Re: Heap allocation in the RTS

allocateMightFail does the heap check for you and returns NULL. For the current capability you can use MyCapability() in Cmm and pass the value to the RTS function you're implementing. Ömer David Feuer , 20 Eyl 2018 Per, 12:26 tarihinde şunu yazdı:

Aha! Okay. How do I get the current capability to pass to that? I guess I should probably perform a heap check before calling lookupSta bleName for simplicity, at least to start.

Have you seen Storage.c:allocateMightFail ?

I'm working on re-implementing the stable name system. For the new design, it seems much cleaner to allocate stable names in lookupStableName (in rts/StableName.c) rather than in the C-- code that calls it. But I haven't seen RTS code that does heap allocation. Is it possible? If so, how do I do it? _______________________________________________ ghc-devs mailing list ghc-devs@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/ghc-devs
