[mlir] Update the CallGraph for nested symbol references, and simplify CallableOpInterface

2020-01-13T23:51:28+00:00

Summary: This enables tracking calls that cross symbol table boundaries. It also simplifies some of the implementation details of CallableOpInterface, i.e. there can only be one region within the callable operation. Depends On D72042 Reviewed By: jpienaar Differential Revision: https://reviews.llvm.org/D72043

[mlir] Remove unnecessary assert for single region.

This was left over debugging.

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

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.

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.

Add a couple useful LLVM_DEBUG's to the inliner.

This makes it easier to narrow down on ops that are preventing inlining. PiperOrigin-RevId: 286243868

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
