```

Start with the hotspot_compiler target in extended.openjdk and reproduce the six failures on JDK23 riscv. Read the listed jdk.vm.ci.code.test files and the stack through CodeInstallationTest.java:121, especially the “nmethod entry barrier is missing” failure. Done means the six named tests pass on the affected configuration.
