  Hi Aries. Thanks very much! Precisely this is the situation! There're two consecutive branches (br1cond and br2uncond). Inside of AnalyzeBranch, there's an opcode swap of br2uncond (ex. j_foward to j_backward). There I do BuildMI (newOpcode) and followed by br2uncond->eraseFromParent(). This results in br1cond loosing it's label/offset. How could I resolve this? Best regards, Girish.

Hello All. On a particular target the back-end generates an instruction like: beqz      r2, "$BB0_-1"   Is it a back-end specific issue? Could someone please help me figure out how this gets resolved? What confuses me is, all other branches are correctly labelled and resolved!  Thanks. Girish. -------------- next part -------------- An HTML attachment was scrubbed... URL:
