C语法归约之表达式(3)
1、概要
前三篇博文(0,1,2)主要讨论是声明和定义的相关语法归约。从这篇文字开始,将开始进行有效的计算,涉及表达式和语句。
首先,表达式和语句这两个概念是不同的,表达式是没有分号(;)的,而表达式+;构成语句。但这不是语句的全部,语句还可以是跳转,迭代,标签语句等等(见图片C语句文法图)!打个比喻来说吧——就是蛋和鸡的关系!当然不是那个悖论,而是表达式是蛋,孵化是分号,鸡是语句。蛋孵化成鸡。鸡肚子里可以有蛋!嘎嘎!二者区别必须明白。不能混为一谈!
在C语言中,如果单纯就表达式计算而言,表达式就是一个人,而分号;好似一张毕业证,有它你就是正规的劳动人员,哪怕你什么都不干什么都不会(比如单个分号;)而没它,你就是没户口的黑孩,不能参与计算劳动,编译器抱怨的不得了,就是不让你上岗运行!
其次,说到表达式,运算符的优先级问题就不得不提一提了。C中的优先级是由表达式文法决定的!当初学C的时候都是死记硬背的,那时候觉得这个优先级是C它爹里奇严格要求,每次运算的时候都要检测后面的优先级,看它是不是比当前运算符优先级高。而且一直觉得编译器也是这样做的。而事实上不是,广义上讲是严格要求,因为它已经写入了文法,归约顺序是固定的,就像法律条文一样,是严格约束的;但是从狭义上而论。这个优先级是很自然的事情,不需要摇头晃脑的背,也不用比较优先级高低来实现,而是语法归约过程很自然的东西。一级一级的归约,一级一级的蹦哒,到了哪个阶段,那个阶段归约,优先级自然就隐含在里面了!它们的归约顺序决定了它们优先级!
通过表达式对归约过程的理解,把它画成一个顺时钟的表圈更直观!如上图所示!(图片较大,另存为下载可正常查阅)
在中心处写了一段:运算符的结合只能从高到低而不能逆向进行(归约箭头方向决定了),较低运算符优先结合的方法是使用()在零点方向。()是相当复位运算符,使得较低运算符能够回到最高优先级处改变运算符结合顺序!这样较低运算符能够先运算之后再和较高运算符结合;注意归约过程不会跳跃!(下文示例可以得知这一点)即向‘上游’运算符结合,必须顺时钟走一圈,并且使用了(),否则达到零点前expression处就归约停止!
举个简单例子帮助理解这一段话:a+1<<8和a+(1<<8)
a+1<<8归约过程 a是id->primary-expr->postfix-expr->unary-expr->cast-expr->mul-expre->additive-expr(暂停) + 1是constant->primary-expr->postfix-expr->unary-expr->cast-expr->mul-expr(暂停) 然后additive-expr+mul-expr->additive-expr->shift-expr << 8是constant->primary-expr->postfix-expr->unary-expr->cast-expr->mul-expr->additive-expre(暂停) shift-expr<<additive-expr->shift-expr->relational-expr->equality-expr->...->expr(暂停) a+(1<<8)归约过程 a是id->primary-expr->postfix-expr->unary-expr->cast-expr->mul-expr->additive-expr(暂停)+(1是constant->primary-expr->postfix-expr->unary-expr->cast-expr->mul-expr->additive-expr->shift-expr(暂停)<<8是constant->primary-expr->postfix-expr->unary-expr->cast-expr->mul-expr->additive-expr(暂停)shift-expr<<additive-expr->shift-expr->relational-expr->equality-expr->...->expr(暂停))(expr)->primary-expr->postfix-expr->unary-expr->cast-expr->mul-expradditive-expr+mul-expr->additive-expr->shift-expr->...->expr
注意区分它们的不同!或许你会问如何知道到什么时候需要暂停,什么时候继续归约?答案就在非终结符的follow基上!什么是follow集以及first基,请参与《编译原理》第4章语法分析部分!这里就不重述了!
在这里你只需要知道:当下一个运算符是当前非终结符要归约到的非终结符的follow基时,则继续归约,否则暂停。比如上面这个例子1的归约shift-expression的follow基包含<<,那么additive-expression就需要归约到shift-expression,再往下,relational-expression的follow基不包含<<,所以shift-expression就到此暂停,不能再归约下去!而等待其他部分(<< 和additive-expression)到来,再一起归约!
如果上文看不懂,不要紧,在下面的示例中会给出很多组合范例,可以多看几个就理解了,当然你要结合C99文法或者上图来理解!
最后,为了更好描述原理,这里要相对前面的声明定义而言做些调整!单个示例进行提示!表达式示例分两大类,基本常用和高级复合!在此文将给出基本常用表达式归约。下一篇给出复合表达式归约。
输出依旧老风格,整个归约栈,其实是一颗树,只不过是栈的形式描述的。每次归约都是从孩子到父亲的建树过程,因为这是LR(1),自底向上!(LL正好相反,自顶向下)整个归约纳入一个函数当中,每次栈的输出开头“declaration-specifiers declarator { block-item-list“它属于函数归约的部分,压在栈中而已,可以忽略不看,重点在表达式的归约上!另外,表达式之间过度部分如下,也可以忽略不看!
declaration-specifiers declarator { expression-statement declaration-specifiers declarator { statement declaration-specifiers declarator { block-item declaration-specifiers declarator { block-item-list
