[llvm-dev] How to get the symbol of MachineInst ?

[John Reagan via llvm-dev]

The MachineInst will be lowered into an MCInst by
lib/Target/X86/X86MCInstLower.cpp.
There isn't an MCSymbol for it.

If you want to record the address of an instruction, you'll have to
create labels in before them in the lowering
with CreateTempSymbol() & EmitLabel() and then use EmitSymbolValue().
