<pre>$ clang -g foo.ll
... should add debug information, pointing back to the .ll file, in the same
way that
$ clang -g foo.s
... already adds debug information pointing back to the relevant line in the .s
file. This would make it possible to perform "source"-level single-step
debugging through llvm IR in the user's debugger of choice. (And for
optimizations that properly preserve debug information, would allow a limited
amount of mapping from optimized IR back into the original IR.)</pre>
