Re: [PHP-DEV] GOTO operator

[Alan Knowles]

if you look at the bison/flex, they both use switch/case - the parsers I 
use,  both generate code like this, however they ended up using variable 
functions, as even the overhead of the function calls is faster than the 
large switch/case called repeatidly.. (this is ideally what dynamic 
goto's could replace)

re2c uses goto's with static addresses. - I doubt though it would be 
easy to modify the parser generators I have to do this..

No idea how lemon works?..
The other alternative would be to do some apc optimization on 
switch/case with integers...

That kind of makes them useless for writing parsers, which was one of 
the justifications of them.

How that? C doesn't have dynamic goto targets either
but still its used for parsing lot ...
