Re: [SharpOS Developers] short wiki guide on writing tests for the AOT

Hi

The HowTo is really great and I am glad we have it finally. :D

There is only one thing that should be changed and that is the Test Case 
Example.
The AOT already does some basic constant folding that means that when it 
finds something like 1+2
then it computes that so the if statement becomes if (3 == 3). Other 
optimizations will come later
and the whole code can be reduced to "return 1;".

So it would be great if the CMP method calls another one that does the 
test and CMP only compares the result and returns 1 or 0.
Something like this:

        public unsafe static uint Misc2 (uint granularity)
        {
            switch (granularity) {
                case 0:
                    return 4096;
                case 1:
                    return 131072;
                default:
                    return 0xFFFFFFFF;
            }
        }

        public unsafe static uint CMPMisc2a ()
        {
            if (Misc2 (0) == 4096)
                return 1;
               
            return 0;
        }

That way there will be no such optimizations and the test will be more 
reliable.
