Detailed Description

For a memref with offset, sizes and strides, returns the offset, size, and potentially the size padded at the front to use for the linearized memref.

• If the linearization is done for emulating load/stores of element type with bitwidth srcBits using element type with bitwidth dstBits, the linearized offset and size are scaled down by dstBits/srcBits.
• If indices is provided, it represents the position in the original memref being accessed. The method then returns the index to use in the linearized memref. The linearized index is also scaled down by dstBits/srcBits. If indices is not provided 0, is returned for the linearized index.
• If the size of the load/store is smaller than the linearized memref load/store, the memory region emulated is larger than the actual memory region needed. intraDataOffset returns the element offset of the data relevant at the beginning.
