* Change class' public PassInfo variables to by initialized with theDan Gohman2008-05-131-1/+1
| | | | | | | | | | | | address of the PassInfo directly instead of calling getPassInfo. This eliminates a bunch of dynamic initializations of static data. Also, fold RegisterPassBase into PassInfo, make a bunch of its data members const, and rearrange some code to initialize data members in constructors instead of using setter member functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51022 91177308-0d34-0410-b5e6-96231b3b80d8

* Move SplitBlockPredecessors out of loopsimplify into BasicBlockUtils.hChris Lattner2008-04-211-107/+14
| | | | | | | | | | as a global helper function. At the same type, switch it from taking a vector of predecessors to an arbitrary sequential input. This allows us to switch LoopSimplify to use a SmallVector for various temporary vectors that it passed into SplitBlockPredecessors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50020 91177308-0d34-0410-b5e6-96231b3b80d8
