profiling in prolog

[Tiago Bordoni]

Hi.

I´m working in a project for my graduation that a have to do some profiling in prolog code and write this data in a new .pl archieve.
My problem is that a don´t know which place and struct that has the prolog code that is read from the archive in the moment that i load it.
The profiling information is in a new struct that i created in pred_entry struct.
Which struct or global variable that have then start list of pred_entry vars?
Wich struct or variable have the .pl source read in the load?

thanks for all.

Hi Tiago

Sorry for the delay. I couldn't understand your question very well :(

YAP has this hook ap_inform_profiler_of_clause and
ap_inform_of_removal that are called whenever you add or remove code.
They are implemented in gprof.c and you should look at them first, I
think.

YAP does not keep the source of facts. Instead, it uses unification to
recover the fact. Sources for rules are kept in a ClSource field of
each clause structure. The code for clause in cdmgr.c is a bit
complex, but that's how YAP recovers source.

Sorry again for the delay :(
