I just checked in a new analyze pass that may be useful for people...
which converts the CFG of a function into a graph for easy printing or
visualization. Since I thought this might be useful for other people
using LLVM, I thought I'd tell you all about it.
Basically do this:
analyze -print-cfg foo.bc
This will cause a bunch of 'dot' files to be written to the disk (one for
each function). Using the 'dot' tool
(http://www.research.att.com/sw/tools/graphviz/), you can convert these to
a variety of formats, including postscript. Just do:
dot -Tps < cfg.main.dot > cfg.main.ps
to make a postscript file out of the CFG for 'main'. If you're on our
research machines, you can use my install of dot, which is here:
