Jim Laskey	9d4209fb82	1. Add a pass to fold debug label instructions so a debug info client can detect ... empty ranges. 2. Reorg how MachineDebugInfo maintains changes to debug labels. 3. Have dwarf writer use debug label info to simplify scopes and source line coorespondence. 4. Revert the merging of compile units until I can get the bugs ironed out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31507 91177308-0d34-0410-b5e6-96231b3b80d8	2006-11-07 19:33:46 +00:00

Chris Lattner	4a84ad7a2b	add the branch folding pass as a late cleanup pass for all targets. For now ... it just deletes empty MBB's. Soon it will do more :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30941 91177308-0d34-0410-b5e6-96231b3b80d8	2006-10-13 20:45:56 +00:00
