Hi all,
There's an unexpected behavior I can't understand when I compile some
Ada code with Asm() directive. In the following example, code compile
with no problem :
...
procedure Main is
Foo : Integer;
begin
Foo := 1; -- Foo is initialized here !
System.Machine_Code.Asm(
"movl %0, %%eax",
Inputs => Integer'Asm_Input("m", Foo),
Volatile => True
);
...
Why no trying to initialize `Foo' variale during its declaration ? The
code is exactly the same except for `Foo' :
procedure Main is
Foo : Integer := 1; -- Foo is initialized here !
begin
But then, compilation fails with that message : "error: memory input 0
is not directly addressable"
Someone have an explanation ?
