@Hamlin-Li Can you describe your general approach with https://github.com/openjdk/jdk/pull/28230? How exactly will you deal with the type size change? Will you have a conversion of the mask, between the comparison and the blend? It may be good if you describe it in a bit of detail, so that we can allow `aarch64` and `x64` specialists to look at it, and see if the basic design is platform independent enough ;)
