Bill Wendling 8370d38ade Add a flag to indicate that an instruction is as cheap (or cheaper) than a move ... 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		2008-05-28 22:54:52 +00:00
