Well man.
I'm just poli****ng YARDstick and taking care of the legalese. It is a
major project of mine that measures up to ~25klines of code for now,
not to mention the external BSD-licensed libraries it uses.
I can't understand your attitude though. A great automation is not
va****, but you are.
YARDstick was presented at DATE'07 this April. Some guys from the
MORPHEUS project as well as a senior researcher from Synopsys had a
good look on the tool and its Tcl/Tk 8.5.a5 GUI.
Maybe you should ask MORPHEUS people, they have witnessed it.
Here follows part of my answer to the other post.
Check out a custom instruction from an edge detection filter. It has
been auto-identified and auto-dumped.

Graphviz dump:

14 -> 6;
3 -> 2 [label="vr228.s32"];
2 -> 1 [label="vr229.s32"];
1 -> 0 [label="vr230.s32"];
6 -> 5 [label="vr231.s32"];
5 -> 4 [label="vr232.s32"];
4 -> 0 [label="vr233.s32"];
}
Just copy-paste the stuff and use Graphviz (dot) and VCG to view
them.
