I shall try to find the related assembly reference (although it is not
quite easy for me, and may be fail to get it), or get parisc related
members confirmation.

Hope I can get related proof (related documents, or related members

It is lack of hardware and related software. And I found it firstly by
gcc5 compiler warning, then read through the code (together with some
gdb members), found it should be an issue.
