            Bug ID: 66621
           Summary: [4.9/5/6 Regression] Mistakenly unsupported tests in
                    g++.dg/torture/
           Product: gcc
           Version: 5.1.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jakub at gcc dot gnu.org

  Target Milestone: ---

I've noticed that since r208416 a lot of g++.dg/torture/* tests use
{ target c++11 } which makes all of them UNSUPPORTED, because g++.dg/torture/
does not cycle through c++98/c++11/c++14 options.

grep
'\(vshuf.*\|pr\(40991\|47559\|49770\|51598\|53161\|53602\|55260-1\|56768\|59295\)\)\.C'
g++.sum  | grep -v ^UNSUPPORTED | wc -l
0

Thus, either all those tests should be changed back to use e.g. // {
dg-additional-options "-std=c++11" }
or g++.dg/torture/ needs to cycle through the options too.
