I'm getting an Instruction emitter crash when emitting an INLINEASM SDNode that is Glued to other nodes.
The crash happens at line 808 of file llvm/lib/CodeGen/SelectionDAG/InstrEmitter.cpp:
const MCInstrDesc &MCID = TII->get(F->getMachineOpcode());
with the assertion:
assert(isMachineOpcode() && "Not a MachineInstr opcode!");
I'm not a great expert of the instruction emitter part unfortunately, but I tried to track down the problem and I managed to fix it for my case (now the instruction emitter outputs the InlineAsm correctly without crashes and the inlined code is in the assembly output).
I attached the patch with this email.
The regression tests pass, but if someone more expert on that code could tell me if I'm doing something wrong I'd appreciate
