; This tests correct handling of empty aggregate parameters and return values.
|
|
; An empty parameter passed by value does not consume a protocol register or
|
|
; a parameter save area doubleword. An empty parameter passed by reference
|
|
; is treated as any other pointer parameter. An empty aggregate return value
|
|
; is treated as any other aggregate return value, passed via address as a
|
|
; hidden parameter in GPR3. In this example, GPR3 contains the return value
|
|
; address, GPR4 contains the address of e2, and e1 and e3 are not passed or
|
|
; received.
