* Improve APInt interface:Reid Spencer2007-02-272-55/+67
| | | | | | | | | | | 1. Add unsigned and signed versions of methods so a "bool" argument doesn't need to be passed in. 2. Make the various getMin/getMax functions all be inline since they are so simple. 3. Simplify sdiv and srem code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34680 91177308-0d34-0410-b5e6-96231b3b80d8

* For PR1205:Reid Spencer2007-02-271-14/+5
| | | | | | | | | | | | Implement review feedback: 1. Use new APInt::RoundDoubleToAPInt interface to specify the bit width so that we don't have to truncate or extend in constant folding. 2. Fix a pasteo in SDiv that prevented a check for overflow. 3. Fix the shift operators: undef happens when the shift amount is equal to the bitwidth. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34677 91177308-0d34-0410-b5e6-96231b3b80d8
