ConstToAttrStridedSliceFusion

Description

Fuses the StridedSlice operator into the StridedSliceD operator, and converts StridedSlice's Const node inputs (begin, end, and strides) into attributes of StridedSliceD.

Restrictions

• This fusion pattern does not take effect when the scenario involves dynamic shapes and the StridedSlice operator is supported on the corresponding platform.
• The fusion pattern does not take effect when the output shape contains 0.
• The fusion pattern does not take effect when the begin, end, and strides inputs of StridedSlice are not Const nodes.
• The fusion pattern does not take effect when the StridedSliceD operator is not supported on the platform.
• The fusion pattern does not take effect when the last axis of strides is less than 1.
• The fusion pattern does not take effect when any one of the attributes new_axis_mask, shrink_axis_mask, begin_mask, end_mask, and ellipsis_mask is missing.
• The fusion pattern does not take effect when begin_mask is 0 and all other attributes are not 0.
• The fusion pattern does not take effect when the data type is not supported by the fused operator.
