IRView

What it does

A quickly way to visualize callgraph, control flow graph, regions, ... of LLVM Intermediate Representation files on Sublime Text.

But -view-* passes already does that, no?

Yes but those passes never worked with me.

Which passes are supported by IRView?

• callgraph
• cfg (-only)
• dom (-only)
• postdom (-only)
• regions (-only)
