Public Attributes
unsigned	NumRows
	Number of rows of the matrix.
unsigned	NumColumns
	Number of columns of the matrix.
unsigned	NumInner

unsigned	TileSize = -1
	Number of rows/columns in a tile.
MatrixLoop	RowLoop
	The loop iterating on the rows.
MatrixLoop	ColumnLoop
	The loop iterating on the columns.
MatrixLoop	KLoop
	The loop iterating on k (inner dimension).

◆ CreateTiledLoops()

Creates an IR loop nests for tiling of the form below.

Returns the block for the inner loop body and sets {Column,Row,Inner}LoopHeader/Latch fields.

for ColumnLoop.Index = 0..NumColumns for RowLoop.Index = 0..NumRows for InnerLoop.Index = 0..NumInner
