C code :
DECLARE_ALIGNED(16, const int8_t, ff_hevc_epel_filters[7][16]) = {things}

"my" is an argument which takes a value between:
void ff_hevc_put_hevc_epel_v_8_sse(things,  int my, things)
    const int8_t *filter = ff_hevc_epel_filters[my - 1];
    int8_t filter_0 = filter[0];
	things...

	sub    r6,1
	shl    r6,4
