From 83039f22ba2f6aff935a2acbb6bf671374e8317d Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Wed, 11 Jul 2018 17:10:15 +1000 Subject: selftests/powerpc: Remove Power9 copy_unaligned test 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.
