[PATCH] D94976: [DWARF] Create subprogram's DIE in the unit specified by its DISubprogram

[David Blaikie via Phabricator via llvm-commits]

dblaikie added a comment.

Could be related to a change I made maybe a couple of years ago to avoid emitting split units when there was nothing of interest in the split unit. I forget where that code is exactly - but this was part of a set of fixes I made for a few related issues due to a ThinLTO debug info case - something was causing excess CU fragments under ThinLTO, ecah of which was being split even though there wasn't anything interesting in the split part.

Might be necessary to tweak the condition for that CU elision - I can go looking for more detail on exactly where/how that works, if you like.
