[Bug tree-optimization/93017] FAIL: gcc.dg/graphite/interchange-1.c scan-tree-dump graphite "tiled"
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93017 --- Comment #5 from Romain Geissler --- Ah actually I see this on branch gcc 8 as well, with ISL 0.21. And apparently it is not making "make check" return an error code, so it's very possible that I had this error before without noticing it.

Some months ago with the same ISL version and branch gcc 9 I did not see such failures. Cheers, Romain

Most of the testcases really are "non-testcases", we do not do any transform there and the dump scans are simply spurious... The testcase in the summary already says it: /*FIXME: Between isl 0.12 and isl 0.15 the schedule optimizer needs to print something canonical so that it can be checked in the test. The final code generated by both are same in this case but the messaged printed are not consistent. */ and since there's a reduction involved in the testcase I _know_ we're not interchanging the loops. On x86_64 we actually dump "not tiled" (as I said, scanning for "tiled" is useless).

Scannig for 'tiled' is also borken since we either print "tiled" or "not tiled" ... What ISL version are you using?
