[libav-devel] [PATCH 1/6] arm/aarch64: vp9lpf: Calculate !hev directly

2017-01-15 Thread Martin Storsjö
Previously we first calculated hev, and then negated it. Since we were able to schedule the negation in the middle of another calculation, we don't see any gain in all cases. Before: Cortex A7 A8 A9 A53 A53/AArch64 vp9_loop_filter_v_4_8_neon: 147.0 129.0
