@dean-long I've added your commits on top of the PR, and added an additional commit to include https://github.com/openjdk/jdk/pull/18642#discussion_r1560900520. I've run compiler tests limiting to C1 on x86_64 and things looked good. I didn't test other architectures because the additional changes were limited to the shared code.
