First of all, I am new to MacOS, and what I want is to be able to see the output of llc -view-dag-combine1-dags sum.ll. On Mac, llc will generate dot in /tmp directory, and try open App to show the dot file. I have tried Graphviz, but it doesn't work (the program crash). I would like try something else, like xdot for example. I install it by brew install xdot, but don't know how to let the MacOS use the xdot I just installed to open the dot file.

Or any other better tool to view the dot file? I would like to keep thing as simple as possible.

I never used 'llc' before.

But in my case to deal with the .dot file

I used brew install graphviz

Then used the following command to convert .dot to .png

dot -Tpng DocName.dot -o DocName.png

It works every time without crash.
