I have a vague recollection that this column info hack was added to disambiguate two types defined on the same line (which is something that happened more often than one would think because of macro expansion). Did you do the git archeology to ensure that the original reason for doing it this way has been resolved? FWIW, I'm fine with doing this change for the Darwin platforms because column info is turned on by default, so this shouldn't affect us.<br></blockquote><div><br>It was (I think) duplicate calls (rather than types) - so that inlining (which previously didn't produce a unique'd inlinedAt location (because we didn't have the "unique" metadata feature)) didn't collapse the instructions from the two inlined calls into one.<br> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
