Thanks, that's a fair point. This patch would still let llvm-dwarfdump and LLDB consume generic DWARF and source-line information from Go-produced Mach-O and COFF binaries without the Go language plugin, but the main motivation was the Go plugin work. Since #212598 will not move forward and I cannot commit to long-term upstream maintenance, I will keep the LLGo-specific integration in the LLGo repository instead. Closing this PR.
