATE_REVIEW=https://github.com/tensorflow/mlir/pull/300 from dfki-jugr:std_to_llvm da6168bbc1a369ae2e99ad3881fdddd82f075dd4 PiperOrigin-RevId: 286231169

Introduce prefetch op: affine -> std -> llvm intrinsic

2019-12-18T18:00:04+00:00

Introduce affine.prefetch: op to prefetch using a multi-dimensional subscript on a memref; similar to affine.load but has no effect on semantics, but only on performance. Provide lowering through std.prefetch, llvm.prefetch and map to llvm's prefetch instrinsic. All attributes reflected through the lowering - locality hint, rw, and instr/data cache. affine.prefetch %0[%i, %j + 5], false, 3, true : memref<400x400xi32> Signed-off-by: Uday Bondhugula Closes tensorflow/mlir#225 COPYBARA_INTEGRATE_REVIEW=https://github.com/tensorflow/mlir/pull/225 from bondhugula:prefetch 4c3b4e93bc64d9a5719504e6d6e1657818a2ead0 PiperOrigin-RevId: 286212997

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

2019-12-18T17:29:20+00:00

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