[Openmp-commits] [PATCH] D116959: [DWARF] Try not to crash for codes with missing debug information

[David Blaikie via Phabricator via Openmp-commits]

dblaikie added a comment.

I did eventually figure out why the !dbg is important - `findPrologueEndLoc` returns a null DebugLoc if there are no !dbg attachments, so avoids the DISubprogram dereference that way. So, yeah, at least now I understand why this only happens in a non-debug-having function that has debug locations in it, only under NVPTX.

Thanks for your patience :)
