Out parameter was not generated properly #8

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
To reproduce the bug:

        public static void GenFoo(AssemblyGen tg)
        {
            TypeGen g = tg.Public.Class("OutParameterBug.Foo");
            {
                CodeGen cg = g.Public.Method(typeof(void),
"OutParamMethod").Out.Parameter(typeof(long), "l");
                {
                    cg.Assign(cg.Arg("l"), 0);
                }
            }
        }

Expected:
    .method public hidebysig instance void OutParamMethod([out] int64& l)
cil managed

But actual generated IL code that is missing [out]:
    .method public hidebysig instance void OutParamMethod(int64& l) cil managed
    {
        .maxstack 2
        L_0000: ldarg.1 
        L_0001: ldc.i4.0 
        L_0002: conv.i8 
        L_0003: stind.i8 
        L_0004: ret 
    }

I believe this is mostly a cosmetic issue and shouldn't affect the runnability 
of the 
code in any way, since ref and out parameters are the same beast internally, 
and only 
have different compile-time semantics.

What if you care to write the dynamic module to an dll file?

Well, it'll probably force you to initialize the holders for out parameters 
before calling the method, and write ref 
instead of out ;) Anyway, it's trivial enough to be fixed in 0.2, which I hope 
will be sometime during holidays.
