testsuite: T21710a fails on PowerPC

Summary

T21710a fails on PowerPC without output.

Steps to reproduce

Run test T21710a

Expected behavior

The test passes or is skipped.

Environment

• GHC version used: HEAD
• Operating System: openSUSE Leap 15.2
• System Architecture: powerpc64le

added broken test needs triage testsuite labels

Note: powerpc64le does not implement tables next to code. That will lead to different Cmm, which might be the cause of the failure we are seeing here.

It sounds like the test script might need to be updated:

test('T21710a', [ only_ways(['optasm']), when(wordsize(32), skip), grep_errmsg('(call)',[1]) ], compile, ['-ddump-cmm -dno-typeable-binds'])

assigned to @AndreasK

added Pnormal PowerPC Ttask labels and removed needs triage label

Could you post the Cmm code for this test on ppc? Hard to say how it fails otherwise. It being due to TNTC sounds plausible though.

changed milestone to %9.6.1

I am reopening because this still fails on PowerPC. I could not find a CI run where no TNTC was actually tested. It is a manual job.

See failure on Power in my fork.

T21710a is still run on x86_64 without TNTC, see a recent nightly job.

Thanks for the ping. It seems I didn't fully implement the hadrian change hopefully !9384 (closed) will fix that.

Should be fixed now because of !9384 (closed), please reopen if not.
