So, this has sat for a while and it’s getting close to the end of stage1 now. I
don’t see that we're any closer to a solution that allows us to use POImode
without risking this ICE. I had to disable the use of VSX vector pair
loads/stores in inline expansion of memcpy/memmove do avoid it.

So, would it be legitimate for extract_low_bits to query if the truncate
pattern it will likely use is actually available?

If it feels like a hack, that would because it is a hack.
What I’d really like to discuss is how to accomplish the real goal: keep
anything from trying to do other operations (zero/sign extend for one) to
POImode.
Is there an existing mechanism for this?

Now that the documentation for partial modes says they have a known
number of bits of precision, would it make sense for extract_low_bits to
check this before attempting to extract the bits?
This would solve the problem we have been having with POImode and
extract_low_bits -- DSE tries to use it t
