I'm looking into it. I've created another small patch, which seems to almost work, except for a problem with the register allocation, which I can't fix right now.
The line foreach (INode node in _devices), where _devices is a
InternalSystem.Collections.Generic.List<INode> doesn't pass the AOT. With
this patch it does pass, but fails later on in the register allocation in
register.Version = ++this.method.RegisterVersions [this.stack.Count];
In SharpOS.AOT.IR.Block::SetRegister.
The method compiled is:
public INode Lookup(string name)
{
foreach (DeviceNode device in _devices)
{
if (device.Name == name)
{
return device;
}
}
return null;
}
Where _devices is a class member of type
InternalSystem.Collections.Generic.List<INode>. The AOT fails on the
callvirt for InternalSystem.Collections.Generic.List<INode>::get_Count.
The IL of the method (compiled with VS2005) is:
.maxstack 2
.locals init (
[0] int32 i,
[1] class SharpOS.Kernel.VFS.INode device,
[2] class SharpOS.Kernel.VFS.INode CS$1$0000,

L_0042: ldnull
L_0043: stloc.2
L_0044: br.s L_0046
L_0046: ldloc.2
L_0047: ret
The failure is on the CIL instruction on line L_0037. I have no clue how to
fix this one, I haven't looked into the register allocation.

This is a known problem, generics haven't been fully implemented yet.
