...live intervals. It is only added as a requirement to make sure it runs before the 2-address pass. -Andy Thank you for your reply. I do it as you tell me, and you are right. My update steps are shown following: LiveIntervals *LIS = &getAnalysis<LiveIntervals>(); 1. LIS->insertMBBInMaps(NewMBB) 2. LIS->InsertMachineInstrRangeInMaps(NewMBB->begin(), NewMBB->end()) 3. Due to some machine instructions of NewMBB copy from OldMBB, I have to removeInterval firstly. Then I use LIS->createAndComputeVirtRegInterval() to update LiveInterval info of NewMBB. 4. Then I...

Hi, I insert a new machine basic block(MBB) before Greedy Register Allocation, after Simple Register Coalescing. But I encounter a fatal error "regalloc = ... not currently supported with -O0". I use command line with opt level O2, not O0. The probable reason of this error is that no LiveInterval information for newly MBB which is used by Register Allocation. And, LiveIntervals depend
