Changes in directory llvm/lib/CodeGen:
BranchFolding.cpp updated: 1.30 -> 1.31 DwarfWriter.cpp updated: 1.91 -> 1.92 ELFWriter.cpp updated: 1.26 -> 1.27 LiveInterval.cpp updated: 1.35 -> 1.36 LiveIntervalAnalysis.cpp updated: 1.187 -> 1.188 LiveVariables.cpp updated: 1.60 -> 1.61 --- Log message: For PR786: http://llvm.org/PR786 : Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting fall out by removing unused variables. Remaining warnings have to do with unused functions (I didn't want to delete code without review) and unused variables in generated code. Maintainers should clean up the remaining issues when they see them. All changes pass DejaGnu tests and Olden. --- Diffs of the changes: (+1 -7) BranchFolding.cpp | 2 -- DwarfWriter.cpp | 1 - ELFWriter.cpp | 1 - LiveInterval.cpp | 1 - LiveIntervalAnalysis.cpp | 2 +- LiveVariables.cpp | 1 - 6 files changed, 1 insertion(+), 7 deletions(-) Index: llvm/lib/CodeGen/BranchFolding.cpp diff -u llvm/lib/CodeGen/BranchFolding.cpp:1.30 llvm/lib/CodeGen/BranchFolding.cpp:1.31 --- llvm/lib/CodeGen/BranchFolding.cpp:1.30 Wed Nov 1 13:36:29 2006 +++ llvm/lib/CodeGen/BranchFolding.cpp Thu Nov 2 14:25:49 2006 @@ -766,7 +766,6 @@ // Analyze the branch at the end of the pred.
