This is not what I understood, there is some kind of flags required for pointers or something, which requires a data section for basic primitive types.
I'm afraid I'm not sure what you're referring to. For instance, I can build a simple Hello World in Zig using `zig build-exe`, and get a static executable, on which I can use `nm` to confirm that there aren't symbols from any kind of runtime. I can even trivially build the actual Zig compiler to a static binary.
(For context, by the way, I'm on the Zig "core team"; I'm a notable contributor to the project.)
mmmmh... basically, generates machine code which only requires a stack (which could be used by code paths not written in zig), contained in memory pages with execute and read permission only. Ofc this machine code would interact with the other machine code (written in other languages) via the architecture calling convention (the ABI/C one).
