* Use a simpler data structure to calculate the least recently used register ↵Jakob Stoklund Olesen2010-04-161-112/+41

* The JIT calls TidyLandingPads to tidy up the landing pads. However, because theBill Wendling2010-04-165-8/+22
| | | | | | | | | | | | | | | | | JIT doesn't use the MC back-end asm printer to emit labels that it uses, the section for the MCSymbol is never set. And thus the MCSymbol for the EH label isn't marked as "defined". Because of that, TidyLandingPads removes the needed landing pads from the JIT output. This breaks EH for every JIT program. This is a work-around for this limitation. We pass in the label locations map. If the label has a non-zero value, then it was "emitted" by the JIT and TidyLandingPads shouldn't remove that label. A nicer solution would be to mark the MCSymbol as "used" by the JIT and not rely upon the section being set to determine if it's defined or not. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101453 91177308-0d34-0410-b5e6-96231b3b80d8
