2009-07-11assert(0) -> LLVM_UNREACHABLE.Torok Edwin
Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75379 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-13Change class' public PassInfo variables to by initialized with theDan Gohman
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
2008-05-13Clean up the use of static and anonymous namespaces. This turned upDan Gohman

2007-05-02Use 'static const char' instead of 'static const int'.Devang Patel
Due to darwin gcc bug, one version of darwin linker coalesces static const int, which defauts PassID based pass identification. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36652 91177308-0d34-0410-b5e6-96231b3b80d8

2005-08-13Teach SplitCriticalEdge to update LoopInfo if it is alive. This fixesChris Lattner
a problem in LoopStrengthReduction, where it would split critical edges then confused itself with outdated loop information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22776 91177308-0d34-0410-b5e6-96231b3b80d8
2005-08-12Change break critical edges to not remove, then insert, PHI node entries.Chris Lattner
Instead, just update the BB in-place. This is both faster, and it prevents split-critical-edges from shuffling the PHI argument list unneccesarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22765 91177308-0d34-0410-b5e6-96231b3b80d8
