downgrade-mangling-error_clang_12.patch (1105B)
1 Downgrade unimplemented mangling diagnostic from error to note. 2 This codepath is exercised by MozsearchIndexer.cpp (the searchfox 3 indexer) when indexing on Windows. We can do without having the 4 unimplemented bits for now as long the compiler doesn't fail the 5 build.
