Looking at one of the assembly generated vmov is indeed not there:

------- Comment #3 from jules at gcc dot gnu dot org 2009-03-11 20:47 -------
These failures show up because the tests are kind of weak. There's no
particular reason that vget_low* intrinsics should generate vmov instructions
as the tests are expecting: the assembly output shown with vldr/fstd works just
as well, and no instructions at all (i.e. just a hint to the register
allocator) would work even better.
Without converting all the Neon intrinsic tests to be execution rather than
compilation tests, I'm not sure if there's any way they can be made robust.

That's the move intrinsic tests. I think polytypes.c is because of
additional diagnostics added at some point for which target-independent
tests were updated but not all target-specific tests (i.e., the testcase
needs updating for the current front-end diagnostics). Unlike the move
instrinsics tests polytypes.c is not an automatically generated file, so
should be straightforward for anyone to fix.

If it's too hard to make the test work reliably, may be just XFAIL them or
deactivate them until someone comes up with a more reliable way?
