[PATCH] D93298: [RISCV] add the MC layer support of Zfinx extension

[Jessica Clarke via Phabricator via cfe-commits]

jrtc27 added a comment.

The amount of duplication here really depresses me and is only going to get worse once codegen is added, but TableGen isn't able to have operands that use different register classes based on even HwMode, that I know of, and whilst you could make use of multi classes to generate both versions of the instructions you can't easily do that for patterns, so I don't know what the right answer is.
