[llvm-dev] Malloc null checks, why sometimes are moved and sometimes not?

[Dávid Bolvanský via llvm-dev]

Hello,


Here is simple test code:
https://godbolt.org/g/mjAUpu

LLVM generally assumes that malloc never fails.

But I dont understand difference between these two example functions - and
why null check was not removed in f1, since in f2 it was removed.

Thanks
