2009-11-16	Fixes the bug exposed by Anton's test case in PR 5495:	Lang Hames
	Make sure when ProcessImplicitDefs removes a copy which kills its source reg that it removes the copy from said reg's Kills list. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@88881 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-03	The Indexes Patch.	Lang Hames
	This introduces a new pass, SlotIndexes, which is responsible for numbering instructions for register allocation (and other clients). SlotIndexes numbering is designed to match the existing scheme, so this patch should not cause any changes in the generated code. For consistency, and to avoid naming confusion, LiveIndex has been renamed SlotIndex. The processImplicitDefs method of the LiveIntervals analysis has been moved into its own pass so that it can be run prior to SlotIndexes. This was necessary to match the existing numbering scheme. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85979 91177308-0d34-0410-b5e6-96231b3b80d8
