<pre>A simple testcase like:
void __stdcall StdcallFunc() {};
void Test()
{
asm ("call _StdcallFunc@0\n");
}
Throws:
testcase.c:7:1: warning: control reaches end of non-void function
[-Wreturn-type]
}
^
testcase.c:6:10: error: invalid variant '0'
asm ("call _StdcallFunc@0\n");
^
<inline asm>:1:20: note: instantiated into assembly here
call _StdcallFunc@0
^
Another variant like:
void Test2()
{
asm ("call %P[Func]\n" : : [Func] "i" (StdcallFunc));
}
Throws:
testcase.c:12:10: error: invalid variant '0'
asm ("call %P[Func]\n" : : [Func] "i" (StdcallFunc));
^
<inline asm>:1:20: note: instantiated into assembly here
call _StdcallFunc@0
