#define CHECK (   j)
Value:
{ int score = FFABS(cur[mrefs - 1 + (j)] - cur[prefs - 1 - (j)])\
+ FFABS(cur[mrefs +(j)] - cur[prefs -(j)])\
+ FFABS(cur[mrefs + 1 + (j)] - cur[prefs + 1 - (j)]);\
if (score < spatial_score) {\
spatial_score= score;\
spatial_pred= (cur[mrefs +(j)] + cur[prefs -(j)])>>1;\
#define FFABS(a)
Absolute value, Note, INT_MIN / INT64_MIN result in undefined behavior as they are not representable ...
