Chris Lattner 0770d8e326 Preserve and update ETForest. Patch by Daniel Berlin 
llvm-svn: 25203
 2006-01-11 05:11:13 +00:00
Chris Lattner 89c1dfc733 Teach SplitCriticalEdge to update LoopInfo if it is alive. This fixes 
a problem in LoopStrengthReduction, where it would split critical edges
then confused itself with outdated loop information.

Chris Lattner b7ebe65c56 Change break critical edges to not remove, then insert, PHI node entries. 
Instead, just update the BB in-place.  This is both faster, and it prevents
split-critical-edges from shuffling the PHI argument list unneccesarily.

Chris Lattner bf3a099a62 Updates to work with recent Statistic's changes: 
* 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.

Chris Lattner bedbd6bc16 - Cleanup break-crit-edges pass by making SplitCriticalEdge a member method. 
- break-crit-edges pass does not invalidate loop-preheader pass.

Chris Lattner 75f80bd0b6 - Do not expose Critical Edge breaking mechanics outside the BCE pass, thus 
removing it from Transforms/Local.h and from Transforms/Utils/*

Chris Lattner 4bec665b09 - Expose passinfo from BreakCriticalEdges pass so that it may be "Required" 
by other passes.  Make BCE pass be in anonymous namespace now.
