Debugging Graal on JDK 9

[Andrew Haley]

Thanks everybody!

I'm getting closer:

mercury:graal-core $  JVMCI_VERSION_CHECK=ignore mx -d vm  -XX:+UseJVMCICompiler -XX:-PrintCompilation -XX:CompileCommandFile=.hotspot_compiler -cp ~ FloatTest
/local/mercury/local/graal/graal-core/mxbuild/modules/com.oracle.graal.graal_core.pickled does not exist

This is JDK9, built today from jdk9/hs.

Without JVMCI_VERSION_CHECK=ignore I get

The VM does not support the minimum JVMCI API version required by Graal.
Cannot read JDK9 EA build number from java.vm.version property: 9-internal+0-2016-10-19-140336.aph.hs.
Set the JVMCI_VERSION_CHECK environment variable to "ignore" to suppress this error or to "warn" to emit a warning and continue execution.
Currently used Java home directory is /local/mercury/local/hs/build/linux-x86_64-normal-server-release/images/jdk.
Currently used VM configuration is: OpenJDK 64-Bit Server VM
