Chris Lattner 82bec2cff0 Substantially refactor the SCCP class into an SCCP pass and an SCCPSolver ... class. The only changes are minor: * Do not try to SCCP instructions that return void in the rewrite loop. This is silly and fool hardy, wasting a map lookup and adding an entry to the map which is never used. * If we decide something has an undefined value, rewrite it to undef, potentially leading to further simplications. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17816 91177308-0d34-0410-b5e6-96231b3b80d8		2004-11-15 04:44:20 +00:00
