Well, not really. The compiler just places them in the .bss area.  It
is barebox, it is run-time initialization, that zeroes bss.

So it is barebox, not the compiler.

Uwe, I know you know this, but I'd better make it clear for
everybody. I've already seen a "specialist" writing an IPL where he
explicitly sets static variables to 0 one by one in different places
because he didn't clear bss in his assembly.
