* x86: Move XOP emulation to x86utilJames Almer2014-02-242-19/+19
| | | | | | | | | | | 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 <[email protected]> Signed-off-by: Michael Niedermayer <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | Prevents a crash if the misaligned exception mask bit is cleared for some reason. Misaligned SSE functions are only used on AMD Phenom CPUs and the benefit is miniscule. They also require modifying the MXCSR control register and by removing those functions we can get rid of that complexity altogether. Signed-off-by: Derek Buitenhuis <[email protected]>
