The virtual argument pointer is pointing to the bottom of the argument
transfer area, which is located immediately below the virtual frame

(for the no arguments case) or large enough to hold all argument registers.

+ gcc uses a variable sized argument transfer area. As it has
to stay compatible with the native debugging tools it has to use the same
virtual argument pointer and adjust the argument offsets accordingly.
