5.3 Error Handling in LR-Family Parsing
As in LL(1) parsing, the driver discovers that something is wrong when a token which cannot be used in a reduction is pushed onto the stack. Error repair consists of adding or deleting tokens to restore the parse to a state where parsing may continue. Since this may involve skipping input, skipping to the next "fiducial" symbol (symbols that begin or end a construct, such as begin, end, semicolon, etc.) is often done.
