JDK-8283091 - Support type conversion between different data sizes in SLP
Description
Current C2's SLP vectorizer doesn't support type conversion operations. But AArch64 has vector type conversion instructions (in both NEON and SVE). So it should possible to enable these by adding some support in the mid-end and/or back-end.
