[erlang-questions] Question about the VM

[Anthony Ramine]

Did you try targeting Core Erlang first? Which primitives do you want to access in BEAM?

There are 1024 X registers, and Y registers are used for locals in functions, to save them when calling other functions.

You can find such information by reading the source code or various talk slides made by the OTP team these last years, but I can't help you find the links right now.
