[QUESTION]: Is it available to compile a Dynamic Method with ILGPU?

Question

I need to run a method created dynamically.

DynamicMethod dm=new DynamicMethod("Test", typeof(void),new Type[]{typeof(Index1D),typeof(ArrayView<Single>)},typeof(Program));
var il= dm.GetILGenerator();
il.Emit(OpCodes.Ret);
var del=dm.CreateDelegate<Action<Index1D,ArrayView<float>>>();
/*
equals to:

static void Test(
        Index1D index,ArrayView<float> buffer)  // A view of floats to store float results from GPUMath
    {
        return;
    }

*/
using var context = Context.CreateDefault();
using var accelerator = context.GetPreferredDevice(preferCPU: true).CreateAccelerator(context);
var kernel = accelerator.LoadAutoGroupedStreamKernel(del);
using var buffer = accelerator.Allocate1D<float>(128);
kernel((int)buffer.Length, buffer.View);

However, exception System.NotSupportedException: Derived classes must provide an implementation. takes place.
Is there any way to compile a dynamically created method with ILGpu?
And there's no "Derived classes" I think

Environment

• ILGPU version: 1.5.3
• .NET version: 10
• Operating system: Windows10
• Hardware (if GPU-related): this problem may not be related to hardware

hi @jyswjjgdwtdtj

Unfortunately no, DynamicMethod does not provide a way for ILGPU to retrieve the underlying MSIL code. Is there a particular reason you need to use DynamicMethod? Can a non-capturing lambda be used instead?

I implemented a series of methods to handle a data type that I customized. And I use DynamicMethod to compile it.
I think it's really possible to achieve it, maybe ilgpu can have a special ILGenerator to record the IL.

I found that the GPU was not able to perform effectively for a large batch of operations at a time like mine.
