This patch extends the specs for the following built-in functions:
* process_flag/2,3
* system_flag/2
* system_info/1
* spawn_opt/2,3,4
The main intention for this patch was to make dialyzer recognize the process_flag option 'sensitive'. When fixing this issue I noticed some more missing specs and added what I could find in the latest documentation.
Regards
Tobias
