x86: move XOP emulation code back to x86inc
Only two functions that use xop multiply-accumulate instructions where the first operand is the same as the fourth actually took advantage of the macros. This further reduces differences with x264's x86inc. Reviewed-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: James Almer <jamrial@gmail.com> |

x86: Move XOP emulation to x86util
We need the emulation to support the cases where the first argument is the same as the fourth. To achieve this a fifth argument working as a temporary may be needed. Emulation that doesn't obey the original instruction semantics can't be in x86inc. Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at> |
