Someone here was asking about GCC, ISL, and tiling and we looked at the test gcc.dg/graphite/interchange-3.c on Aarch64. When this test is run the graphite pass output file contains the string 'not tiled' and since the dg-final scan-tree-dump is just looking for the string 'tiled', it matches and the test passes.
Is this intentional? It seems like if we wanted to check that it was not tiled we sould grep for 'not tiled', not just 'tiled'. If we want grep to see that it is tiled, then the check for tiling happening is wrong. Steve Ellcey sell...@marvell.com
