Jakob Stoklund Olesen 01582996dd Fix liveness calculation when splitting critical edges during PHI elimination. ... - Edges are split before any phis are eliminated, so the code is SSA. - Create a proper IR BasicBlock for the split edges. - LiveVariables::addNewBlock now has same syntax as MachineDominatorTree::addNewBlock. Algorithm calculates predecessor live-out set rather than successor live-in set. This feature still causes some miscompilations. llvm-svn: 86867		2009-11-11 19:31:31 +00:00
