Hi,
PR68232 is a testsuite failure for targets with very low branch costs.
As the test is looking for if-conversion, it will fail for any subtarget
for which the cost of a branch is sufficiently low that if-conversion looks
more expensive.
In the current implementation this will be any subtarget with an unpredictable
branch cost of 0 or 1. I had thought this would be very few targets, but
at least powerpc64le and arm can trigger this for particular tuning targets.
This patch skips the test on those targets.
OK?
Thanks,
James

OK.
FWIW, I'd really like to see someone cleanly tweak config-list.mk so
that we can use it to test this kind of stuff.
In theory what I want to be able to do is build all the listed targets
and run a single test on them so that we can build these skip/xfail
lists much easier.
I've done it a few times by hand and it seems like it's something we
ought to be able to do much more easily.
