Furnace X-Ray
Furnace X-Ray is a visualizer for transformations performed on Static Single Assignment form in the Furnace framework.
Installation
$ gem install furnace-xray
Usage
First, you need to enable instrumentation for the functions you want to observe. Here is a sample snippet:
mod = SSA::Module.new
fun = SSA::Function.new('my-function')
# It is important to enable instrumentation before doing anything else
# with the function. Otherwise, the collected data will be invalid.
fun.instrumentaiton = SSA::EventStream.new
mod.add fun
# Optionally, notify the instrumentation engine that you have started
# a transformation.
fun.instrumentation.transform_start "Set return type"
# Now, do whatever you want with the function.
fun.return_type = SSA.void_type
# After you have finished transforming functions, fetch the instrumentation
# data and dump it as JSON.
File.write("data.json", JSON.dump(mod.instrumentation))To view collected data, just point furnace-xray to it:
$ furnace-xray data.json
