<h3>

|
Next Release + 1</h3>
|
|
<ul>
|
|
<li>Throw exception on null ref...</li>
|
|
<li>Plugs - warn if plugging something that doesnt exists... caused the x08 bug?</li>
|
|
</ul>
|
|
<ul>
|
|
<li>(joint with Kudzu) - Move all critical plugs out of old asms and remove building
|
|
of old asms.<ul>
|
|
<li>And the plugs also from CustomImplementations in IL2CPU?</li>
|
|
</ul>
|
|
</li>
|
|
<li>Exceptions dont work. Try int.parse("asdf"). It runs but when the exception is
|
|
hit we get garbage back instead. (ie exceptions through plug proxy dont work)</li>
|
|
</ul>
|
|
<ul>
|
|
<li>IL2CPU.AlwaysCompile attribute and get rid of IDT.Dummy</li>
|
|
<li>int j = Array.IndexOf(Digits, s[i]);<ul>
|
|
<li>When Digits is a char array, we get a plug needed error.</li>
|
|
</ul>
|
|
</li>
|
|
<li>cxdb contains full asm path and filenames over and over... cant we write them
|
|
out once and use a byte/word index to identify them? This will make it smaller
|
|
and make reading faster.</li>
|
|
<li>Plugs
|
|
<ul>
|
|
<li>Source Plugs - Leave as they are</li>
|
|
<li>Assembly Plugs - Change to have attribute on the TARGET instead of the
|
|
implementation and only allow assembly.. this cuts out the "proxy" class and
|
|
makes it easier to find plug impls. See Rings.html for more info. The assembly
|
|
level plugs can even go in the same assembly, source file and if we can the same
|
|
class? That is currently these assembly plugs require 3 classes to implement.
|
|
its ugly and messy... we can get it down to 2 - 1 + assembly (X# only!). Current
|
|
way is such a mess we even comment them as plugged, but then have to go guessing
|
|
where the impl is... See example down below....</li>
|
|
<li>Convert all source plugs and disable old attributes...so for new ones use new
|
|
names</li>
|
|
</ul>
|
|
</li>
|
|
<li>We need to dynamically
|
|
load the plugs etc so we can just rebuild and run and even trace them without
|
|
rerunnig the bat for each change</li>
|
|
</li>
|
|
</ul>
|
|
<ul>
|
|
<li>Ring attributes and enforcement<ul>
|
|
<li>Also allow restriction of assembly references</li>
|
|
<li>Only allow core to be /unsafe, no others</li>
|
|
</ul>
|
|
</li>
|
|

Assembly Plug Example</h3>

<h4>

Old way</h4>

|

(3 classes, often 3 source files as well)</p>
|
|

|
|
public override void AssembleNew(Cosmos.Assembler.Assembler aAssembler, object aMethodInfo) {
|
|
//TODO: This is a lot of work to write to a single port. We need to have some kind of inline ASM option that can emit a single out instruction
|
|
new CPUx86.Move { DestinationReg = CPUx86.Registers.EDX, SourceReg = CPUx86.Registers.EBP, SourceDisplacement = 0xC, SourceIsIndirect = true };

See how much neater and self contained this is? :)</p>
