Hi, It was reported that Fedora 38 Clang does not run correctly under qemu-s390x [1]. Comparing qemu and real s390x instruction traces has shown that the implementations of LCBB and LOCFHR were not fully correct.
This series fixes the issues and adds tests. I can now run Fedora 38 Clang under s390x emulation and compile "hello world" with it.
