Chris Lattner af17096dcf 3 Changes: 1. Better document what is going on here. 2. Only hack on one branch per iteration, making the results less conservative. 3. Handle the problematic case by marking edges executable instead of by playing with value lattice states. This is far less pessimistic, and fixes SCCP/ipsccp-gvar.ll. llvm-svn: 31106	2006-10-22 05:59:17 +00:00
