几个DHE问题(2)

[AlanLiu90]

环境

Unity	2020.3.33
il2cpp_plus	2020-DHE
hybridclr	DHE
hybridclr_unity	DHE
OS+Build	Windows 10 64 bit
project	dhe_demo (没开间接函数优化)

问题1

计算等价性时，报错：

NullReferenceException: Object reference not set to an instance of an object
HybridCLR.Editor.DHE.MethodCompareCache.CompareExceptionHandler (dnlib.DotNet.Emit.ExceptionHandler e1, dnlib.DotNet.Emit.ExceptionHandler e2) (at Library/PackageCache/com.focus-creative-games.hybridclr_unity@8c290d286c/Editor/DHE/MethodCompareCache.cs:590)

复现代码：

class A
{
    private object mLock = new object();

    public void Func1()
    {
        lock (mLock)
        {
            var e = Func2();
            if (e != null)
                throw e;

            throw new InvalidOperationException("xxxx");
        }
    }

    private Exception Func2()
    {
        return null;
    }
}

问题2

没有变化的函数，被计算为不等价，复现代码：

class A<T> where T : UnityEngine.Object
{
    private UnityEngine.Object mObject;

    public A(UnityEngine.Object obj)
    {
        mObject = obj;
    }

    public T Object
    {
        get
        {
            return mObject as T;
        }
    }
}

输出：change mehtod:T A`1::get_Object() token:100663298

问题3

多线程情况下，GetRuntimeMetadataIl2CppType中，可能创建多个相同的dhType

问题4

s_dheTypes在il2cpp::vm::GlobalMetadata::Clear中没有释放

我们处理一下

1-4均已经修复，分别更新 hybridclr_unity和 il2cpp_plus即可

il2cpp_plus没有看到更新，请确认下
