            Bug ID: 66005
           Summary: libgomp make check time is excessive
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libgomp
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
                CC: jakub at gcc dot gnu.org, tschwinge at gcc dot gnu.org
  Target Milestone: ---

With all those OpenACC tests having been added to the libgomp testsuite, make
check times have skyrocketed on the gcc 5 branch and mainline:

On a reasonably fast x86 machine, it takes 4286 seconds:

Test Run By ro on Sat May  2 00:56:49 2015
runtest completed at Sat May  2 02:08:15 2015

while e.g. on slower sparc boxes we're at 29406 seconds:

Test Run By ro on Fri May  1 18:38:07 2015
runtest completed at Sat May  2 02:48:13 2015

while for 4.9 we had only 7825 seconds:

Test Run By ro on Sat May  2 17:20:23 2015
runtest completed at Sat May  2 19:30:48 2015

Being sequential, the libgomp testsuite is the last to finish, slowing down the
whole test.
