From 23d471f62eed3518fe7737dbccee52faec4ffe75 Mon Sep 17 00:00:00 2001 From: Torok Edwin Date: Sun, 24 May 2009 09:31:04 +0000 Subject: [PATCH] Add -disable-global-remove option to bugpoint. Sometimes when bugpointing a crash the bugpoint-reduced-simplified.bc reproduces a totally different bug than the original one ("GV doesn't have initializer"). Although its useful to report that bug too, I need a way to reduce the original bug, hence I introduced -disable-global-remove. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72361 91177308-0d34-0410-b5e6-96231b3b80d8 --- tools/bugpoint/CrashDebugger.cpp | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/tools/bugpoint/CrashDebugger.cpp b/tools/bugpoint/CrashDebugger.cpp index 4225a40c743..2e43f88c711 100644 --- a/tools/bugpoint/CrashDebugger.cpp +++ b/tools/bugpoint/CrashDebugger.cpp @@ -37,6 +37,10 @@ namespace { KeepMain("keep-main", cl::desc("Force function reduction to keep main"), cl::init(false)); + cl::opt + NoGlobalRM ("disable-global-remove", + cl::desc("Do not remove global variables"), + cl::init(false)); } namespace llvm { @@ -344,7 +348,8 @@ bool ReduceCrashingBlocks::TestBlocks(std::vector &BBs) { static bool DebugACrash(BugDriver &BD, bool (*TestFn)(BugDriver &, Module *)) { // See if we can get away with nuking some of the global variable initializers // in the program... - if (BD.getProgram()->global_begin() != BD.getProgram()->global_end()) { + if (!NoGlobalRM && + BD.getProgram()->global_begin() != BD.getProgram()->global_end()) { // Now try to reduce the number of global variable initializers in the // module to something small.
