Hi all,
I reviewed this afternoon the postings from the gcc-testresults
mailing-list for the past month, and we have a couple of gfortran
testsuite failures showing up on various targets. Could people with
access to said targets (possibly maintainers) please file PRs in
bugzilla for each testcase, reporting the error message and/or
backtrace? (I'd be happy to be added to the Cc list of these)

This happens on all reported ia64 targets, including mine. What is
expected here? There is no vectorization on ia64, no reason for
peeling. The compilation has no problem, and there is no report
generated. As far as I know, the vectorization options are ignored.
Without unrolling, of course, gfortran doesn't optimize the loop at all,
but I assume that's a different question.
