From 4b8f36f10672bbdd747eabfb5708e4758c3d5337 Mon Sep 17 00:00:00 2001 From: Devang Patel Date: Tue, 29 Aug 2006 22:29:16 +0000 Subject: Do not rely on std::sort and std::erase to get list of unique exit blocks. The output is dependent on addresses of basic block. Add and use Loop::getUniqueExitBlocks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29966 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Transforms/Scalar/LoopUnswitch.cpp | 14 ++++---------- 1 file changed, 4 insertions(+), 10 deletions(-) (limited to 'lib/Transforms/Scalar/LoopUnswitch.cpp') diff --git a/lib/Transforms/Scalar/LoopUnswitch.cpp b/lib/Transforms/Scalar/LoopUnswitch.cpp index 9c3655205b..ea643b698e 100644 --- a/lib/Transforms/Scalar/LoopUnswitch.cpp +++ b/lib/Transforms/Scalar/LoopUnswitch.cpp @@ -570,11 +570,8 @@ void LoopUnswitch::UnswitchNontrivialCondition(Value *LIC, Constant *Val, LoopBlocks.insert(LoopBlocks.end(), L->block_begin(), L->block_end()); std::vector ExitBlocks; - L->getExitBlocks(ExitBlocks); - std::sort(ExitBlocks.begin(), ExitBlocks.end()); - ExitBlocks.erase(std::unique(ExitBlocks.begin(), ExitBlocks.end()), - ExitBlocks.end()); - + L->getUniqueExitBlocks(ExitBlocks); + // Split all of the edges from inside the loop to their exit blocks.
