| # The powerpc backend doesn't support the quadword load/store instructions yet. |
| # So they are tested by linking against an object file assembled with |
| # `as -mpower9 -o ppc64le-quadword-ldst.o in.s` and checking the encoding of |
| # the unknown instructions in the dissasembly. Source used as input: |
