[x265] [PATCH 0/6] AArch64: Add more optimisations to interp functions

[chen]

Hi Gerda,




Thanks for the patches, most looks good to me, just a little comment,

+void inline filter8_s16x4(const int16x4_t *s, const int16x8_t filter,
+    else if (coeffIdx == 2)
+    {
+        int16x4_t sum07 = vadd_s16(s[0], s[7]);
Is this risk for overflow?




Regards, Chen
