Hi,
After last changes comparison table is (no -ko flags used):

So, we need to work on typed integer variable optimisation to be perfect :)
The -ko compiler switch will decrease the cost of 13 test above to 12
level. Why you didn't use it?
actually, the reason is very simple. I was too lazy to compile test
code, so, I've just run it using hbrun.exe. I was unable to add -ko
switch, but I believe I'll get the same 4.61 for test13.
I'm really under express of your job.
It was not so difficult, but more routine job. In a last few days/nights
I moved dbtopas.lt domain to new openSUSE11.1 server. It was much more
difficult. I still have some questions, but perhaps on private mail,
since it is out of topic.
1) non-terminal symbol should be lowercase
2) terminal symbol can not be character. All ',', '(', ')' should be
changed to some define, like C_COMMA, C_LBRACKET, C_RBRACKET, etc. And
complex code has to be fixed to return these constants.
...
7) Bison allows access symbols not from current rule. Actually ParamOne
could be reached by $-1 from "middle C code", but these hacky solutions are
not allowed in lemon.
I'll try to put my hands on this, but these days I have more ideas than
time to implement it.
Best regards,
Mindaugas
