llvm dev - Sep 2019 - MCJIT on cross-toolchain?

I apologize in advance if this is a somewhat silly question (I’m making my first
steps in the infrastructure), but still.

Is it true that if an LLVM toolchain is compiled as a cross-toolchain, MCJIT is
not expected to work?
I’m still working on a toolchain that cross-compiles from Windows to ARM Linux,
and I’ve managed to get clang and lld tests to pass, but some (not all) MCJIT
tests are failing.

If the answer is yes, what would be the appropriate way to skip those tests?

Sergej.

Correction: I’m talking about unit tests. They fail with access violation
following the message "'skylake' is not a recognized processor for
this target (ignoring processor)”.

I think the answer is: These tests are buggy & should be fixed. They should
be "not run" if the native target isn't compiled in but is needed
for a
test.

Right - I think 'lit' tests have a way to say "REQUIRES:
native-target" or
something and perhaps the unit tests haven't had the equivalent thing done
to them. (it'd probably be programmatic in the unit tests - calling some
LLVM API to see if the native target is available, then bailing
out/skipping the test functionality entirely if it isn't).
