This is a test of the ISA 3.0 "copy" instruction. That instruction has an L field, which if set to 1 specifies that "the instruction identifies the beginning of a move group" (pp 858). That's also referred to as "copy first" vs "copy". In ISA 3.0B the copy instruction does not have an L field, and the corresponding bit in the instruction must be set to 1. This test is generating a "copy" instruction, not a "copy first", and so on Power9 (which implements 3.0B), this results in an illegal instruction. So just drop the test entirely. We still have copy_first_unaligned to test the "copy first" behaviour.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
