            Bug ID: 104423
           Summary: [libgomp, testsuite] Add means to do accelerator-only
                    testing in libgomp
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: vries at gcc dot gnu.org
  Target Milestone: ---

For nvptx offload testing, I switched to an eGPU setup, and cycle through 4
boards (kepler, maxwell, pascal, turing) to do pre-commit testing.  Sometim=
e in
the future that'll be 5, once I get an ampere board as well.

I run a script test-board.sh that iterates over various dimensions, which t=
akes
about 5 hours per board.  In practice, this means testing a patch get spread
over 2 days.

Furthermore, I'm looking to extend the dimensions on which I test, possibly
doubling the test-board time.

I noticed that a lot of time is spent running libgomp tests that do not use=
 the
accelerator, and which are not needed for my purposes.

It would be nice if libgomp provided a mode to run only tests that use the
accelerator, to drive down the test-board.sh execution time.=
