           Summary: [SSE] v4f64 = insert_subvector crash
           Product: new-bugs

            Status: NEW
          Severity: normal
          Priority: P

With top of tree, the attached gives the following crash when I run it through
llc.  I believe that this is a recent regression (within the last week), but
unfortunately my laptop is so slow that I probably won't be able to binary
search to find the change in a reasonable amount of time.  (I'll start off a
run to do that tonight, though.)

0x7ff159831310, 0x7ff159831e10 [ID=0]

Do not know how to split the result of this operator!
