Description Filip Pizlo 2015-04-14 15:53:18 PDT
Currently we keep things that are dead-in-DFG alive for OSR by using Phantoms. Phantoms are fine as a backend hack in the DFG, but they are really hard to preserve soundly through serious compiler transformations. We should rationalize this so that we have fewer bugs to fix.
