The code for a ROM call is exactly the same as the code for a procedure call
to a prodecure of an other module. The placing of parameters into registers
doesn't make a big difference. With other compilers you have an external call
to the assembler stub popping parameters into registers and eventually pushing
results back on the stack again and the basic ROM call.

Simplified: The time others arrive in their stubs we arrive at the function in
ROM. 

A German jounalist doing some reseach on this came up with following figures.
machine cycles for a Library Call.
TDI ~250, Manx ~140, M2Amiga 94, he complained because the optimal Assembler
call only uses 74 cycles. This still leaves some space for improvement :-)

You won't be disappointed, I hope.
M2Amiga is in stock, should I reserve a copy for you :-)
