Hi Abner,
Yes, the PE/COFF has been adapted to LoongArch32 and LoongArch64, please refer 
to: https://docs.microsoft.com/en-us/windows/win32/debug/pe-format 
(https://link.getmailspring.com/link/9a61f0c8-a7fa-41ad-b0f6-769ec7687...@getmailspring.com/0?redirect=https%3A%2F%2Fdocs.microsoft.com%2Fen-us%2Fwindows%2Fwin32%2Fdebug%2Fpe-format&recipient=ZGV2ZWxAZWRrMi5ncm91cHMuaW8%3D)
 and search "LoongArch" for more information.

Thanks,
Chao
