You can dump the MIR after each pass with -mllvm -print-after-all. Look 
for "Prologue/Epilogue Insertion".

Here is the LangRef equivalent for MIR: http://llvm.org/docs/MIRLangRef.html.

If you find anything unclear don’t hesitate to put a patch up and add me as a
reviewer, I’ll be happy to help!

You can also use -print-after=prologepilog for the specific pass, or even llc
-stop-after=prologepilog to dump a MIR file that can be re-parsed by llc
-start-after=prologepilog.
