Not sure I follow - why would you want to drop line/column info? Isn't that relevant to the inlining stack - you might have multiple calls in the same function & it'd be good to know which one the diagnostic is referring to. > The DISubprogram and DILocation should form a similar chain, even if > significantly more complicated to "unwind."
