I am now trying to get the trace of AbstractVector.castShape.

Akira1Saitoh commented 2 years ago

It seems either of JIT compiled Byte128Vector.slice(int) or AbstractVector.convert0(char, AbstractSpecies) has a problem.

https://github.com/ibmruntimes/openj9-openjdk-jdk18/blob/0c89bcfb32934a82973a74b49c726382ae98f552/src/jdk.incubator.vector/share/classes/jdk/incubator/vector/AbstractVector.java#L371

            int origin = shapeChangeOrigin(vsp, rsp, true, part);
            //System.out.println("*** origin = "+origin+", part = "+part+", lanewise");
            if (part > 0) {  // Expansion: slice first then cast.
                return slice(origin).convert0(kind, rsp);
            } else {  // Contraction: cast first then unslice.
Akira1Saitoh commented 2 years ago

It seems Byte128Vector.slice(int) returns zero vector. In ByteVector.sliceTemplate(int), mask for blending is created but this happens to be all false mask when the test fails.

https://github.com/ibmruntimes/openj9-openjdk-jdk18/blob/9bdb9425c548ea2917c5b79ecbb5788b86314c00/src/jdk.incubator.vector/share/classes/jdk/incubator/vector/ByteVector.java#L2173

        VectorMask<Byte> blendMask = iota.toVector().compare(VectorOperators.LT, (broadcast((byte)(length() - origin))));
