[PATCH] D88603: [WebAssembly] Add support for DWARF type units

[Derek Schuff via Phabricator via llvm-commits]

dschuff added a comment.

@sbc100 I found that the cause of the assertion is that 
in dwarf 5, the type units apparently go in the .debug_info section (instead of the .debug_type section), and this section already exists (but it was created as a non-comdat).
So when `getWasmSection` tries to look up an existing section it fails because the group is part of the key. Then it tries to create a new section but that fails because the name is duplicate.

For some reason this doesn't happen or is not a problem with ELF but I haven't looked up why yet.
For now I just disabled the dwarf5+TU tests since we don't really use dwarf5 yet anyway.
