This patch creates a new option in DEBUG builds of Tamarin-Tracing. By having both the -Dtrees and -Ddraw_trees enabled, the trace trees which were compiled will be drawn into the .graphml format. You can compare the resulting picture to the output of -Dstats. The results can be viewed by loading the resulting .graphml file. The .graphml file is located in /path/to/testfile/yourTestFile.abc.graphml. You can view the resulting graph with YED (http://www.yworks.com/en/products_yed_about.html).

Once the .graphml file has been loaded in YED, do the following steps to make it prettier.
1) In the menu bar, go to Tools->Fit Node To Label
2) Then menu bar->Layout->Hierarchical->classic.
3) Push ok







Reproducible: Always

Steps to Reproduce:
1. Build avmplus with a DEBUG build
2. Run test file with BOTH flags -Dtrees and -Ddraw_trees
