From 3ed469ccd7b028a030b550d84b7336d146f5d8fa Mon Sep 17 00:00:00 2001 From: Reid Spencer Date: Thu, 2 Nov 2006 20:25:50 +0000 Subject: For 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31380 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Transforms/Scalar/LoopUnswitch.cpp | 7 ++----- 1 file changed, 2 insertions(+), 5 deletions(-) (limited to 'lib/Transforms/Scalar/LoopUnswitch.cpp') diff --git a/lib/Transforms/Scalar/LoopUnswitch.cpp b/lib/Transforms/Scalar/LoopUnswitch.cpp index 95217254bd..a91d295540 100644 --- a/lib/Transforms/Scalar/LoopUnswitch.cpp +++ b/lib/Transforms/Scalar/LoopUnswitch.cpp @@ -576,8 +576,6 @@ void LoopUnswitch::UnswitchNontrivialCondition(Value *LIC, Constant *Val, // Split all of the edges from inside the loop to their exit blocks.
