Changes in directory llvm/lib/Analysis:
AliasAnalysis.cpp updated: 1.28 -> 1.29 BasicAliasAnalysis.cpp updated: 1.80 -> 1.81 LoopInfo.cpp updated: 1.69 -> 1.70 PostDominators.cpp updated: 1.56 -> 1.57 ValueNumbering.cpp updated: 1.18 -> 1.19 --- Log message: For PR780: http://llvm.cs.uiuc.edu/PR780 : 1. Fix the macros in IncludeFile.h to put everything in the llvm namespace 2. Replace the previous explicit mechanism in all the .h and .cpp files with the macros in IncludeFile.h This gets us a consistent mechanism throughout LLVM for ensuring linkage. Next step is to make sure its used in enough places. --- Diffs of the changes: (+11 -14) AliasAnalysis.cpp | 6 +----- BasicAliasAnalysis.cpp | 6 +++--- LoopInfo.cpp | 5 +++-- PostDominators.cpp | 5 ++--- ValueNumbering.cpp | 3 ++- 5 files changed, 11 insertions(+), 14 deletions(-) Index: llvm/lib/Analysis/AliasAnalysis.cpp diff -u llvm/lib/Analysis/AliasAnalysis.cpp:1.28 llvm/lib/Analysis/AliasAnalysis.cpp:1.29 --- llvm/lib/Analysis/AliasAnalysis.cpp:1.28 Wed Jun 7 15:00:19 2006 +++ llvm/lib/Analysis/AliasAnalysis.cpp Wed Jun 7 17:00:26 2006 @@ -188,8 +188,4 @@ // be pulled in if the AliasAnalysis classes are pulled in.
