* Remove the API for creating ConstantExprs with the nsw, nuw, inbounds,Dan Gohman2009-09-039-92/+22
| | | | | | | | | | | | | | | | and exact flags. Because ConstantExprs are uniqued, creating an expression with this flag causes all expressions with the same operands to have the same flag, which may not be safe. Add, sub, mul, and sdiv ConstantExprs are usually folded anyway, so the main interesting flag here is inbounds, and the constant folder already knows how to set the inbounds flag automatically in most cases, so there isn't an urgent need for the API support. This can be reconsidered in the future, but for now just removing these API bits eliminates a source of potential trouble with little downside. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80959 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | Add or Remove operation complete, and not while building the intermediate tree. This trades a little bit more memory usage for less accesses to the FoldingSet. On a benchmark for the clang static analyzer, this shaves off another 13% of execution time when using field/array sensitivity. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80955 91177308-0d34-0410-b5e6-96231b3b80d8

* Overhaul the TwoAddressInstructionPass to simplify the logic, especiallyBob Wilson2009-09-031-159/+210
| | | | | | | | | | | | | | | | | | for the complicated case where one register is tied to multiple destinations. This avoids the extra scan of instruction operands that was introduced by my recent change. I also pulled some code out into a separate TryInstructionTransform method, added more comments, and renamed some variables. Besides all those changes, this takes care of a FIXME in the code regarding an assumption about there being a single tied use of a register when converting to a 3-address form. I'm not aware of cases where that assumption is violated, but the code now only attempts to transform an instruction, either by commuting its operands or by converting to a 3-address form, for the simple case where there is a single pair of tied operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80945 91177308-0d34-0410-b5e6-96231b3b80d8
