RETAIN_UNNORMALIZED_C_AST 設定を追加してください。
RETAIN_UNNORMALIZED_C_AST = Yes WARNING_FILTER += allow class="Too Many Side Effects in Function Call" |
extern int x, y; extern int f(int); /* Functions are assumed to have side effects unless * SIDE_EFFECT_FREE_FUNCTIONS specifies otherwise */ extern int g(int, int); void too_many_side_effects_call(void){ f(x*=2); /* only one side effect */ g(f(y), x); /* only one side effect */ g(x+=2, y+=4); /* 'Too Many Side Effects in Function Call' warning issued here * - 2 side effects */ g(x, y=(x+=5)); /* 'Too Many Side Effects in Function Call' warning issued here * - 2 side effects */ }
設定ファイルの以下のパラメータがこのワーニングクラスのチェックに影響します。
