Re: Why does the RTS run GC right before shutting down?

We already run all finalizers after exitScheduler: https://github.com/ghc/ghc/blob/master/rts/RtsStartup.c#L382-L388 so no need to run GC for that. Ömer 2018-04-06 17:06 GMT+03:00 Edward Z. Yang :

I believe it's so that we can run finalizers before shutdown.

Hi,

I'm wondering why we run GC in this line:

https://github.com/ghc/ghc/blob/master/rts/Schedule.c#L2670

I went back in commit history using git blame and found the commit that introduced that line (5638488ba28), but it didn't help. Does anyone know why we need that line?

Thanks,

Ömer
