No, these are a signal to target maintainers that they need
to decide whether to add support or accept the status quo
(in which case a new effective-target will be needed). See:
https://gcc.gnu.org/pipermail/gcc-patches/2020-October/557595.html:
The new tests are likely to fail on some targets with the sorry()
message, but I think target maintainers are best placed to decide
whether (a) that's a fundamental restriction of the target and the
tests should just be skipped or (b) the target needs to implement
the new hook.
Thanks,
