== Justification ==
The copy_unaligned / paste_unaligned / paste_last_unaligned test in powerpc/alignment will fail on a Power9 node as which implements ISA 3.0B, but the test was designed base on ISA 3.0.
From commit message:
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.
== Fix ==
* 83039f22 (selftests/powerpc: Remove Power9 copy_unaligned test)
Patch can be cherry-picked into C, for Bionic it needs patches for bug 1828935 to land first to make it a clean cherry-pick.
It's already landed in D and onward.
== Test ==
Tested on a Power9 server with Cosmic, the broken tests will be removed correctly.
== Regression Potential ==
Low.
Code change limited to testing tools and just removing broken tests. We still have copy_first_unaligned to test the "copy first" behaviour.

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.
== Fix ==
* 83039f22 (selftests/powerpc: Remove Power9 copy_unaligned test)
Patch can be cherry-picked into C, for Bionic it needs patches for bug 1828935 to land first to make it a clean cherry-pick.
It's already landed in D and onward.
== Test ==
Tested on a Power9 server with Cosmic, the broken tests will be removed correctly.
== Regression Potential ==
Low.
Code change limited to testing tools and just removing broken tests. We still have copy_first_unaligned to test the "copy first" behaviour.
== Original Bug Report ==
This issue was only spotted on Power9 system "balter", for Power8 system, it has passed (skipped, and marked as passed) with this test:

== Justification ==
The copy_unaligned / paste_unaligned / paste_last_unaligned test in powerpc/alignment will fail on a Power9 node as which implements ISA 3.0B, but the test was designed base on ISA 3.0.
From the commit message:
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.
