        Description

        AOT compiled code always assumes r27 is the heap base pointer, but since JDK-8242449 C2 can allocate it as a general register if the compressed class base is null.

        To reproduce:

        make test TEST="compiler/aot/cli/jaotc/CompileModuleTest.java" JTREG="VM_OPTIONS=-Xcomp -XX:-TieredCompilation"
