2008-05-29Replace the old ADCE implementation with a new one that more simply solvesOwen Anderson
the one case that ADCE catches that normal DCE doesn't: non-induction variable loop computations. This implementation handles this problem without using postdominators. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51668 91177308-0d34-0410-b5e6-96231b3b80d8

like. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51662 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-28Add a flag to indicate that an instruction is as cheap (or cheaper) than a moveBill Wendling
instruction to execute. This can be used for transformations (like two-address conversion) to remat an instruction instead of generating a "move" instruction. The idea is to decrease the live ranges and register pressure and all that jazz. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51660 91177308-0d34-0410-b5e6-96231b3b80d8

slightest attempt at some renumbering logic, which is currently unused. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51652 91177308-0d34-0410-b5e6-96231b3b80d8
