* InstCombine: Fix infinite loop when encountering switch on trivial icmp.Benjamin Kramer2012-05-28
The test case feeds the following into InstCombine's visitSelect: %tobool8 = icmp ne i32 0, 0 %phitmp = select i1 %tobool8, i32 3, i32 0 Then instcombine replaces the right side of the switch with 0, doesn't notice that nothing changes and tries again indefinitely. This fixes PR12897. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157587 91177308-0d34-0410-b5e6-96231b3b80d8
