Ok I went for kind of middle ground solution, I patch in the obj files, but as adding a new section didn't seem to work, I add a "shadow" section, by editing the pointer to line number and the virtual size on the .debug$T section. Although technically broken, both link.exe and lld-link.exe don't seem to mind the alterations and as the shadow .debug$H is not really a section

We don't generate any .lib as those don't work well with incremental linking (and give zero advantages when linking AFAIK), and it would be pretty easy to have a modern format for having a .ghash for multiple files, something simple like size prefixed name and then size prefixed ghash blobs.

...Sections / getSectionName) looking for .debug$T and .debug$H sections. If you find a .debug$H section then you can just skip that object file. If you find a .debug$T but not a .debug$H, then basically do the same thing that LLD does in PDBLinker::mergeDebugT (create a CVTypeArray, and pass it to GloballyHashedType::hashTypes. That will return an array of hash values. (the format of .debug$H is the header, followed by the hash values). Then when you're writing the list of sections, just add in the .debug$H section right after the .debug$T section. Currently llvm-objcopy only writes ELF files, so it w...
