[PATCH] D113237: [RISCV] Support Zifencei extension

[Kito Cheng via Phabricator via llvm-commits]

kito-cheng added a comment.

I think this makes us need to consider another issue: Should we support `I` extension with version `2.1`? zifencei and zicsr split from `I` ext. since `2.1`.

RISC-V GNU toolchain site are consider to bump the extension version to newer version in next release, which means will default with `I` 2.1, `A` 2.1, `F` 2.2 and `D` 2.2.
