Done: Removed the addition of a new C2 Node, merged the macro assembler encode_iso_array and encode_ascii_array and added a predicate to select the behavior. > It also needs to be implemented and tested on all architectures. Implementing this on other hardware is Future Work. The non-x86 intrinsics for implEncodeISOArray all seem to use clever tricks rather than a simple mask that can be easily switched from detecting non-latin-1(0xFF00) to detecting ASCII (0xFF80). Clever tricks make it rather challenging to extend this like I could easily do in the x86 code (most all assembler is foreign to me) ------------- PR: https://git.openjdk.java.net/jdk/pull/5621
