| | | | | | | | | | | | | | | | | | Constant uniquing tables. This allows distinct ConstantExpr objects with the same operation and different flags. Even though a ConstantExpr "a + b" is either always overflowing or never overflowing (due to being a ConstantExpr), it's still necessary to be able to represent it both with and without overflow flags at the same time within the IR, because the safety of the flag may depend on the context of the use. If the constant really does overflow, it wouldn't ever be safe to use with the flag set, however the use may be in code that is never actually executed. This also makes it possible to merge all the flags tests into a single test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80998 91177308-0d34-0410-b5e6-96231b3b80d8

* Revert the addition of hasNoPointerOverflow to GEPOperator.Dan Gohman2009-07-201-18/+0
| | | | | | | | | | | | | Getelementptrs that are defined to wrap are virtually useless to optimization, and getelementptrs that are undefined on any kind of overflow are too restrictive -- it's difficult to ensure that all intermediate addresses are within bounds. I'm going to take a different approach. Remove a few optimizations that depended on this flag. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76437 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a new Operator class, for handling Instructions and ConstantExprsDan Gohman2009-07-171-0/+132
in a convenient manner, factoring out some common code from InstructionCombining and ValueTracking. Move the contents of BinaryOperators.h into Operator.h and use Operator to generalize them to support ConstantExprs as well as Instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76232 91177308-0d34-0410-b5e6-96231b3b80d8
