2008-05-21Fix PR2343. An *interesting* coalescer bug.Evan Cheng
BB1: vr1025 = copy vr1024 .. BB2: vr1024 = op = op vr1025 <loop eventually branch back to BB1> Even though vr1025 is copied from vr1024, it's not safe to coalesced them since live range of vr1025 intersects the def of vr1024. This happens when vr1025 is assigned the value of the previous iteration of vr1024 in the loop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51394 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-21Fix a couple issues with the JIT and multiple modules:Nate Begeman
1. The "JITState" object creates a PassManager with the ModuleProvider that the jit is created with. If the ModuleProvider is removed and deleted, the PassManager is invalid. 2. The Global maps in the JIT were not invalidated with a ModuleProvider was removed. This could lead to a case where the Module would be freed, and a new Module with Globals at the same addresses could return invalid results. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51384 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-21When LSR is replacing an instruction, callDan Gohman
ScalarEvolution::deleteValueFromRecords on it before doing the replaceAllUsesWith, because ScalarEvolution looks at the instruction's users to find SCEV references to the instruction's SCEV object in its internal maps. Move all of LSR's loop-related state clearing after processing the loop and before cleaning up dead PHI nodes. This eliminates all of LSR's SCEV references just before the calls to ScalarEvolution::deleteValueFromRecords so that when ScalarEvolution drops its own SCEV references, the reference counts will reach zero and the SCEVs will be deleted immediately. These changes fix some compiler aborts involving ScalarEvolution holding onto and reusing SCEV objects for instructions that have been deleted. No regression test unfortunately; because the symptoms were due to dangling pointers, reduced testcases ended up being fairly arbitrary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51359 91177308-0d34-0410-b5e6-96231b3b80d8
