Subject: Re: [PATCH 2/2] riscv: Add vector ISA support

Let's talk about libc abi for sigcontext and our cpu has the vector
features, so we need start the work to support stress-test.

I think it's the same to andes, because andes also announced the
vector processor. The linux and libc are only small part of vector
ISA, let's work together :)
