[LLVMdev] LLVM Dependency Graph

Based on cmake/modules/LLVMLibDeps.cmake, I produced a graphviz dot file and
then manually removed components and edges until the graph was small enough to
be presentable. I don't know if I can actually use LLVM due to its
humongousness, but I hope the graph will be helpful to others attempting to
comprehend LLVM. PNG attached; dot file follows.

This is really cool.  Do you have a script that produces the .dot file?  If so,
we could check it in and add a makefile target,

CMake has that feature built-in:

cmake --graphviz=foo.dot path/to/llvm/root

The graph isn't very pretty, but it can be processed with some tool to
fancify it, as explained on this blog post:
