You are right, I was thinking about the case where you have 2 short variables, you should combine them into a long explicitly for C2 to generate a 4-byte write, otherwise it would be 2 2-bytes. Omitted the constant part which already eliminates this restriction. ------------- PR Comment: https://git.openjdk.org/jdk/pull/19626#issuecomment-2158743190
