--- Comment #1 from Jeffrey A. Law <law at gcc dot gnu.org> ---
Yes, the xiangshan-nanhu scheduler model needs some serious work. The generic
RISC-V code will trigger an ICE if there's an insn in the stream that does not
map to a functional unit in the uarch's scheduler description.
I've asked the submitter of the xiangshan-nanhu port to fix this, but haven't
heard from them since immediately after the request. Given the lack of
response we should probably seriously consider disabling its scheduler
description until such time as it's been updated.
