It creates the jdk.vm.ci.riscv64 and jdk.vm.ci.hotspot.riscv64 packages, as well as implements a part of jvmciCodeInstaller_riscv64.cpp. To check for correctness, it enables JVMCI code installation tests on RISC-V. It should be tested soon in GraalVM Native Image as well.

Hi, I see some JVM crash when I try the following test with fastdebug build with your patch:
    test/hotspot/jtreg/compiler/jvmci/jdk.vm.ci.code.test/src/jdk/vm/ci/code/test/SimpleDebugInfoTest.java
