Rafael Espindola 2548391104 Move early tail duplication earlier. ... This fixes the issue noted in PR10251 where early tail dup of bbs with indirectbr would cause a bb to be duplicated into a loop preheader and then into its predecessors, creating phi nodes with identical operands just before register allocation. This helps with jsinterp.o size (__TEXT goes from 163568 to 126656) and a bit with performance 1.005x faster on sunspider (jits still enabled). The result on webkit with the jit disabled is more significant: 1.021x faster. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134372 91177308-0d34-0410-b5e6-96231b3b80d8		2011-07-04 04:54:22 +00:00
