Abstract syntactic tree treatment manner, computer reading possible record media, record the abstract syntactic tree data computer reading possible record media, and the abstract syntactic tree central processing unit which record the abstraction syntactic tree treatment program

摘要

Abstract Topic It inputs in specification of programming language which alterationBeing, be able to utilize the source code of the treatment that wayIt makes the ru way. Solutions The tag of the abstract syntactic tree which becomes the target of treatment pitchDue to be ru thing, it decides whether the node literal or syntaxru (step S01). In case of literal, literal tagYou inspect, the treatment which is individually necessary (step S 21, S 22..) It does. However, in the literal individual treatment there is no necessity oppositeGeneral for other literal treating (sutetsupu S02j) it does. In case of syntax, tag therefore branchingIt is individually necessary in every type of syntax, it treats (step S03₁, S 32.) it does. However, individual treatment there is no necessityVis-a-vis syntax, the general treatment for other syntax (sutetsupu S03k) it does. In case of syntax, the abstract structure which is in the midst of treatingThe sub tree which the statement tree has vis-a-vis entirely, recursively suteIt treats from tsupu S01 (step S04). Tree structureWhen the node is literal, judge the terminal,Is possible.
