Advanced Error Recovery during Top-Down Parsing
 Obluková, Alena ; Kolář, Dušan (referee) ; Meduna, Alexandr (advisor)
Parser is one of the most important parts in compiler since Syntax-Directed Translation is often used. This approach means that parser controls semantic actions and generation of syntax tree. When the input contains an error, parser cannot continue and the whole compiler has to stop. Therefore, it is important to have parser with error recovery, so when error occurs parser is able to continue. There are several error-recovery strategies and methods. In this paper is described Acceptable-sets derived from continuations specifically continuation in LL parsers. However it is not so well known method it is easy to explain and to implement. It can be used in the lesson to demonstrate error recovery in top-down parser.
