    selftests/powerpc: Remove Power9 copy_unaligned test · 83039f22
    Michael Ellerman authored
    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.
