[antlr-interest] synpred/DFA error

[Ilia Kantor]

Hello,


There is a rule in my grammar:
rule_long_def_part:
	  MINUS GT WORD ((get_property_arguments)=> get_property_arguments)* |
	  DOT WORD 
	;

If backtracking = true
	ANTLR generates synpred for
	( ( get_property_arguments )=> get_property_arguments )*

!!	That works correctly.

If backtracking is off, 
	ANTLR generates DFA and calls predict() method.

?? 	That gives wrong alt.


I'm not sure where to dig, is the overall behavior sane ?

No errors/warnings in both cases, Java files are essentially same excepts DFA/synpred difference.
