# Basic info This is a subtask of #1009 - it splits off the complexity optimization of the function L_norm_arr(). This optimization is BE. # Bug description Avoid `IF()`-operator in the `FOR`-loop; the `IF()` operator has a complexity count of 3; instead, `if()` can be used if it conditions only one basic operator (control operators excluded). ``` Word16 L_norm_arr( Word32 *arr, Word16 size ) { Word16 q = 31; move16(); FOR( Word16 i = 0; i < size; i++ ) #ifndef PATCH IF( arr[i] != 0 ) { q = s_min( q, norm_l( arr[i] ) ); } #else { Word16 q_tst; q_tst = norm_l( arr[i] ); if ( arr[i] != 0 ) { q = s_min( q, q_tst ); } } #endif return q; } ``` This saves 2-3 cycles per iteration at minimum cost (one additional 16 bit word on stack). # Ways to reproduce See #1009 for commandline.
