llvm dev - Apr 2012 - [LLVMdev] How to dump a .bc file before/after a specific opt pass?

Hi, all. I'm adding a new pass in opt. To make the debugging easier, I'm
trying to
draw the CFG before and after the new pass. Is there any an option to dump
the
.bc file before/after a specific opt pass? Thanks.

Hi,

If you're using `opt`, you can use -print-module to dump the module.
So "opt -S file.ll -print-module -your-opt -print-module", or
something
like that.
