From dc303126ff480903c83d393e430bf37302350359 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Mon, 21 Apr 2008 04:22:09 +0000 Subject: enable jump threading pass by default. This causes no miscompilations and can significantly shrinkify some code, particularly from C++ land. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50025 91177308-0d34-0410-b5e6-96231b3b80d8 --- tools/opt/opt.cpp | 1 + 1 file changed, 1 insertion(+) (limited to 'tools/opt') diff --git a/tools/opt/opt.cpp b/tools/opt/opt.cpp index ca206cf..4b7dbf5 100644 --- a/tools/opt/opt.cpp +++ b/tools/opt/opt.cpp @@ -267,6 +267,7 @@ void AddStandardCompilePasses(PassManager &PM) { addPass(PM, createTailDuplicationPass()); // Simplify cfg by copying code addPass(PM, createInstructionCombiningPass()); // Cleanup for scalarrepl. + addPass(PM, createJumpThreadingPass()); // Thread jumps. addPass(PM, createCFGSimplificationPass()); // Merge & remove BBs addPass(PM, createScalarReplAggregatesPass()); // Break up aggregate allocas addPass(PM, createInstructionCombiningPass()); // Combine silly seq's -- cgit v1.1
