Also, can you explain in the bug how you start the devtools, and how they appear, maybe I would manage to reproduce this issue. Otherwise, if you have time I suggest we discuss on irc.mozilla.org (nbp) on how to instrument the code to debug this addon.

Thanks Liam Wilson On Wednesday, June 10, 2015 at 9:58:26 PM UTC+1, Nicolas B. Pierron wrote: Hello everybody, I am please to do an early announce a new tool named Jit DevTools. This new tool is an addon which mostly target Jit developers. It uses the recently added Debugger.onIonCompilation hook to display the latest MIR [1] and LIR graphs within the dev tools. To use this tool, go to a web page, and open the Jit DevTools panel, then wait until a function got compiled. Once a function is compiled, you can select a compiled script, which will display the MIR graph of the compilation. If you need to, you can also have a look at the LIR graph. The output is similar to the one rendered with iongraph [5]. By selecting any inlined script, the background of the block titles will change color, if the block correspond to the inlined instance. This feature is quite useful to identify how a function plays in a compiled script. You might find this tool quite handy to use for the following use cases: - Investigating DOM optimization. - Investigating jsperf issues. - Comparing function implementations, and impacts on the generated code. This addon works on optimized builds, and even with parallel compilation enabled. You can download [2] this early version from http://people.mozilla.org/~npierron/jit-dev-tools/ , or build it your-self by using the sources [3] with jpm tool [4]. Have fun, and enjoy.
