>From "info gcc",
`fastcall'
On the Intel 386, the `fastcall' attribute causes the compiler to
pass the first argument (if of integral type) in the register ECX
^^^^^^^^^^^^^^^^^^^
and the second argument (if of integral type) in the register EDX.
^^^^^^^^^^^^^^^^^^^
Subsequent and other typed arguments are passed on the stack.
The called function will pop the arguments off the stack. If the
number of arguments is variable all arguments are pushed on the
stack.
It looks like gcc document follows MS compiler and we didn't implement
it correctly.
