8 For starting the Graal VM, the two flags "-client -graal" have to be specified. | 8 In particular, the VM will look for the compiled Java files in the following directories: |
9 ${MAXINE}/com.oracle.max.cri/bin | |
10 ${MAXINE}/com.oracle.max.base/bin | |
11 ${MAXINE}/com.oracle.max.asmdis/bin | |
12 ${MAXINE}/com.oracle.max.asm/bin | |
13 ${MAXINE}/com.oracle.max.graal.graph/bin | |

19 -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) | |
20 -G:Time Prints timings for the different compilation phases | |
21 -G:Meter Prints metrics for the different compilation phases | |

23 The usual HotSpot flags -Xcomp -XX:CompileOnly= -XX:CompileCommand= or -XX:+PrintCompilation can be used to control the compiled methods. |
