Hi Tom, hello all,

it turned out that the testcase fails on PowerPC (but not x86_64)
as the nvptx lto complains: unresolved symbol __sync_val_compare_and_swap_16

The testcase uses int128 – and that's the culprit, but I have no idea
why it only fails with PowerPC and not with x86-64.

Unless someone sees a good way to implement __sync_val_compare_and_swap_16,
I propose to XFAIL it for now.

Namely: Split-off the int128 testcase into a new file and run it only
if not nvptx-offloading on PowerPC. If on nvptx+PowerPC, link that testcase
as well – but XFAIL it.

OK? Or do you/does anyone have a better idea?

Tobias

PS: Should I open a PR for the missing __sync_val_compare_and_swap_16?
