Hi, I am using ANTLRWorks 1.2.2 with ANTLR 3.1.1 in my previous work. My target language is C. It works well, but the performance is awkful. Moreover, the time consumption looks non-linear, although there is (almost) no backtrack in my grammer file. It costs about 3 seconds for parsing 30k lines of script file, and 12 seconds for 60k lines.
Today I upgrade it to ANTLRWorks 1.4/ANTLR 3.2, and the performance is improved dramatically. It cost less than 1 second for 60k lines. More than 10X of speed ! I am glad for such a result, but it also takes a little worry to me. How do you(Jim Idle or others) improve that between ANTLR 3.1.1 and ANTLR 3.2? Does it reliable? Or is there any side-effect with that? Anyway, thank you for your excellent work!
