Default fusability check - used when the user doesn't pass in a callback.

Returns true if the `interiorPadding` of the `axis` is unknown.

What is a simple mappable operator? It: - Has a single tensor output - Output and all tensor inputs have the same shape - Output and all tensor input

Identifies operations that are beneficial to sink into kernels. These operations may not have side-effects, as otherwise sinking (and hence duplicatin

Returns true if the `startIndices` of the `axis` is unknown.

Returns true if the `stride` of the `axis` is unknown.

Check Op if it is a tensor Op.

workaround for issue intel/mkl-dnn#588

returns true if memory descriptor is zero */

Loads a global op at the current insertion point and returns the loaded value.

This function unrolls the given for-loop op and interleaves the instructions

SparseReshape implementation: Loop over input for (i = 0; i < input_indices.shape(0), ++i) { // multidim index to linear index linear_index = ...; /

Emitter for non-row-reduction kInput fusion pattern. Take a column reduction `memref<100x1100xf32> -> memref<1100xf32>` as an example: for (int iOutt

This function is copied from c10/util/tempfile.h, so it follows to these temperary directory env variables, too.

materialize shape computation IR by resolving tensor.dim + op having interface InferShapedTypeOpInterface: before ``` %arg0 = ... : tensor<?x10xf32> %
