(Without trying it I assume it also fails on s390). -- snip -- FAIL: gfortran.dg/pr69987.f90 -O (test for excess errors) Excess errors: f951: Warning: -fprefetch-loop-arrays not supported for this target (try -march switches) -- snip --

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69987 Jeffrey A. Law changed: What|Removed |Added Status|NEW |RESOLVED CC||law at redhat dot com Resolution|--- |DUPLICATE --- Comment #3 from Jeffrey A. Law --- Essentially a duplicate of 69989, loop optimizer deletes an edge in an irreducible region, we schedule loop fixups, and we hit an explicit call to verify_loop_structure before fixing up the loops. This one hits from a different part of the loop optimizer, but it's essentially the same bug as 69989. *** This bug has been marked as a duplicate of bug 69989 ***
