Detailed Description

An interface for operations that use Arm SME tiles.

These operations need to be assigned a tile ID, an i32 attribute, which specifies which virtual tile within the ZA storage to use. The number of tiles available depends on the type of the tile. This is summarized below:

Tile Vector Types	Possible Tile IDs
vector<[16]x[16]xi8>	0
vector<[8]x[8]xi16>, vector<[8]x[8]xf16>, or vector<[8]x[8]xbf16>	0 and 1
vector<[4]x[4]xi32> or vector<[4]x[4]xf32>	0 to 3 (inclusive)
vector<[2]x[2]xi64> or vector<[2]x[2]xf64>	0 to 7 (inclusive)
vector<[1]x[1]xi128>	0 to 15 (inclusive)
