2003-02-27Add a new assertion to check that stuff is happening rightChris Lattner
Ironically the exit block modification code wasn't updating the exit block information itself. Fix this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5659 91177308-0d34-0410-b5e6-96231b3b80d8
2003-02-27 * Don't forget to update Loop information!Chris Lattner
* Remove bogus assertion: there may be a single outside predecessor and still need a new loop-preheader if the predecessor has multiple successors. See bug: LICM/2003-02-27-PreheaderProblem.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5655 91177308-0d34-0410-b5e6-96231b3b80d8
2003-02-27 * Significant changes to the preheader insertion pass:Chris Lattner
- Now we perform loop exit-block splitting to ensure exit blocks are always dominated by the loop header. - We now preserve dominance frontier information - This fixes bug: LICM/2003-02-26-LoopExitNotDominated.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@5652 91177308-0d34-0410-b5e6-96231b3b80d8
2002-10-01Updates to work with recent Statistic's changes:Chris Lattner
* Renamed StatisticReporter.h/cpp to Statistic.h/cpp * Broke constructor to take two const char * arguments instead of one, so that indendation can be taken care of automatically. * Sort the list by pass name when printing * Make sure to print all statistics as a group, instead of randomly when the statistics dtors are called. * Updated ProgrammersManual with new semantics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4002 91177308-0d34-0410-b5e6-96231b3b80d8
