[PATCH] D112408: [RISCV] Add the zve extension according to the v1.0 spec

[Yueh-Ting Chen via Phabricator via llvm-commits]

eopXD updated this revision to Diff 384972.
eopXD added a comment.

Change:
After adding extension `zve`, the minimum requirement of vector instructions isn't `v`.
Let `__riscv_vector` be indicator if any vector extension is available.

Sent a proposal to the riscv-c-api-doc: https://github.com/riscv-non-isa/riscv-c-api-doc/pull/22
