This fixes a bug where IndVars was holding on to a stale insertion point and forcing the SCEVExpander to continue to use it.

* SCEVExpander's InsertCastOfTo knows how to move existing castDan Gohman2009-04-222-0/+29
| | | | | | | | | | | | instructions in order to avoid inserting new ones. However, if the cast instruction is the SCEVExpander's InsertPt, this causes subsequently emitted instructions to be inserted near the cast, and not at the location of the original insert point. Fix this by adjusting the insert point in such cases. This fixes PR4009. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69808 91177308-0d34-0410-b5e6-96231b3b80d8

* It has finally happened. Spiller is now using live interval info.Evan Cheng2009-04-217-43/+96
| | | | | | | This fixes a very subtle bug. vr defined by an implicit_def is allowed overlap with any register since it doesn't actually modify anything. However, if it's used as a two-address use, its live range can be extended and it can be spilled. The spiller must take care not to emit a reload for the vn number that's defined by the implicit_def. This is both a correctness and performance issue. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@69743 91177308-0d34-0410-b5e6-96231b3b80d8
