Hey @fanyang-mono could this #88101 be related to the failing tests?

[fanyang-mono]

No, it shouldn't be. That PR changed the behavior of SpanHelpers, not Vector128 itself.

[fanyang-mono]

Are they only failing on windows?

[ivanpovazan]

@vargaz I have verified that the regressions on win-x64 started occurring with: ac2d3fb

The problem seems to be related to the change on this line: ac2d3fb#diff-012b47a27abc5dbc9d2a0b6fdef4adec27fa207a7d2b53823a8bc80f6539f5afR2384
which changed the behaviour of Vector128<T>.IsSupported intrinsic on win-x64 platforms to always return false even for supported type parameters used with generic Vector128.

There are two groups of tests failing because of this:

• all IsSupported tests returning false, for otherwise supported type parameter types
• all tests relying on .AsNInt() or .AsNUInt() throwing System.NotSupportedException: Specified type is not supported because internally these extension methods call
