Pauli Oikkonen 686fb2c957 Unroll arbitrary-width SSE4.1 hor_sad by 4 2019-02-04 20:41:40 +02:00
Pauli Oikkonen 768203a2de First version of arbitrary-width SSE4.1 hor_sad 2019-02-04 20:41:40 +02:00
Pauli Oikkonen ccf683b9b6 Start work on left and right border aware hor_sad 
Comes with 4, 8, 16 and 32 pixel wide implementations now, at some point
investigate if this can start to thrash icache
