| 222 | 1 The Ideal Graph Visualizer is a tool developed to help examine the |
| 2 intermediate representation of C2 which is commonly referred to as the | |
| 3 "ideal graph". It was developed in collaboration with the University | |
| 4 of Linz in Austria and has been included as part of hotspot since that | |
| 5 was the primary target of the tool. The tool itself is fairly general | |
| 6 with only a few modules that contain C2 specific elements. | |

8 The tool is built on top of the NetBeans 7 rich client |
| 222 | 9 infrastructure and so requires NetBeans to build. It currently |
| 10 requires Java 6 to run as it needs support for JavaScript for its | |
| 11 filtering mechanism and assumes it's built into the platform. It | |

12 should build out of the box with NetBeans 7.0 and Java 6 or later. |
| 222 | 13 |
| 14 The JVM support is controlled by the flag -XX:PrintIdealGraphLevel=# | |
| 15 where # is: | |
| 16 | |
| 17 0: no output, the default | |
| 18 1: dumps graph after parsing, before matching, and final code. | |
| 19 also dumps graph for failed compiles, if available | |
| 20 2: more detail, including after loop opts | |
| 21 3: even more detail | |
| 22 4: prints graph after parsing every bytecode (very slow) | |
| 23 | |
| 24 By default the JVM expects that it will connect to a visualizer on the | |
| 25 local host on port 4444. This can be configured using the options | |
| 26 -XX:PrintIdealGraphAddress= and -XX:PrintIdealGraphPort=. | |
| 27 PrintIdealGraphAddress can actually be a hostname. | |
| 28 | |
| 29 Alternatively the output can be sent to a file using | |
| 30 -XX:PrintIdealGraphFile=filename. Each compiler thread will get it's | |
| 31 own file with unique names being generated by adding a number onto the | |
| 32 provided file name. | |
