[Crossgen2 CI] Interop PInvoke Generics Vector tests failing in R2R outerloop on windows-x86

[github-actions]

Failure Details

• Pipeline: runtime-coreclr crossgen2 outerloop
• Build: 1388564
• Configuration: windows x86, R2R Pri1 checked
• Error Category: test-failure

Failing Tests

Test Name	Platform	Error Type
global::GenericsTest.TestVector128C()	windows-x86	test-failure
global::GenericsTest.TestVector256C()	windows-x86	test-failure
global::GenericsTest.TestVector64C()	windows-x86	test-failure
global::GenericsTest.TestVectorC()	windows-x86	test-failure

These tests exercise P/Invoke interop with Vector128<char>, Vector256<char>, Vector64<char>, and Vector<char> generic types via native GenericsNative DLL imports.

Cross-Reference

These failures do not appear in the runtime pipeline — they are specific to R2R (crossgen2) mode on windows x86 in the outerloop Pri1 configuration.

Recommended Action

This failure requires deeper investigation into how crossgen2 pre-compiles generic SIMD Vector P/Invoke interop code on x86. Please disable the failing tests by adding [ActiveIssue] attributes:

• Test source files:
  • src/tests/Interop/PInvoke/Generics/GenericsTest.Vector128C.cs
  • src/tests/Interop/PInvoke/Generics/GenericsTest.Vector256C.cs (if exists)
  • src/tests/Interop/PInvoke/Generics/GenericsTest.Vector64C.cs (if exists)
  • src/tests/Interop/PInvoke/Generics/GenericsTest.VectorC.cs (if exists)
• Project: src/tests/Interop/Interop.csproj
• Add [ActiveIssue("https://github.com/jtschuster/runtime/issues/ISSUE_NUMBER")] to the TestVector128C, TestVector256C, TestVector64C, and TestVectorC test methods
• Target R2R mode on windows x86 if possible
