Getting source line numbers from within a Pass?

Project Infrastructure LLVM Dev List Archives

Hi, I would like to get at the source line number(s) that a BasicBlock
is generated from, and the only interface I see to this info in the
code is from the debugger.

After sifting through that, I think I might be able to do what I want
by finding dbg_stoppoint intrinsics, but I'm not sure how to get to
them. And, if there's an easy way, that'd be cool to know about.

Also, I cant seem to produce an LLVM assembly file with the stoppoints
visible. Do I need to do anything special to see them?

Thanks,

Yup, the only way to get them is through the debugger intrinsics.

them. And, if there's an easy way, that'd be cool to know about.

Unfortunately, we do not have a front-end that produces the intrinsics
yet. :frowning: Adding them to the C frontend would probably be pretty easy
though if you're interested in tackling the project. Note that 'easy' is
relative to any hacking on GCC...

I'm not sure what you mean here. You can't write one by hand, or you
can't get the CFE to produce one?
