| // SME Register Operands |
| // There are three types of SME matrix register operands: |
| // * Tiles: |
| // |
| // These tiles make up the larger accumulator matrix. The tile representation |
| // has an element type suffix, e.g. za0.b or za15.q and can be any of the |
| // registers: |
| // ZAQ0..ZAQ15 |
| // ZAD0..ZAD7 |
| // ZAS0..ZAS3 |
| // ZAH0..ZAH1 |
| // or ZAB0 |
| // |
| // * Tile vectors: |
| // |
| // Their representation is similar to regular tiles, but they have an extra |
| // 'h' or 'v' to tell how the vector at [reg+offset] is layed out in the tile, |
| // horizontally or vertically. |
| // |
| // e.g. za1h.h or za15v.q, which corresponds to vectors in registers ZAH1 and |
| // ZAQ15, respectively. The horizontal/vertical is more a property of the |
| // instruction, than a property of the asm-operand itself, or its register. |
| // The distinction is required for the parsing/printing of the operand, |
| // as from a compiler's perspective, the whole tile is read/written. |
| // |
| // * Accumulator matrix: |
| // |
| // This is the entire matrix accumulator register ZA (<=> ZAB0), printed as |
| // 'za'. |
