Description

It seems as though there are still a few optimization passes that invalidate DWARF, so they are disabled when DWARF output is requested. Is there any plan to implement DWARF support for these passes? It would be useful to be able to generate DWARF output with a Release build and split DWARF so the debug symbols can be uploaded to Sentry (for example).

Research direction

Start by locating the optimization passes that are disabled when DWARF output is requested, then trace the existing DWARF handling. Done means those passes can run with DWARF output, including Release and split-DWARF builds suitable for uploading debug symbols to Sentry.
