[llvm-dev] Line number without -Debug ?

[Irini Stavrakantonaki via llvm-dev]

Is this "work" heavier than enabling the debug mode?

Nop. No XY question here. In fact it is just be more useful for me to 
have the information of line number but still be in release mode.
(if this is possible or in other words less "painful" for my pass)

Thanks
