Upon closer look it looks like this piece could use some improvement
as well: while presence of "hvcl" indeed always implies full support
for LVZ instructions, "hvcl" however isn't used anywhere in the
series, so it's not trivially making sense. It may be better to test
for an instruction actually going to be used like "gcsrrd". What do
you think?
Thanks for your advice, and I think both "hvcl" and "gcsrrd"
instructions which are supported by binutils mean that the cpu support
LVZ extension, so I think they have the same meaning there.
Thanks
