MVE has a basic symmetry between it's normal loads/store operations and the masked variants. This means that masked loads and stores can use pre-inc and post-inc addressing modes, just like the standard loads and stores already do. To enable that, this patch adds all the relevant infrastructure for treating masked loads/stores addressing modes in the same way as normal loads/stores. This involves: - Adding an AddressingMode to MaskedLoadStoreSDNode, along with an extra Offset operand that is added after the PtrBase. - Extending the IndexedModeActions from 8bits to 16bits to store the legality of masked operations as well as normal ones. This array is fairly small, so doubling the size still won't make it very large. Offset masked loads can then be controlled with setIndexedMaskedLoadAction, similar to standard loads. - The same methods that combine to indexed loads, such as CombineToPostIndexedLoadStore, are adjusted to handle masked loads in the same way. - The ARM backend is then adjusted to make use of these indexed masked loads/stores. - The X86 backend is adjusted to hopefully be no functional changes.
