Bug. Native AOT .NET 7.0 doesn't work. System.NotSupportedException: X86Serialize

[Avangardum]

I created a very simple benchmark:

[SimpleJob(RuntimeMoniker.NativeAot70)]
public class Benchmarks
{
    [Benchmark]
    public void Foo()
    {
        Thread.Sleep(5);
    }
}

When I run it, I get the following output:

Hi @Avangardum

Could you please share your project file?

[Avangardum]

Hello, @adamsitnik.

I uploaded the whole solution https://github.com/Avangardum/BenchmarkDotNetBugReproduction

[adamsitnik]

@Avangardum thanks for sharing the repro.

It works on my machine:

BenchmarkDotNet v0.13.10, Windows 11 (10.0.22621.2428/22H2/2022Update/SunValley2)
AMD Ryzen Threadripper PRO 3945WX 12-Cores, 1 CPU, 24 logical and 12 physical cores
.NET SDK 9.0.100-alpha.1.23531.2
  [Host]        : .NET 7.0.13 (7.0.1323.51816), X64 RyuJIT AVX2
  NativeAOT 7.0 : .NET 7.0.11-servicing.23424.27, X64 NativeAOT AVX2

Job=NativeAOT 7.0  Runtime=NativeAOT 7.0

| Method | Mean     | Error    | StdDev   |
|------- |---------:|---------:|---------:|
| Foo    | 16.56 ms | 0.171 ms | 0.160 ms |

Could you please apply the following attribute:

[SimpleJob(RuntimeMoniker.NativeAot70)]
+ [KeepBenchmarkFilesAttribute]
public class Benchmarks

And share the "IlcInstructionSet" part of BenchmarkDotNetBugReproduction\bin\Release\net7.0\NativeAOT 7.0\BenchmarkDotNet.Autogenerated.csproj

Here is mine:

<IlcInstructionSet>base,sse,sse2,sse3,ssse3,sse4.1,sse4.2,avx,avx2,aes,bmi,bmi2,fma,lzcnt,pclmul,popcnt</IlcInstructionSet>

@MichalStrehovsky Do you have any idea why using X86Serialize fails with an exception for @Avangardum ? It works fine on my machine, however I am using newer SDK.

[MichalStrehovsky]

#2463 (comment) has serialize as an instruction set specified. This cannot be set on .NET 7 due to a bug (whoever was adding the instruction set forgot to add AOT handling). This bug was fixed in dotnet/runtime@c81e83a#diff-65f20fbb1fbd6c815168e9d3b2b358c4fd02aea226f2152099427a594310b876R114. It's fixed in .NET 8.

[adamsitnik]

@Avangardum the bug got fixed, you can either wait until 0.13.11 gets shipped to nuget.org (2 weeks from now) or try latest version from our preview feed: https://benchmarkdotnet.org/articles/guides/nuget.html?q=nuget#nightly
