  Hello, I am trying to clone a machine basic block when I ran into some issues, where I am not able to make some headway. Any of yours help is highly appreciated here: My question is about Machine Basic Block Duplication:   -          Is there a utility to clone a MachineBasicBlock in LLVM? I found utility to clone machineInstrs, but couldn’t find similar utility for MachineBasicBlock. So, I

...live interval end is 257 while %reg1330's interval start is 258. The merging code expects them to be equal in this case where the source register is dead after the copy. If we look at another copy where the source is dead but was NOT spilled, we see something different: Examining copy 420%reg1057 = MOV64rr %reg1297<kill> MOV64rr %reg1057<d> %reg1297 Ok from regalloc Real regs %reg1057 = %reg1297 Intervals: %reg1057,0 = [422,1034:0) 0 at 422-(1034) %reg1297,0 = [402,420:0)[420,422:1)[1074,1096:2) 0 at 402-(421) 1@?-(422) 2 at 1074-(1095) Notice how the end of the second valu...
