[erlang-questions] NIF + HiPE - can it works together?

[Sverker Eriksson]

I don't know if it has been stated, but HiPE and NIFs do not play nice 
together *within the same module*.
Using HiPE and NIFs on different modules within the same VM will 
hopefully work fine.


There seem to be a number of problems here.

1. erlang:load_nif fails as reported by Radosław Bułat. This seems to be 
a "simple" bug that can be fixed, but even if so...

2. The NIF overriding mechanism is not implemented for hipe and would 
probably yield unpredictable results.

3. Hipe compiler fails on on_load as reported.

I will look into the first two.  Not sure if #3 was expected not to 
work? (Mikael? Kostis?)
