[LLVMdev] Bug in MachineRegisterInfo ?
Hi, I wanted to see the non-debug uses of register 0 (Noreg) and so, I wrote the following piece of code. ***** MRI = &MF.getRegInfo(); if (!MRI->use_nodbg_empty(0)) { for (MachineRegisterInfo::use_nodbg_iterator ri = MRI->use_nodbg_begin(0), re = MRI->use_nodbg_end(); ri != re; ++ri) { MachineInstr *UseMI = &*ri; UseMI->dump (); } } ***** But I see that UseMI is DBG_VALUE %noreg, 0, !"foobar"; line no:511 inlined @[ foo.cc:364:5 ] Also, w...

[LLVMdev] Assert in LiveInterval update
Hi Lang, Just one more quick question. in LiveIntervalAnalysis.cpp In SlotIndex findLastUseBefore(unsigned Reg, SlotIndex OldIdx) Did you really mean to use for (MachineRegisterInfo::use_nodbg_iterator UI = MRI.use_nodbg_begin(Reg), UE = MRI.use_nodbg_end(); UI != UE; UI.skipInstruction()) {} Aren't we currently dealing with units, not registers ? SlotIndex LastUse = findLastUseBefore(LI->reg, OldIdx); .and isn't MRI.use_nodbg_begin(Reg)...

[LLVMdev] Assert in LiveInterval update
Hi Sergei, Andy, Sorry - I got distracted with some other work. I'm looking into this and PR13719 now. I'll let you know what I find out. Sergei - thanks very much for the investigation. That should help me pin this down. Cheers, Lang. On Tue, Aug 28, 2012 at 2:33 PM, Sergei Larin <slarin at codeaurora.org> wrote: > Andy, Lang, > > Thanks for the suggestion. >

[LLVMdev] Assert in LiveInterval update
Andy, Lang, Thanks for the suggestion. I have spent more time with it today, and I do see some strange things in liveness update. I am not at the actual cause yet, but here is what I got so far: I have the following live ranges when I start scheduling a region: R2 = [0B,48r:0)[352r,416r:5)... R3 = [0B,48r:0)[368r,416r:5)... R4 = [0B,32r:0)[384r,416r:4)... R5 = [0B,32r:0)[400r,416r:4)...
