When looking into the documentation for the other two bugs which I just confirmed/filed, I noticed that we still document the life passes dump option but the life pass was removed when dataflow branch was merged in: -fdump-rtl-cfg -fdump-rtl-life -fdump-rtl-cfg enable dumping after control and data flow analysis, to file.116r.cfg. -fdump-rtl-cfg enable dumping dump after life analysis, to file.128r.life1 and file.135r.life2.
