[LLVMdev] Instruction Emitter crash when emitting glued InlineAsm SDNode

[Marcello Maggioni]

Hi,

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 :)

Cheers,
Marcello
