You need at least clang-9.0.0 (not yet released) to run some of these tests successfully, as they rely on Clang's support for BTF_KIND_VAR/BTF_KIND_DATASEC.
Can there be a runtime check for BTF that emits a skip instead of a fail in such a case?
I'm not sure how to do this simply and minimally intrusively. The best I can come up with is setting some envvar from Makefile and checking for that in each inidividual test, which honestly sounds a bit gross.
How hard is it for you guys to upgrade compiler used to run these test?
Thanks, Dan
