[PATCH] D85069: [RISCV] add the MC layer support of riscv vector Zvamo extension

[Hsiangkai Wang via Phabricator via llvm-commits]

HsiangKai added a comment.

I confused the relationship of sub-extensions before. Sorry for that.
There are some discussions[0] about the relationship between vector sub-extensions. It seems that


V-extension implies Zvamo + Zvlsseg

Zvqmac, Zvamo and Zvlsseg are stand alone sub extensions. That is, Zvamo does not imply V extension.

Zvqmac has no implied extensions.
Zvamo implies A-extension.
Zvlsseg has no implied extensions.

Do you agree with that?
