This package includes some tools to visualize the LLVM IR. Current
visualizations include static call graphs, CFGs, CDGs, dominator
trees, and some simple escape graphs. Output formats include most
graphviz-supported formats, along with an HTML-based format.
# Usage
Options for the visualizer:
-o --output=[FILE or DIR] The destination of a file output
-t --type=[GRAPHTYPE] The graph requested. One of Cfg, Cdg, Cg,
Domtree, Postdomtree
-f --format=GVOUT The type of output to produce: Gtk, Xlib, Html, XDot,
Eps, Jpeg, Pdf, Png, Ps, Ps2, Svg. Default: Gtk
-? --help Display help message
For all graph types except the call graph, the output specifies a
*directory*. The directory will contain one output file for each
function in the input IR module. For the static call graph, the
output is a single file. If the format is 'Html', the output is
always a directory.
The Html format is special. It produces an SVG embedded in an HTML
page. The SVG can be navigated (via panning and zooming) using an
openstreetmap-style interface (it uses the OpenLayers library).
Input files can be LLVM bitcode files, LLVM assembly files, or C/C++ source
files.
# Dependencies
This package depends on a few other Haskell libraries that are not yet
on Hackage:
* hbgl
* haggle
* ifscs
* llvm-base-types
* llvm-data-interop
* llvm-analysis
Additionally, it requires that you have the LLVM shared libraries (versions
3.0-3.2) and tools installed on your system (`llvm-config` must be in your
`PATH`).
# Installation
Installation would look something like:
```bash
REPOSITORIES="hbgl-experimental
haggle
ifscs
itanium-abi
llvm-base-types
llvm-data-interop
llvm-analysis
llvm-tools"
# Download the repositories
for REPO in $REPOSITORIES
do
git clone git://github.com/travitch/$REPO.git
done
# Add ./ prefixes to each repository (for cabal)
TOINSTALL=`echo ./$REPOSITORIES | sed 's: : ./:g'`
# Build the tools along with dependencies
cabal install $TOINSTALL
```
