Changes in directory llvm/include/llvm:
GlobalValue.h updated: 1.33 -> 1.34 --- Log message: Rework GlobalValue::removeDeadConstantUsers to always remove dead constant exprs hanging off a global, even if the global is not otherwise dead. This requires some tricky iterator gymnastics. This implements Transforms/GlobalOpt/constantexpr-dangle.ll by deleting a constantexpr that made it appear that the address of the function was taken. --- Diffs of the changes: (+0 -4) GlobalValue.h | 4 ---- 1 files changed, 4 deletions(-) Index: llvm/include/llvm/GlobalValue.h diff -u llvm/include/llvm/GlobalValue.h:1.33 llvm/include/llvm/GlobalValue.h:1.34 --- llvm/include/llvm/GlobalValue.h:1.33 Sun Feb 11 23:18:08 2007 +++ llvm/include/llvm/GlobalValue.h Sun Feb 25 15:06:13 2007 @@ -128,10 +128,6 @@ /// off of this global value, remove them.
