Hi all, I ran across an assertion failure while using region analysis in my passes. I get the same thing when doing: opt -regions -analyze [...] [1] entry => if.end End region tree Printing analysis 'Detect single entry single exit regions' for function 'njDecodeSOF': Region tree: [0] entry => <Function Return> [1] entry => return [2] if.end => return [3] if.end6 => return [4] sw.epilog => return [5] for.cond => return [6] if.end62 => if.end69 [6] if.end69 => if.end75 [6] for.end => if.end81 [6] for.cond88 => return [7] for.end143 => return End region tree opt: /home/towelie/Tools/LLVM/llvm/lib/Analysis/RegionInfo.cpp:86: bool llvm::Region::contains(const llvm::BasicBlock *) const: Assertion `DT->getNode(BB) && "BB not part of the dominance tree"' failed. 0 opt 0x0000000000bc715e 1 opt 0x0000000000bc765a 2 libpthread.so.0 0x00007fe7ed96d420 3 libc.so.6 0x00007fe7ed17cb45 gsignal + 53 4 libc.so.6 0x00007fe7ed17dfc6 abort + 390 5 libc.so.6 0x00007fe7ed1758ce 6 libc.so.6 0x00007fe7ed175990 __assert_perror_fail + 0 7 opt 0x0000000000921a70 llvm::Region::contains(llvm::BasicBlock const*) const + 96 8 opt 0x0000000000921f2e llvm::Region::getExitingBlock() const + 142 9 opt 0x0000000000921fd9 llvm::Region::isSimple() const + 73 10 opt 0x00000000009244dc llvm::RegionInfo::updateStatistics(llvm::Region*) + 44 11 opt 0x0000000000924657 llvm::RegionInfo::createRegion(llvm::BasicBlock*, llvm::BasicBlock*) + 327 12 opt 0x0000000000924766 llvm::RegionInfo::findRegionsWithEntry(llvm::BasicBlock*, llvm::DenseMap<llvm::BasicBlock*, llvm::BasicBlock*, llvm::DenseMapInfo<llvm::BasicBlock*> >*) + 246 13 opt 0x00000000009248c0 llvm::RegionInfo::scanForRegions(llvm::Function&, llvm::DenseMap<llvm::BasicBlock*, llvm::BasicBlock*, llvm::DenseMapInfo<llvm::BasicBlock*> >*) + 208 14 opt 0x0000000000924d6c llvm::RegionInfo::Calculate(llvm::Function&) + 60 15 opt 0x0000000000924e7c llvm::RegionInfo::runOnFunction(llvm::Function&) + 204 16 opt 0x0000000000b4548a llvm::FPPassManager::runOnFunction(llvm::Function&) + 442 17 opt 0x0000000000b4578d llvm::FPPassManager::runOnModule(llvm::Module&) + 125 18 opt 0x0000000000b459dd llvm::MPPassManager::runOnModule(llvm::Module&) + 493 19 opt 0x0000000000b46097 llvm::PassManagerImpl::run(llvm::Module&) + 167 20 opt 0x0000000000b46281 llvm::PassManager::run(llvm::Module&) + 33 21 opt 0x00000000005502cb main + 6491 22 libc.so.6 0x00007fe7ed1692ad __libc_start_main + 253 23 opt 0x000000000053fa85 Stack dump: 0.

Hi , It will be good ,If you get us the sample that assert.
