cris-elf too.  The "set the rtl costs correctly" comment assumes there's a
single linear cost metric shared by all gcc, not leading to pessimization
somewhere else.
We'll see about that.  IMHO, since you expected this to happen, a message with
a heads-up to target maintainers would have been nicer than just trapping a
test-case to silently fail; I had to search the (as always backlogged) mailing
lists to find the discussion (no URL, local mailbox).
