Re: [cdt-dev] Codan performance

[maximed@xxxxxxxxxxxxxxxxxxx]

Hi.
Got a solution here. I don't have performance problems, but my problem  
is near yours: the more errors there are, the less it is usefull.
Our ideas here:
     1/ Insert a #pragma in the file for each checker you don't want to use
     2/ Put the same type of information in comments.
I know, the problem is that it changes the code (which is no loger  
valid in my case).

So:
     3/ Define a XML which specifies, for each file you don't want to  
use all checkers on, which checker you wanna disable. Then, when  
launching checker, insert a XML files reader that computes all you need.

I'm interrested in your needs and remarks, tell me if it sounds a good  
idea for you.
