This looks reasonable to me, based on the discussions in the lang meeting. We can always un-gate any of these targets in the future, when a maintainer of the target takes a close look and makes sure the tests pass. I think it might be useful to point people to an invocation of r=me with such a comment added next to the match arm for the unstable targets. (Not next to the match arm for RISC-V ILP32E, that one is unstable for a different reason.) @bors delegate+ |
