Line 46:
A function's "return value" is nothing more than the register state upon exit. However, to ensure compatibility between software, there are general calling conventions that compiler-written code will follow that standardizes which registers are used to return values from a function.
This code returns the sum and difference of two integers, which will be passed in via registers D2 and D3.
<lang 68000devpac>sum:▼
D2+D3 is returned in D0, D2-D3 is returned in D1.
MOVE.L D2,D0
MOVE.L D3,D1
ADD.L D1,D0
SUB.L D2,D3
MOVE.L D3,D1
