Roman Levenstein e326332acd Use a linked data structure for the uses lists of an SDNode, just like ... LLVM Value/Use does and MachineRegisterInfo/MachineOperand does. This allows constant time for all uses list maintenance operations. The idea was suggested by Chris. Reviewed by Evan and Dan. Patch is tested and approved by Dan. On normal use-cases compilation speed is not affected. On very big basic blocks there are compilation speedups in the range of 15-20% or even better. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48822 91177308-0d34-0410-b5e6-96231b3b80d8		2008-03-26 12:39:26 +00:00
