If we do a delegate call that translates to a static call, the delegate pointer that was passed needs to be skipped and we need to pass the actual arguments. However, the following arguments might not come immediately after the delegate pointer, if the first argument is simd aligned. Pass this information to MINT_CALL_DELEGATE so the correct offset of the arguments can be computed.

Fixes#92925

Previous code was checking if we should have already pushed a dreg, to compute the correct position of the argument on the stack. Save pointer to args directly instead.

This is actually a fix for a regression from .net7, so it is a backport candidate, which can be reproduced with a trivial sample:

using System;
using System.Runtime.Intrinsics;
public class Program {
public static void Method (Vector128<int> v)
{
Console.WriteLine (v);
}
public static void Main (string[] args)
{
Vector128<int> v = Vector128.Create (1, 2, 3, 4);
Action<Vector128<int>> act = Method;
act (v);
}
}

On .net8 rc1 this prints <1711280944, 32733, 1, 2>

@matouskozak could you take a look at the extra platforms failures to see if everything looks ok ?

If we do a delegate call that translates to a static call, the delegate pointer that was passed needs to be skipped and we need to pass the actual arguments. However, the following arguments might not come immediately after the delegate pointer, if the first argument is simd aligned. Pass this information to MINT_CALL_DELEGATE so the correct offset of the arguments can be computed.

Fixes#92925

Previous code was checking if we should have already pushed a dreg, to compute the correct position of the argument on the stack. Save pointer to args directly instead.

This is actually a fix for a regression from .net7, so it is a backport candidate, which can be reproduced with a trivial sample:

using System;
using System.Runtime.Intrinsics;
public class Program {
public static void Method (Vector128<int> v)
{
Console.WriteLine (v);
}
public static void Main (string[] args)
{
Vector128<int> v = Vector128.Create (1, 2, 3, 4);
Action<Vector128<int>> act = Method;
act (v);
}
}

On .net8 rc1 this prints <1711280944, 32733, 1, 2>

@matouskozak could you take a look at the extra platforms failures to see if everything looks ok ?
