           Summary: abi spec is unclear on parameter passing

        OS/Version: All

the spec says the last parameter is passed in EAX, from just reading the spec it's unclear (to me) what counts as the last parameter.

for example, the 'this' pointer is not passed in EAX even though it's the last thing passed and does fit in EAX

'this' is passed last, and in the EAX register. For example,

class A
{
    int x;
    void foo() { x = 3; }
}

results in:

_D5test51A3fooMFZv      comdat
        assume  CS:_D5test51A3fooMFZv
                mov     dword ptr 8[EAX],3
                ret
_D5test51A3fooMFZv      ends
