From 2c235010312f72622acd4b7bb70f87cf31a982f6 Mon Sep 17 00:00:00 2001 From: Torok Edwin Date: Sun, 24 May 2009 09:40:47 +0000 Subject: [PATCH] Make bugpoint emit a bugpoint-reduced-blocks.bc, because bugpoint itself can crash during instruction simplification (for example if it creates a broken module). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72362 91177308-0d34-0410-b5e6-96231b3b80d8 --- tools/bugpoint/CrashDebugger.cpp | 3 +++ 1 file changed, 3 insertions(+) diff --git a/tools/bugpoint/CrashDebugger.cpp b/tools/bugpoint/CrashDebugger.cpp index 2e43f88c711..f46fed78608 100644 --- a/tools/bugpoint/CrashDebugger.cpp +++ b/tools/bugpoint/CrashDebugger.cpp @@ -426,7 +426,10 @@ static bool DebugACrash(BugDriver &BD, bool (*TestFn)(BugDriver &, Module *)) { E = BD.getProgram()->end(); I != E; ++I) for (Function::const_iterator FI = I->begin(), E = I->end(); FI !=E; ++FI) Blocks.push_back(FI); + unsigned OldSize = Blocks.size(); ReduceCrashingBlocks(BD, TestFn).reduceList(Blocks); + if (Blocks.size() < OldSize) + BD.EmitProgressBitcode("reduced-blocks"); } // FIXME: This should use the list reducer to converge faster by deleting
