[PATCH] D54316: [RISCV] Add UNIMP instruction (32- and 16-bit forms)

[Alex Bradbury via Phabricator via llvm-commits]

asb added a comment.

I think this is fine, but c.unimp should be proposed on the RISC-V sw-dev mailing list or similar. As we discussed, it seems to make total sense to have this instruction (every other compressed instruction is nameable with c.something). But we should get community feedback first before merging in to LLVM. It's probably also worth highlighting the fact that "unimp" isn't actually guaranteed to trap according to the current RISC-V specs...
