* Add an option to always emit realignment code for a particular module.Eric Christopher2010-08-052-1/+55

* Be more aggressive about removing joined physreg copies.Jakob Stoklund Olesen2010-08-051-3/+10
| | | | | | | When a joined COPY changes subreg liveness, we keep it around as a KILL, otherwise it is safe to delete. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@110403 91177308-0d34-0410-b5e6-96231b3b80d8
* Don't verify LiveVariables if LiveIntervals is available.Jakob Stoklund Olesen2010-08-051-12/+13
| | | | | | | | LiveVariables becomes horribly wrong while the coalescer is running, but the analysis is not zapped until after the coalescer pass has run. This causes tons of false reports when calling verify form the coalescer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@110402 91177308-0d34-0410-b5e6-96231b3b80d8

* Add basic verification of LiveIntervals.Jakob Stoklund Olesen2010-08-051-0/+59
| | | | | | | | | | | | | | We verify that the LiveInterval is live at uses and defs, and that all instructions have a SlotIndex. Stuff we don't check yet: - Is the LiveInterval minimal? - Do all defs correspond to instructions or phis? - Do all defs dominate all their live ranges? - Are all live ranges continually reachable from their def? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@110386 91177308-0d34-0410-b5e6-96231b3b80d8
