Dear all, I'd like to find the memory location of certain instructions in a compiled/linked binary. During the IR phase, I tag instructions I'm interested in with LLVM'-2.7's new metadata (MDNodes with an identifiable ID). I'd now like to propagate that data to the assembly via a custom DWARF tag I attach to each X86 instruction created from a tagged IR instruction. This will
