I prefer not to bet at all. ;)
Let's make this:
asm ("");
(asms without input and output operands are volatile, and we're
also leaving the text empty) in the called function the
promised, documented way to stop interfunction analysis (like
currently const/pure) making calls "as it used to be". Not all
targets support "weak", and overloading a standard qualifier
like "volatile" or "extern" seems on second thought too brittle.
