I am currently trying to set up new performance and regression testers for Polly and LLVM and would like to XFAIL two test cases. I am using the LNTBuilder instead of the NightlyTestBuilder out of the assumption
that the LNTBuilder is the more modern solution.
However, when trying to xfail test cases I realized the xfail= parameter of getLNTFactor is ignored. Previously this was not an issue,
as LNT would automatically XFAIL test cases that failed in the previous run, but it seems Daniel removed this 'feature' a year ago:

lnt runtest: Don't use XFAIL just because a test was previously failing.
Does anyone know what is the canonical way to mark xfailures when running nightly tests on the buildbots?
Should I switch to the NightlyTestBuilder? Or is there a way to convince the LNTBuilder to accept XFAILures e.g. by allowing
the LitTestCommand to take an optional xfails argument according
to which test results will be relabeled for the buildbot?
