What is the process so that information regarding PPC64 libmvec is added to
https://sourceware.org/glibc/wiki/libmvec?
I think it would be enough if in the introduction, a note is made that a PPC64 implementation
exists and provide a link to the Power Vector Function ABI document. This should mean the
latest version of the ABI document be uploaded to sourceware.org/glibc as was done for
x86_64 Vector ABI at URL:
https://sourceware.org/glibc/wiki/libmvecaction=AttachFile&do=view&target=VectorABI.txt
Thanks.
Bert.
