Alkis Evlogimenos e88280a422 Add option to join live intervals. Two intervals are joined if there ... is a move between two registers, at least one of the registers is virtual and the two live intervals do not overlap. This results in about 40% reduction in intervals, 30% decrease in the register allocators running time and a 20% increase in peephole optimizations (mainly move eliminations). The option can be enabled by passing -join-liveintervals where appropriate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10965 91177308-0d34-0410-b5e6-96231b3b80d8		2004-01-22 23:08:45 +00:00
