;) I _think_ the testcases got annotated with "tiled" a lot and really meant to test whether tiling would be possible (interchange tests should check for interchange only). I think this is probably not intentional but unless you want extra FAILs I suggest to leave this alone... Richard. > Steve Ellcey > sell...@marvell.com >
