the base pointer (A5), and because we don't use the stack for

call arguments, only regs. If this CG behavior changes, this

code might break. In that case an asm-written StackSwap+call

wrapper code is the solution. (Basically the reimplementation

of AROS' NewStackSwap or MorphOS' NewPPCStackSwap.) (KB) }
