It is exactly like %pure-parser. It does not select a different
skeleton. In fact, %pure-parser uses the yacc.c skeleton.

Oh, great!  I wasn't sure you managed to implement the push parser in
yacc.c itself.  Did you try to bench your yacc.c in pull mode vs. the

No, I didn't really understand how to do that thoroughly. Do you have any

Yes, there are a couple of large grammars in the testsuite. I'll toy with you yacc.c do bench it.
