[AArch64][SME] Introduce feature for streaming mode The Scalable Matrix Extension (SME) introduces a new execution mode called Streaming SVE mode. In streaming mode a substantial subset of the SVE and SVE2 instruction set is available, along with new outer product, load, store, extract and insert instructions that operate on the new architectural register state for the matrix. To support streaming mode this patch introduces a new subtarget feature +streaming-sve. If enabled, the subset of SVE(2) instructions are available. The existing behaviour for SVE(2) remains unchanged, the subset of instructions that are legal in streaming mode are enabled if either +sve[2] or +streaming-sve is specified. Instructions that are illegal in streaming mode remain predicated on +sve[2]. The SME target feature has been updated to imply +streaming-sve rather than +sve. The following changes are made to the SVE(2) tests: * For instructions that are legal in streaming mode: - added RUN line to verify +streaming-sve enables the instruction. - updated diagnostic to 'instruction requires: streaming-sve or sve'. * For instructions that are illegal in streaming-mode: - added RUN line to verify +streaming-sve does not enable the instruction. SVE(2) instructions that are legal in streaming mode have: if !HaveSVE[2]() && !HaveSME() then UNDEFINED; at the top of the pseudocode in the XML.
