Hi I'm seeing something probably related to this. I'm getting an assert from the lower_bound in LiveIntervals::findLiveinMBBs (from a checking std:: VS2005 implementation). Idx2MBBMap has two elements in it, both of which have a .first of 0. (I believe because of an empty MBB in the function below, so StartIndex doesn't advance). scott On Wed, Apr 16, 2008 at 2:52 AM, Roman Levenstein <romixlev at yahoo.com>...

...bug so I don't forget? I'm a little occupied right now. But I'll take care of this soon.

...if (!Reg) continue; // Ignore splited live intervals. if (!isPhys && vrm_->getPreSplitReg(cur.reg)) continue; for (LiveInterval::Ranges::const_iterator I = cur.begin(), E = cur.end(); I != E; ++I) { const LiveRange &LR = *I; if (li_->findLiveInMBBs(LR.start, LR.end, LiveInMBBs)) { for (unsigned i = 0, e = LiveInMBBs.size(); i != e; ++i) if (LiveInMBBs[i] != EntryMBB) LiveInMBBs[i]->addLiveIn(Reg); LiveInMBBs.clear(); } } } If it is the case, it is OK. It was not clear for me that one has...

Hi, In the LiveIntervalAnalysis::runOnMachineFunction, there is a code to compute the MBB2IdxMap, by remembering for each MBB its start and end instruction numbers: unsigned MIIndex = 0; for (MachineFunction::iterator MBB = mf_->begin(), E = mf_->end(); MBB != E; ++MBB) { unsigned StartIdx = MIIndex; for (MachineBasicBlock::iterator I = MBB->begin(), E =
