語法樹 的英文怎麼說
中文拼音 [yǔfǎshù]
語法樹
英文
syntactic [syntax] tree-
A sentence of a grammar is ambiguous if there exists two syntax trees for it.
如果一文法的句子存在兩個語法樹，那麼該句子是二義性的。A parse of a sentential form is the construction of a derivation and possibly a syntax tree for it.
句型的分析是某個推導（或許是其語法樹）的構造過程。The gcc compiler scales very well - from simple batch utility programs to multimillion - line systems. it is the clear syntax tree front end, the highly recapitulative intermediate language and the concise machine description back end that help gcc port to kinds of platforms
其清晰的前端語法樹結構、高度概括的抽象機中間語言、簡潔有力的後端機器描述等三部分為快速實現多語種開發、多平臺移植提供了有力的支持。If a sentential form is ambiguous, then it has more than one syntax tree and therefore, in general, more than one handle.
如果句型是二義性的，那末，它不只有一棵語法樹，因此，一般地說，也不只有一個句柄。A parse of a sentential form is the construction of a derivation and possibly a syntax tree for it
句型的分析是某個推導（或許是其語法樹）的構造過程。According to the program structure of ansi c, some syntax - tree - nodes are designed in front - end, including function, block, data structure, type, expression, identifier and so on. syntax tree is divided into three levels, namely program level, function level and block level, which are useful for analysis of syntax and semantic in compiler as well as transferring syntax tree into rtl. retargetable compiler mainly includes intermediate representation, machine description and interface technique between compiler and machine description
編譯前端的實現技術包括詞法分析、語法語義分析和中間代碼生成技術等，針對ansic的程序結構，分別設計了函數、塊、數據結構、類型、表達式、標識符等語法樹結點，並將語法樹分成編譯層次、函數聲明和塊三個不同層次，使語法樹具有清晰的層次結構，有利於編譯程序的語法和語義分析，以及從語法樹到rtl中間表示的轉換。An integrated ufo _ syntax _ tree is built
建立一顆完整的ufo語法樹。C c abstract syntax in software instant test
抽象語法樹的生成Generating abstract syntax trees
生成抽象語法樹Traverses the abstract syntax tree one or more times, collecting information and checking that the input program

摘要提出了一種基於分層思想的，並且無需構造具體語法樹的變量類型提取方法。An abstract syntax tree is built after syntax analysis and traversed three times to do semantic analysis to generate the intermediate code
在語法分析、語義分析及中間代碼生成方面，先經過語法分析建立抽象語法樹，然後對抽象語法樹進行三次遍歷完成語義分析並生成中間代碼。It takes a plain javacc grammar file as input and automatically generates the following : a set of syntax tree classes based on the productions in the grammar using the visitor design pattern ; two interfaces visitor and objectvisitor ; two depth - first visitors depthfirstvisitor and objectdepthfirst ; and a javacc grammar with the proper annotations to build the syntax tree during parsing
它把普通的javacc語法文件作為輸入並自動生成下列各項：基於語法中的生成的一組語法樹類（使用visitor設計模式） ；兩個介面（ visitor和objectvisitor ） ；兩個深度優先訪問器（ depthfirstvisitor和objectdepthfirst ） ；和一個帶正確注釋的javacc語法（用於在解析期間構建語法樹） 。You can add new rules, either by writing java code and recompiling pmd or, a little more simply, by writing xpath expressions that are resolved against each java class s abstract syntax tree
您可以添加新規則：可以通過編寫java代碼並重新編譯pdm ，或者更簡單些，編寫xpath表達式，它會針對每個java類的抽象語法樹進行處理。You would never use a scanner to analyze an entire java source ; for that you would turn to something quite familiar to compiler aficionados : the jdt s abstract syntax tree framework
您決不會使用掃描程序分析整個java源代碼；因為您會轉而使用一些對編譯器迷而言十分熟悉的工具： jdt的抽象語法樹（ abstract syntax tree ， ast ）框架。Existent automatic grading model of programs can not deal with the programs with structural body. in this paper, we study the syntax and concept of structural body based on an existed model, and improve the original model in the following aspects : increasing the middle representation form of structural body in analysis of morphology and syntax and system dependence graph and abstract syntax tree, adding standardization rules, mainly including type definition, nesting structure, initialization, function invocation, renaming and sequence of program sentence, besides standardization rules of bit operation and program with enumeration, enhancing the function of inspecting syntax error and improving matching strategies
