[llvm-dev] Manually insert an instruction in SelectionDAG

[Lorenzo Casalino via llvm-dev]

As far as I know, up to the CodeGen phase, LLVM works on a
target-agnostic representation of the original code; low
level concepts, such as ASM directives, are not handled; thus, it is not
possible to add them in the SelectionDAG or
in the subsequent machine specific representation.

As pointed out by Tim, you could print them during the code emission
phase [1].
