Note regarding the new-api-needs-documentation label:

This serves as a reminder for when your PR is modifying a ref *.cs file and adding/modifying public APIs, please make sure the API implementation in the src *.cs file is documented with triple slash comments, so the PR reviewers can sign off that change.

I can reproduce. The crash appears unrelated to that specific test, the addition of the new LoadVectorX tests triggers it.

vargaz · 2023-10-04T02:55:54Z

Also, according to the test output:
Supported ISAs:
AdvSimd: False

The new tests are not even supposed to run.

Also, according to the test output: Supported ISAs: AdvSimd: False

Wondering why AdvSimd: False on linux-arm64 Release leg?

The new tests are not even supposed to run.

That's right, it crashed while trying to run RunUnsupportedScenario().

I can reproduce. The crash appears unrelated to that specific test, the addition of the new LoadVectorX tests triggers it.

I am assuming this PR cannot be merged until we fix this issue. Are you planning to submit a fix in this PR?

AdvSimd is only supported on mono when running with llvm, not with the mono JIT.

Tracking this down will take some time. Would be nice to be able to disable this on mono, but I don't see any such functionality in GenerateHWIntrinsicTests_Arm.cs.

The problem seems to be in the DataTable class in the tests:

            public DataTable({Op1BaseType}[] outArray1, {Op1BaseType}[] outArray2, {Op1BaseType}[] inArray, int alignment)
            {
                int sizeOfInArray = inArray.Length * Unsafe.SizeOf<{Op1BaseType}>();
                int sizeOfOutArray1 = outArray1.Length * Unsafe.SizeOf<{Op1BaseType}>();
                int sizeOfOutArray2 = outArray2.Length * Unsafe.SizeOf<{Op1BaseType}>();
                if ((alignment != 16 && alignment != 8) || (alignment * 2) < sizeOfInArray || (alignment * 2) < sizeOfOutArray1 || (alignment * 2) < sizeOfOutArray2)
                {
                    throw new ArgumentException("Invalid value of alignment");
                }

                this.inArray = new byte[alignment * 2];
                this.outArray1 = new byte[alignment * 2];
                this.outArray2 = new byte[alignment * 2];

                this.inHandle = GCHandle.Alloc(this.inArray, GCHandleType.Pinned);
                this.outHandle1 = GCHandle.Alloc(this.outArray1, GCHandleType.Pinned);
                this.outHandle2 = GCHandle.Alloc(this.outArray2, GCHandleType.Pinned);

                this.alignment = (ulong)alignment;

                Unsafe.CopyBlockUnaligned(ref Unsafe.AsRef<byte>(inArrayPtr), ref Unsafe.As<{Op1BaseType}, byte>(ref inArray[0]), (uint)sizeOfInArray);
            }

            public void* inArrayPtr => Align((byte*)(inHandle.AddrOfPinnedObject().ToPointer()), alignment);

If inArray is not 16 byte aligned, then the copy done by Unsafe.CopyBlockUnaligned () can write out of the bounds of the array, causing random crashes. This affects all the LoadVectorxTest.template files. A fix would be to bump the
multiplier (i.e. 2 -> 3, 3 -> 4, 4 -> 5) in
this.inArray = new byte[alignment * 2];

I am not sure why this is not problem for other test cases.

LGTM. Just a request to update the documentation for LoadVector equivalent.
