[LLVMdev] Asserts in bundleWithPred() and bundleWithSucc()
...#6 ... in llvm::finalizeBundle (MBB=..., FirstMI=..., LastMI=...) at
...lib/CodeGen/MachineInstrBundle.cpp:112
Let me give you another example though. I have the following existing
bundle:
v BUNDLE %R0<imp-def,dead>, %PC<imp-def>, %R18<imp-use>
*^v %R0<def> = AND_ri %R18, 128
*^ JMP_EQriPnt_nv_V4 %R0<kill,internal>, 0, <BB#2>, %PC<imp-def>
I need to move an instruction into this bundle from another location and
insert it _between_ AND_ri and JMP_EQriPnt_nv_V4. I use MBB->splice(...) to
do that. Let's pretend that moved instruction...

The intention was to identify code that may have been converted from the old style a

[LLVMdev] Asserts in bundleWithPred() and bundleWithSucc()
Jakob,
I have a question about the following (four) asserts recently added in
bundleWithPred() and bundleWithSucc() (see below). What is the real danger
of reasserting a connection even if it already exist? My problem with them
happens when I try to call finalizeBundle() on an existing bundle to which I
have added a new instruction. The goal - a new bundle header with liveness
abbreviation, but
