Implementation of my own BIF function

[Sergey Loguntsov]

Hi, everybody.

I tried to implement my own BIF-function which is implemented inside Erlang
sources.

So i made sources of this function in erts/emulator/beam/bif.c and i have
changed erts/emulator/beam/bif.tab
(
https://github.com/loguntsov/otp/commit/7a28a3d99b0c7795d956caec5e4e397183dd1ea9
)
i found also i must change erts_internal.erl module in /erts/preloaded/src
folder.
So i made it:
https://github.com/loguntsov/otp/commit/84c4bfb8c372ade9d92c4a20515f91fe33062b1d

My problem is .. there are prebuilded files based on erts/preloaded/ebin
and actually they are not updating every time what i'm building Erlang.
They are committed as part of sources (seems this is big crutch).
So my question is what is right way to update preloaded modules (beam
files) ?
May be there is another way to have BIF function outside from Erlang
sources ? and building them together ?

Regards.
