IdealGraphVisualizer: the context menu of graph nodes includes submenus for predecessors and successors. Recursively building them ahead of time can incur heavy delays even with limited recursion depth. Instead, build these menus on demand, i.e. when the user opens a particular submenu.

For creating a Graal VM JDK, the file jre\lib\jvm.cfg has to be modified such that it includes the line: -graal KNOWN Before running the Graal VM, the following environment variables is needed: - MAXINE: Pointing to a Maxine VM repository with compiled Java files. In particular, the VM will look for the compiled Java files in the following directories: ${MAXINE}/com.oracle.max.cri/bin ${MAXINE}/com.oracle.max.base/bin ${MAXINE}/com.oracle.max.asmdis/bin ${MAXINE}/com.oracle.max.asm/bin ${MAXINE}/com.oracle.max.graal.graph/bin ${MAXINE}/com.oracle.max.graal.compiler/bin ${MAXINE}/com.oracle.max.graal.nodes/bin ${MAXINE}/com.oracle.max.graal.extensions/bin ${MAXINE}/com.oracle.max.graal.runtime/bin ${MAXINE}/com.oracle.max.graal.graphviz/bin For starting the Graal VM, the flag "-graal" has to be specified. Additional flags that might be useful: -G:Plot Sends the graphs of compiled methods via network stream to the IdealGraphVisualizer (NetBeans project at ${GRAAL}/src/share/tools/IdealGraphVisualizer that can be built and run with NetBeans 7.0, use "Graal Coloring" and "Graal Edge Coloring" filters) -G:Time Prints timings for the different compilation phases -G:Meter Prints metrics for the different compilation phases The usual HotSpot flags -Xcomp -XX:CompileOnly= -XX:CompileCommand= or -XX:+PrintCompilation can be used to control the compiled methods.
